A Review of Low Power Wide Area Technology in Licensed and Unlicensed Spectru...journalBEEI
There are many platforms in licensed and license free spectrum that support LPWA (low power wide area) technology in the current markets. However, lack of standardization of the different platforms can be a challenge for an interoperable IoT environment. Therefore understanding the features of each technology platform is essential to be able to differentiate how the technology can be matched to a specific IoT application profile. This paper provides an analysis of LPWA underlying technology in licensed and unlicensed spectrum by means of literature review and comparative assessment of Sigfox, LoRa, NB-IoT and LTE-M. We review their technical aspect and discussed the pros and cons in terms of their technical and other deployment features. General IoT application requirements is also presented and linked to the deployment factors to give an insight of how different applications profiles is associated to the right technology platform, thus provide a simple guideline on how to match a specific application profile with the best fit connectivity features.
Low-power wide area networking technology offers long-range communication, enabling new types of IoT services. LoRaWAN is one of the most adopted solutions, providing ubiquitous connectivity for outdoor applications. However, its capabilities and limitations are not well understood. The authors provide an impartial overview of LoRaWAN's limitations to avoid unrealistic expectations, discussing use cases where it works and does not work, and listing open research questions.

This will allow 5G to provide significantly higher data rates through techniques like massive MIMO and advanced beamforming. 5G will also target requirements for low latency connectivity in areas like vehicle-to-everything communication and industrial IoT. The evolution of 5G is expected to start within existing LTE networks and expand to new radio technologies operating at frequencies above 30GHz.
A Review of Low Power Wide Area Technology in Licensed and Unlicensed Spectru...journalBEEI
There are many platforms in licensed and license free spectrum that support LPWA (low power wide area) technology in the current markets. However, lack of standardization of the different platforms can be a challenge for an interoperable IoT environment. Therefore understanding the features of each technology platform is essential to be able to differentiate how the technology can be matched to a specific IoT application profile. This paper provides an analysis of LPWA underlying technology in licensed and unlicensed spectrum by means of literature review and comparative assessment of Sigfox, LoRa, NB-IoT and LTE-M. We review their technical aspect and discussed the pros and cons in terms of their technical and other deployment features. General IoT application requirements is also presented and linked to the deployment factors to give an insight of how different applications profiles is associated to the right technology platform, thus provide a simple guideline on how to match a specific application profile with the best fit connectivity features.
Low-power wide area networking technology offers long-range communication, enabling new types of IoT services. LoRaWAN is one of the most adopted solutions, providing ubiquitous connectivity for outdoor applications. However, its capabilities and limitations are not well understood. The authors provide an impartial overview of LoRaWAN's limitations to avoid unrealistic expectations, discussing use cases where it works and does not work, and listing open research questions.
The quality of service of the deployed LTE technology by mobile network opera...IJECEIAES
In this study, the real-world performance analysis of four Nigerian mobile network operators (MNOs), namely MTN, GLO, Airtel, and 9Mobile longterm evolution (LTE) cellular network, were analyzed and compared. The Nigerian MNOs utilize 5 MHz, 10 MH, and 20 MHz channel bandwidths based on third-generation partnership project’s (3 GPPs) recommendation. The presented analysis shows the uplink (UL), and downlink (DL) throughputs gaps in mobility condition as well as other LTE’s system quality of service (QoS) key performance indicators (KPI’s) of: Connection drop rate, connection failure rate, peak physical downlink throughput, minimum radio link control (RLC) downlink throughput threshold and latency are not strictly followed. The reason may be due to a lack of regulatory oversight enforcement. The comparative studies showed that MTN provides the best QoS. The introduction of novel LTE QoS metrics herein referred to as national independent wireless broadband quality reporting (NIWBQR) is the significant contribution of this study. The goal of this study is to show the quality of the network as it affects the user's experience. Important observation showed that all the MNOs are not adhering to the 3 GPPs specified user plane latency of 30 ms and control plane latency of 100 ms, respectively, which makes video streaming and low latency communication a near-impossible task.
NB-IoT: a sustainable technology for connecting billions of devicesEricsson
Under the umbrella of 3GPP, radio-access technologies for mobile broadband have evolved effectively to provide connectivity to billions of subscribers and things. Within this ecosystem, the standardization of a radio technology for massive MTC applications – narrowband IoT (NB-IoT) – is also evolving. The aim is for this technology to provide cost-effective connectivity to billions of IoT devices, supporting low power consumption, the use of low-cost devices, and provision of excellent coverage – all rolled out as software on top of existing LTE infrastructure. The design of NB-IoT mimics that of LTE, facilitating radio network evolution and efficient coexistence with MBB, reducing time to market, and reaping the benefits of standardization and economies of scale.
The IoT embeds a broad range of MTC applications, and among the different types, massive MTC – including applications like smart metering, agriculture and real estate monitoring – sets a number of performance targets for connectivity. Attempting to meet these IoT targets using a radio-access technology designed for mobile broadband, however, doesn't make economic sense. Networks that provide connectivity to massive MTC applications need a radio-access technology that can deliver widespread coverage and low power consumption, often in signal-challenged locations. Hence the need for narrowband-IoT (NB-IoT).
NB-IoT is a 3GPP radio-access technology designed to meet the connectivity requirements for massive MTC applications, as well as the design targets for IoT including low device cost, extended coverage, 40 devices per household, long battery life, and uplink latency of under 10 seconds.
NB-IoT enjoys all the benefits of licensed spectrum, the feature richness of EPC, and the overall ecosystem spread of 3GPP. At the same time, NB-IoT has been designed to meet the challenging TCO structure of the IoT market.
This articles reveals how NB-IoT is being designed and how it can be deployed in GSM spectrum, within an LTE carrier, or in an LTE or WCDMA guard band.

IRJET- Viability of Smart City Applications with Lora WANIRJET Journal
This document discusses the viability of using LoRa WAN for smart city applications. It summarizes the LoRa WAN technology, including its long range capabilities and low power consumption. It then describes two case studies of using LoRa WAN for air quality and congestion monitoring in London. The results show that LoRa WAN is a feasible low power solution for these types of smart city applications. Battery lifetimes of several years can be achieved, meeting requirements for monitoring networks. Therefore, LoRa WAN shows potential as an effective technology for implementing IoT in smart cities.
What are the differences and relationships between LTE-M and NB-IoT?
What is LTE-M?
LTE-M, or LTE-Machine-to-Machine, is an LTE evolution-based IoT technology, called Low-Cost MTC in R12 and LTE enhanced MTC (eMTC) in R13, designed to meet the needs of IoT devices based on existing LTE carriers.
The full name of eMTC is enhanced Machine-Type Communication. It is the LTE network between machines using LTE communication for the IoT. It is often abbreviated as M2M.
A response to the growing interest in IoT and LPWAN, LTE-M is unique in that it can be very energy efficient and transmit up to 10 bytes of data per day, but can also transmit up to one megabit per second. LTE-M serves a very wide range of use cases.
IoT technologies are mainly in the areas of communication and sensors. This article is about IoT technology NB-IoT vs LoRa technology.
What is the classification of IoT communication technology?
There are many wireless communication technologies for IoT, mainly divided into two categories: one is Zigbee, Wi-Fi, Bluetooth, Z-wave, and other short-range communication technologies; the other is LPWAN (low-power Wide-Area Network), i.e. wide-area network communication technology.
LPWAN can be further divided into two categories: one is LoRa, SigFox, and other technologies working in the unlicensed spectrum; the other is 2G/3G/4G cellular communication technologies working in licensed spectrum and supported by 3GPP, such as EC-GSM, LTE Cat-m, NB-IoT, etc.

Performance Analysis of WiMAX and LTE Using NS-2IJERA Editor
The increasing use of wireless devices and in particular smart phones has resulted the need for greater capacity
and higher speed than the existing network technologies. Hence, LTE (Long Term Evolution) and WiMAX
(Worldwide Interoper- ability for Microwave Access) became the two leading technologies. Services are
increasingly shifting from voice to data and from circuit-switched to packet-switched ones. Battle between LTE
and WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards
through IEEE 802.16 and is up and running but lacks in substantial roll out plans due to cost. The targets for
LTE indicate bandwidth increases as high as 100 Mbps on the downlink, and up to 50 Mbps on the uplink.
However, this potential increase in bandwidth is just a small part of the overall improvement LTE aims to
provide. This study illustrates the model and representation of LTE links and traffics using NS-2 network
simulator and observation of TCP performance investigated. The Evaluation of the network performance with
TCP is mainly based on congestion window behavior, throughput, average delay and lost packet.
This document provides an overview of low-power wide-area networks (LPWAN) for internet of things (IoT) applications. It introduces different LPWAN technologies including LoRa, Sigfox, and NB-IoT and compares their characteristics such as data rates, power consumption, range, and security features. The document also discusses LPWAN standards from various standards bodies and the benefits of using LPWAN networks, concluding that each technology is suited for different IoT use cases depending on cost, battery life, range, and communication needs.
IMPLEMENTATION OF AN INTELLIGENT MOTION DETECTORIRJET Journal
This document describes the implementation of an intelligent motion detector that can detect the direction of motion (left, right, up, down). It uses a Raspberry Pi to analyze signals from a 4x4 PIR sensor array. Python code is written to detect motion direction by analyzing timestamps from multiple motion sensors. When a sensor is activated, the timestamp is recorded. By looking at the sequence of timestamps, the direction of motion can be inferred. The code defines functions to detect motion in each direction by comparing the relative timestamps in the motion sensor arrays. When motion is detected, the direction is printed and the arrays are cleared.
Data Communication in Internet of Things: Vision, Challenges and Future Direc...TELKOMNIKA JOURNAL
Ubiquitous technologies based heterogeneous networks has opened a new paradigm of technologies, which are enabled with various different objects called Internet of things (IoT). This field opens new door for innovative and advance patterns with considerable potential advantages in the shape of plethora of monitoring and infotainment applications around us. Data communication is one of the significant area of research in IoT due to its diverse network topologies, where diverse gadgets and devices have integrated and connected with each other. In order to communicate among devices and users, routing should be relible, secure and efficient. Due to diverse and hetrogenous netwok environment, the most of the existing routing solutions do not provide all quality of services requirement in the network. In this paper, we discuss the existing routing trend in IoT, vision and current challenges. This paper also elaborates the technologies and domains to drive this field for future perspectives. The paper concludes with discussion and main points for new researchers in terms of routing to understand about current situation in IoT.
Systematic literature survey: applications of LoRa communicationIJECEIAES
LoRa is a communication scheme that is part of the low power wide area network (LPWAN) technology using ISM bands. It has seen extensive documentation and use in research and industry due to its long coverage ranges of up-to 20 km or more with less than 14 dB transmit power. Moreover, some applications report theoretical battery lives of up to 10 years for field deployed modules utilising the scheme in wireless sensor network (WSN) applications. Additionally, the scheme is very resilient to losses from noise, as well as bursts of interference through its forward error correction (FEC) scheme . Our objective is to systematically review the empirical evidence of the use-cases of LoRa in rural landscapes, metrics and the relevant validation schemes. In addition, the research is evaluated based on (i) mathematical function of the scheme (bandwidth use, spreading factor, symbol rate, chip rate and nominal bit rate) (ii) usecases (iii) test-beds, metrics of evaluation and (iv) validation methods. A systematic literature review of published refereed primary studies on LoRa applications was conducted using articles from 2010-2019. We identified 21 relevant primary studies. These reported a range of different assessments of LoRa with 10 out of 21 reporting on novel use cases. The authors conclude that more work is needed in terms of field testing, as no articles could be found on performance/deployment in Botswana or South Africa despite the existence of LoRa networks in both countries. Thus researchers in the region can research propagation models performance, the energy efficiency of the scheme and MAC layer as well as the channel access challenges for the region.
SCALABILITY CONCERNS OF CHIRP SPREAD SPECTRUM FOR LPWAN APPLICATIONSijasuc
Divergent modulation schemes have been proposed for the Internet of Things (IoT). Low Power Wide Area
Networks (LPWAN) technologies are gaining unprecedented acceptance in IoT application of sensor
networks. Chirp Spread Spectrum (CSS) is a prominent modulation technique proposed for LPWAN. Chirps
can traverse long distance and are resilient to noise and Doppler effects. Noise resilience along with
transmission range and low power requirement makes CSS a preferred modulation scheme for sensor
networks. LoRaWANTM, with its physical (PHY) layer using CSS, has emerged as the widely accepted
LPWAN solution. By using CSS modulation with orthogonal spreading factors (SF), LoRa offers wide
coverage to LPWAN applications while supporting a high volume of devices. However, scalability
performance of CSS has not been inadequately modeled. As with the suitability of the modulation scheme,
there are concerns on how chirps interact with the surrounding as the number of deployments bursts out
into higher volumes. We evaluate CSS at ISM band 868 MHz for spreading factor 7 to 12 at bandwidth 125
kHz for performance and scalability. Simultaneous transmissions were simulated with repeated iterations
and conclusions are arrived on collisions rate, packet error rate, and bit error. Suitability of using CSS for
sensor networks for future deployments is commended.

This document discusses the scalability concerns of Chirp Spread Spectrum (CSS) modulation for Low Power Wide Area Network (LPWAN) applications. CSS is a prominent modulation technique used in LPWAN technologies like LoRaWAN. While CSS provides noise resilience, long transmission range and low power requirements making it suitable for sensor networks, its ability to scale to a very large number of simultaneous transmissions has not been adequately modeled. The document aims to evaluate the performance and scalability of CSS at different spreading factors through simulations of simultaneous transmissions over an AWGN channel. Key performance metrics like collision rate, packet error rate and bit error are analyzed to assess the suitability of CSS for future large-scale sensor network deployments.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

are connected worldwide through cellular networks using 2G, 3G, and 4G. The rollout
of C-IoT systems, e.g., NB-IoT, LTE -M, and EC-GSM-IoT is expected to boost the IoT
business of telecom operators. On the other hand, a plethora of low power extensive area
networks (LPWAN) and low power local area networks (LPLAN) technologies like Sig-
fox, LoRaWAN, Weightless N/P, Z-Wave, Dash-7, BLE, Zigbee, LoRa, 802.11ah, and
802.15.4k are available to provide indoor and outdoor coverage. Currently, there are around
twenty IoT connectivity solutions available in the market. Most importantly, the end-user
device modules of these technologies are available in the market.
So far, most of these technologies, both C-IoT and non-cellular LPWAN technologies,
are still at the pilot phase with a small area coverage and service provisioning. The cost-
effectiveness of an IoT communication technology is not sure from an IoT service provider
and communication service providers’ perspective. The scalability and viability of these
technologies are a concern. Researchers performed a number of studies on Network-Eco-
nomics’ studies on GSM [2], WCDMA [3, 4], and LTE [5–10]. Moreover, there are plenty
of studies on IoT business modeling [11, 12] and value network [13, 14]. In [15], market
research company Mobile Experts provides a return of investment (ROI) calculations pre-
dicted for LPWA and cellular-IoT solutions. To the best of our knowledge, IoT connectivity
service scalability has not yet received the necessary attention in scientific research. Hence,
there is currently a research gap related to understanding different architecture choices and
their impact on IoT communication systems’ scalability.
Furthermore, technical papers present intra-technology interference challenges in
the unlicensed band [16–18]. In [16], a survey has been performed to identify the gap of
LPWAN unlicensed band research. The study has identified the uncoordinated coexistence
of devices as a key challenge that may affect the coexisting technologies’ packet transmis-
sion performance. [17] shows the impact of cross technologies like camera, analog phone,
FH phone, and microwave on IEEE 802.15.4. Interference impact between LoRa and IEEE
802.15.4 shows in [18]. Also, coexistence impact of LoRa and IEEE 802.11n (WiFi) is
studied and presented in [19]. Due to the modulation scheme, LoRa is more resilient to
interference than IEEE 802.11n and IEEE 802.15.4. Also, the paper points out the trade-off
between bit rate and spreading factor that limits the data rate. A measurement base inter-
ference impact of sub-one GHz technologies in LoRa presented in paper [20]. The results
show that Sigfox interference in the worst case can result in 28% losses. Similar observa-
tion is found in [21] for IoT devices in mobility. Till to date, no work assesses the coexist-
ence impact of LoRaWAN and Sigfox. Also, the coexistence impact of LoRaWAN and
Sigfox on each other’s scalability is not investigated thoroughly.
Henceforth, this paper extends the discussion of [22] focusing on the deployment
options and cost-structure of IoT communication service scalability. To do so, first, we
investigate the coexistence impact of LoRaWAN and Sigfox on each other’s scalability.
Then we assess the cost-effectiveness of C-IoT and LPWA technologies. This paper aims
to compare C-IoT and non-cellular LPWAN technologies’ scalability advantages and dis-
advantages in terms of rollout cost. We study deployment options in Urban and Rural sce-
narios and using unlicensed and licensed bands. Overall, we check the cost structure of
IoT communication systems to answer the overall question: ’What are the advantages and
disadvantages of LPWAN technologies to build a network in different scenarios?’
We answer the question from the IoT communication service providers’ (CSPs) perspec-
tive. To answer this question, we consider IoT service deployments in the urban and rural
context. In this study, we compare Sigfox, LoRaWAN, NB-IoT, LTE-M, and EC-GSM-IoT
to understand the practicality of each technology under rural and urban use-cases. We ana-
lyze the inter-technology interference impact on the scalability of Sigfox and LoRaWAN.

The main contributions of this paper are: (1) the cost comparison of LPWAN in urban and
rural deployments, (2) identification of the key cost drivers of LPWAN network rollout,
(3) the impact of inter-technology interference on the LPWA scalability in the unlicensed
band, and (4) extending understanding and motivation of the need for IoT communication
technologies mix to optimize the profitability.
The paper is outlined as follows; Sect. 2 covers the overview of studied technologies.
Section 3 describes the research approach and method. Section 4 elaborates the assump-
tions and considered scenarios. Section 5 illustrates the results. Findings and discussions
are listed in Sect. 6, and conclusions are presented in Sect. 7.
2 Overview of LPWAN Technologies
This section describes the main characteristics of Sigfox, LoRaWAN, NB-IoT, LTE-M, and
EC-GSM-IoT briefly. Table 1 illustrates the specifications of the selected IoT communi-
cation technologies. We have collected the technology specifications based on academic
articles [23, 24, 28–30], standardization specifications [25, 26] and white papers [27, 28].
2.1 Sigfox
Sigfox is a proprietary ultra-narrowband (UNB) technology that operates in an unlicensed
ISM band. In Europe, it operates at 868 MHz, and in North America, it operates at 915
MHz. Sigfox offers an end-to-end IoT connectivity solution in 45 different countries
globally along with a connectivity platform service. Sigfox uses binary phase-shift key-
ing (BPSK) modulation in the ultra-narrow band (100 Hz) that gives low noise level, low
power consumption, and high receiver sensitivity. As a result, larger area coverage with a
simple end-device antenna design is achieved with Sigfox. The simple end-device antenna
design assures a longer battery lifetime but with the cost of throughput. Sigfox data rate
is only 100 bps. Due to regulation, a device can transmit 140 messages per day and can
receive eight messages per day. The transmission works in a ’fire and forgets’ manner
where a device transmits the message three times in different frequency and period, which

reasonably assures the message delivery rate to 95%. The payload size is 12 bytes with 14
bytes of overhead. The more significant advantage of Sigfox is that the country operators
only deploy and manage the radio networks where the OSS/BSS and platform are central-
ized and shared by all the operators in the world.
2.2 LoRaWAN
LoRaWAN is adapted from LoRa and modulates in the unlicensed SubGHz band. For
modulation, it uses the proprietary chirp spread spectrum (CSS) techniques. LoRaWAN
shares ISM Band 868 MHz in Europe and 915 MHz in North America along with Sigfox.
It also supports the limited bi-directional transmission of a narrowband signal over broader
channel bandwidth. LoRaWAN uses spreading factors (SFs) that give a trade-off between
extended coverage area and bandwidth. Depending on different SF, the data rate can vary
between 300 bps and 50 kbps. This means the cell edge user can transmit at 300bps, and
the closer a device to the access point, the higher throughput a device can achieve through
LoRaWAN [22]. Due to the regulation policy, LoRAWAN has 1% duty cycle, which can be
translated to 36 sec/hour transmission per device per channel.
2.3 NB‑IoT
Narrowband-IoT (NB-IoT) is standardized in 3GPP release-13. NB-IoT can be consid-
ered as another track dependent on the current 3GPP innovation particulars. NB-IoT can
be deployed in Licensed (in-band, guard band. Standalone) and unlicensed band. In the
licensed band, there are no limitations on the duty cycle. In the unlicensed band, the duty
cycle depends on the spectrum regulation policy of the specific region. NB-IoT occupies
one resource block of LTE systems, corresponds to 180 kHz in the frequency band. In
NB-IoT new radio is introduced to optimize the battery efficiency and coverage [23]. NB-
IoT provides extended coverage (164 dB) and can support a long battery lifetime (up to 15
years). Future NB-IoT will extend to include services like localization, and multicast, in the
upcoming release [23].
2.4 LTE‑M
LTE-M, also known as LTE-MTC or LTE CAT-M, is a 3GPP Release-13 LPWAN series
C-IoT communication technology. Like other LPWAN technologies, IoT service targeted
LTE-M is designed to conserve battery power and can offer up to 10-years battery lifetime
with 5 watt-hour battery1
. The data rate may vary between 10 kbps and 1 Mbps. LTE-M
can be deployed inband to LTE, where the LTE service can coexist within the same band-
width. TTI bundling, repetition, and narrowband retuning are the key features to achieve
extensive coverage (
≈ 164.7dB
) of LTE-M [30]. By reducing end-device design complex-
ity, Cat-M devices’ cost would be comparable to GSM devices. LTE-M can support posi-
tioning service with multicast and mobility. Additionally, the voice over LTE (VoLTE)
service can be supported by LTE-M. LTE-M is expected to be deployed with a simple soft-
ware upgrade in addition to the existing LTE’s radio system but not backward compatible.

2.5 EC‑GSM‑IoT
EC-GSM is the enhanced GSM that reuses GSM and CDMA technology with changes
on the logical channel to enhance the coverage. Long battery life, low device cost relative
to GPRS/GSM devices, extended coverage, and variable rates are all benefits of extended
DRX with radio control level enhancements. In contrast to GSM, it can support a large
number of devices while providing enhanced security. Release-14 enables the positioning,
makes at least 3 dB MCL improvement for low power devices on all uplinks, and uses
alternative mappings of blind physical layer transmissions for higher coverage classes [31].
This results in 20 dB coverage improvement. The expected battery lifetime for EC-GSM is
more than ten years.
Additionally, EC-GSM delivers EDGE support, which provides instantaneous global
coverage and allows the maximum throughput of 355 kbps. A simple software upgrade
of existing GSM deployments should be enough to avail of such services. Also, due to the
expiration of the device module patents, the module cost for EC-GSM is expected to be the
lowest among the 3GPP-defined technologies [31].
3 Research Approach
This section describes the method, analytical approach, scenarios, and assumptions that are
considered in this paper. We analyze the cost-capacity features of C-IoT and non-Cellular
IoT systems. The analysis includes network dimensioning and costs analysis.2
3.1 Viability Assessment Method
The typical lifecycle of a network consists of three phases: planning, rollout, operation, and
maintenance. The planning phase is critical for assessing the business viability of a deploy-
ment. This is the first step in determining how to realize and minimize the risk associated
with a specific business goal or technology implementation. The aim is to lower the invest-
ment risk and understand how a specific technology will better meet a business goal with
a specific technology. A thorough techno-economic analysis, which includes qualitative
business analysis, technical performance analysis of the subject technology, and qualita-
tive assessment of the technology, is required for the validity check.If all three parameters
assessments suggest business scalability with positive cash flow, the CSPs then move to
the second phase of the initial rollout. At year zero, a CSP invests a significant amount to
network rollout.
Extend the investment over the years, first to ensure coverage and then to ensure service
efficiency by continual operation and maintenance, followed by a continuous investment in
technology and network extension, which is the third step, which operates almost parallel
to the second. The second phase’s investment is a considerable upfront investment typically
considers as capital expenditure (CAPEX). Costs like the maintenance cost and electric-
ity fees are considered as the regular incurring cost, known as an operational expenditure
(OPEX).

3.2 Network Dimensioning
Figure 1 illustrates the proposed assessment framework for IoT communication service
providers. The demand profile is created here based on the service, device, and scenario
requirements. The number of devices and their normalized duty cycle are a likely con-
sequence of the IoT service case’s demand. Capacity is calculated based on the techni-
cal specification like bandwidth, data rate, and modulation, along with regulations. For
instance, technologies that are operating at the unlicensed band would face restrictions
on the end-user activity pattern. The required number of sites is estimated using the
framework explained in [22], based on the demand and capacity profile. We consider
four key parameters for the capacity trade-offs:
1. Coverage: number of the site to area coverage
2. Device capacity per site
3. Data capacity per site per day
4. Message transmission capacity per site per day based on the ’time on-air’ calculation
Network dimensioning gives the required number of equipment, fronthaul, and backhaul
bandwidth.
In addition, as seen in Fig. 2, we found three different types of cell patterns. Omni-
directional, null sector, and sectorized cell are relevant patterns for meeting certain per-
formance criteria. For example, Sigfox uses 3-RAT null-sector strategy where there is
no sector within a cell. If a device transmits a payload, all the nearby receivers receive
the message. Then, forward the message to the core. OSS/BSS then detects and dis-
cards the duplicate packets if the core network receives multiple packets. In such a way,
the network can increase the link availability and accessibility performance rate. How-
ever, this strategy potentially wastes lots of radio resources and may become a barrier to
scale up the cell capacity where the sectorized cell is suitable for capacity densification.
Omni-directional antenna takes less rollout cost as we can potentially deploy a single
antenna per cell.

Furthermore, we consider the coexistence impact of LoRaWAN and Sigfox in the
unlicensed band. We evaluate the scalability limits of LoRaWAN and Sigfox to meet the
95% packet delivery rate. In section V, we present the result of our simulations in detail.
According to the simulation results, we show that LoRaWAN and Sigfox can coexist with
slide performance deprivation. In coexistence case, packet loss for Sigfox and LoRaWAN
is around 3% and 4.5%, respectively.
To calculate the required number of sites for area coverage, first, we estimate the
cell range from path loss. The path-loss is calculated using the sensitivity of the receiv-
ers, transmit power, antenna gain, and transmitter parameters. Then, for urban outdoor to
indoor attenuation and rural outdoor attenuation, we use the Okumura-Hata propagation
model. The derived cell range of different technologies can be found in Table 2. In this cal-
culation, we consider all the sensor devices have an antenna gain of 3 dB, and the receiver
antenna gain at the base station is set to 6 dB.
3.3 Cost Module
CAPEX and OPEX elements directly linked to the IoT radio access technologies (RATs)
deployment are considered as the total cost of ownership. The parameter considered in the
CAPEX and OPEX equations as shown in Fig. 3. Table 3 Lists the cost assumptions that
are taken from three primary sources. We took the NB-IoT, LTE-M cost assumptions from
METIS-II [24, 31]. Sigfox, and LoRAWAN from [7, 24].
The net present value (NPV) analysis is applied to account for the investment and opera-
tion cost. In this study, we only calculate NPV based on the cash flow related to network
deployment-related costs with a discount rate of 10%. The NPV for N years is calculated
as,

where Cyr is the annual total cash flow for the year yr. R is the discount rate, and yr is the
network operation period in years. Also, we assumed that the maintenance cost is increas-
ing at a rate of 5% per year.
3.4 Techno‑Economic Analysis
The techno-economic analysis is based on the qualitative results of the NPV, technical perfor-
mance, and business aspects, meaning the targeted IoT services and market share is considered
in this analysis. This is important because some technologies may come out cost-efficient from
a business perspective, but the technology is not viable. For example, if we see that technology
is viable for small-scale operations but not cost-effective for large-scale operations, lacking the
business aspect like a business goal and strategy, we can make a partial argument that may not
be accurate for all cases. In this case, the business case assumptions are reflected in terms of
market share and growth rate.

4 Assumptions
4.1 Scenario Description
We consider a large urban city and rural area in our use cases wherein urban city services
like smart home, smart metering, and smart city are the key focus. For rural areas, services
like forestry, farming industry monitoring, remote smart home, and smart elderly monitoring
services are considered. We consider an urban city area of 300 km2
and a rural city area of
10000 km2
. We considered the incumbent or brownfield and new market entrant or greenfield
scenarios. In each case, we analyzed the scenario in both extremely high and low device den-
sity cases. Additionally, we analyze the site builds and leasing cost in all cases. The incumbent
operators reuse the existing site for LPWAN rollout. We consider the unlicensed sub-GHz
band is used by LoRaWAN and Sigfox, and licensed band by NB-IoT, LTE-M, EC-GSM-IoT.
4.2 Traffic Demand
Table 4 elaborates on the assumption of traffic demand of our considered use cases. Stock-
holm’s population density is considered as baseline for the urban use-case, which is 3597
people∕km2
. The device penetration is 16 sensors per person in the high-density case and
50% of population density for the low-density case. For a rural area, the highest density of
trees per km2
in Sweden, which is 69967 trees∕km2
is considered. However, when it comes
to population density in rural areas in Sweden, it can be as low as 25 people∕km2
. In this
study, we take a normalized average, which is 100 people∕km2
. Now for the high-density
traffic case, it is assumed that the forestry monitoring services will be the key service, and
monitoring the trees will be the essential Industrial-IoT service for the Swedish timber
industry. This paper assumes that 70000 trees∕km2
will be under monitored by the end of
10 years of operation. Also, it is assumed that the devices’ growth rate is 50% in greenfield
cases and 35% in brownfield cases.

Results and Cost Analysis
In this section, first, we present a simulation-based inter-technology interference impact on
Sigfox and LoRaWAN scalability. Then we use this understanding to analyze the deploy-
ment cost structure.

5.1 Simulation Assumption
We perform a MATLAB-based simulation where one gateway per technology is consid-
ered. The cell range for Sigfox and LoRaWAN is taken from Table 2. Both technologies
can use the maximum allowed transmit power defined by ETSI. We consider different sen-
sitivity levels for different SF values. We assume each device generates one payload per
day. We only consider the performance over 1 min transmission. The details of the assump-
tions are listed in Table 5.
5.2 Scalability in Unlicensed Band
Figure 4 shows the scalability limits of LoRaWAN and Sigfox in an unlicensed band coex-
istence case. As one can see on the left subfigure of Fig. 4, LoRaWAN coexisting with
Sigfox on average can gain four packet collisions per minute with a 4.5% packet error rate.
As we did not consider the packet error recovery mechanism in detail, the error rate and the
failed transmission are equal. Some study has shown that depending on the collision loca-
tion, the recovery of the payload is possible. In such a case, the collision rate will reduce
from this observation. For simplicity and high-level understanding, we take into account
this error rate. So, where there are around 700 Sigfox devices, around 5% packet will be
erroneous.
For the Sigfox case, as illustrated on the right subfigure of Fig. 4, where 100 LoRa
devices are active, Sigfox devices encounter around 100 failed transmissions with 700
collisions. However, due to the 3-packet transmission in different times and channels, the
packet error rate is maximum around 3%. So, in the case of the best-effort transmission
assurance case, both the technology can coexist without hindering each other’s scalabil-
ity. Due to the duty cycle restriction and channel planning scope, we can assume that the
LoRaWAN and Sigfox devices experience negligible interference from each other’s trans-
mission in small traffic conditions.
5.3 Cost Analysis
This section presents the results and analyzes the cost of Urban and Rural deployment.
Figure 5 depicts the number of sites require to meet the coverage and device require-
ments. Due to extensive coverage, Sigfox usually requires fewer sites than other

technologies. However, when the device density is high in both Urban and Rural cases,
NB-IoT and EC-GSM- IoT requires less cell if C-IoT is deployed in the 3-cells sector. In
all cases, LoRaWAN requires many cells to meet the device density.
When it comes to greenfield to brownfield deployment, one can observe from the
subfigures of Fig. 6 that greenfield deployment is more costly than brownfield deploy-
ment. As the deployment cost includes new sites’ acquisition cost, equipment cost, new
deployment always takes up more costs than an upgrade of existing sites. It is interest-
ing to note that greenfield actors need to invest a substantial amount in capturing a small
market share than brownfield actors. On the other hand, brownfield actors can reuse
their infrastructure to deploy the LPWAN networks, which are cost-efficient and viable.
We can see a similar trend in the other three figures as well.
Figure 6 a and b illustrates the total cost breakdown of considered technologies
deployment and operations in an urban scenario. Figure 6a shows the cost breakdown of
deployment scenarios, SC1 and SC3 (see Table 4 for the scenario details). The brown-
field and greenfield represent SC1 and SC3, respectively. From the figures, we can say

that NB-IoT and EC-GSM take less investment for SC1, and for SC3, LoRaWAN meets
the low-cost requirements with less TCO than other technology options.
From Fig. 6b. one can see, LoRaWAN is cost-efficient in both SC2 and SC4 (see
Table 4) when the device density is low. This is because the required number of equipment
to meet the service demand is low. At the same time, the equipment pricing of LoRaWAN
is assumed to be lower than other technologies equipment.
Figure 6c and d depicts the cost breakdown for rural deployment scenarios. For SC5 and
SC7(see Table 4), EC-GSM is the most cost-effective solution (see Fig. 6c) in rural high
traffic scenarios. From Fig. 6d, we can say that LoRaWAN is the most cost-efficient solu-
tion, like Fig. 6b.
We can summarize the results of Fig. 6 by saying that LoRaWAN is cost-effective for
low device density scenarios where EC-GSM is cost-effective for large area and high-den-
sity cases like in this case for rural coverage. Four key cost drivers of LPWAN deploy-
ments are site, electricity, management, and installation cost. OPEX is the most significant
and dominant cost driver of LPWAN.
Figure 7 illustrates the effectiveness of infrastructure leasing vs. deployment. As
shown in Fig. 7a and b, site leasing is not profitable for Sigfox with a low density of
devices. This study assumes that Sigfox infrastructure cost and leasing cost are similar

to C-IoT devices costs. As the Sigfox base station’s device capacity and coverage range
are higher, it requires the majority of the investment at the initial phase and then does
not need to invest in those deployed cells. Hence, the recurring leasing cost turnouts
expensive than building own site. On the other hand, LoRaWAN requires massive
site deployments over years of operation. As a result, leasing turnouts profitable than
deploying their infrastructure under yearly gradual rollout of LoRaWAN.
Figure 8 a and b illustrate the overall network costs of the technologies in differ-
ent deployment options. We consider CAPEX and OPEX over time using NPV calcula-
tion. Also, we assume that all the technologies have an equal discount rate, which is
assumed 10%, in this case. As the figures represent the NPV based on the investment
over the years, the technology that gets the lower value is the cost-effective solution for
any deployment scenario.
Figure 8 a shows that NB-IoT is cost-effective in the SC3(Greenfield-Urban-High)
scenario when the device density is high. In SC4 (Greenfield-Urban-Low), when the
device density is low, LoRaWAN is cost-effective among the considered RATs. In the
rural case for SC7 (Greenfield-Rural-High) when the device density and traffic den-
sity are considered at the upper bound, EC-GSM is cost-effective for site leasing and

NB-IoT is cost-effective for site deployment case. For SC8, LoRaWAN is viable in both
leasing and sites deploy strategy.
Figure 8b shows that for SC1 (Incumbent-Urban-High), NB-IoT is cost-effective with
leasing, and LTE-M is cost-effective in site build case. This means NB-IoT and LTE-M
are more cost-effective than other technologies for existing operations. LoRaWAN is
viable for low device density case SC2 (Incumbent-Urban-Low). Similarly, in SC6
(Incumbent-Rural-Low), LoRaWAN is cost-effective in both leasing and building strat-
egy, and EC-GSM is cost-efficient in both leasing and site-building of SC5 cases.
6 Discussion and Findings
This analysis compared the network deployment options of five LPWAN technologies in
urban and rural areas. We studied the scalability impact of Sigfox and LoRaWAN in a
coexistence scenario. According to our observation, LoRaWAN and Sigfox can coexist
with minor performance degradation in the sub-GHz unlicensed band. It is important to
note that we did not consider any other technologies impact in this study. We partially
address the coexistence issue, but the question about the assurance of the service avail-
ability and the impact of coexistence of other technologies is not guaranteed. The exist-
ence of more technologies can further degrade performance.
Coming to the question, ’What are the advantages and disadvantages of LPWAN
technologies to build a network in different scenarios?’ The cost analysis indicates that
LoRaWAN is cost-efficient in scenarios where the device density is low. In the case
of the high density of devices for urban areas, NB-IoT and LTE-M are cost-efficient.
For rural areas, EC-GSM-IoT is cost-efficient. If we consider a Greenfield CSP business
goal that targets a small customer base with nominal market share, in such settings, we
can say that LoRaWAN with site leasing is plausible for such CSP as they can con-
centrate on one technology for service provisioning. In [15], the author compared the
NB-IoT and LoRaWAN deployment cost structure in terms of TCO. In the report, the
economic analysis also shows a similar trend for nationwide deployment cases. We can
say, LoRaWAN will give new entrant CSPs the roam to invest more in market penetra-
tion and sales strategy.
Now, even though we showed the coexistence impact is limited due to the duty cycle
bindings. We can argue that LoRaWAN cannot provide a service guarantee, limiting the
CSP’s service provisioning rage in IoT service offerings.
Although in our considered use cases, Sigfox is not the cost-efficient solution, Sig-
fox, today, can provide end-to-end service provisioning and complete connectivity solu-
tion regardless they have proprietary technology. However, Sigfox is offering open and
standard API and making many of the patents public, eventually reducing the device
module price. Additionally, Sigfox has a ready and running platform and API ecosys-
tem, which in many ways can be beneficial for an IoT service provider.
Furthermore, LTE-M can provide IoT services and enable voice over LTE (VoLTE)
service. This can bring big motivation for operators as VoLTE can reduce and simplify
today’s hierarchical network by entailing quality assured voice service for users. Hence,
cost-effectiveness may play a crucial role, but it may not be the primary role at the
beginning of the deployment. However, we can say it will draw attention when scalable
service provisioning is required for IoT communication services.

Future research should extend the unlicensed band technologies’ coexistence impact on
each technology’s scalability and packet delivery performance, which may change our find-
ings with more realistic performance metrics.
7 Conclusion
This paper presents an inclusive framework for analyzing the cost structure of an LPWAN
technology rollout. We argue that the quantitative cost analysis is not enough for the viabil-
ity analysis of the LPWAN rollout. Instead, we need to consider business requirements,
technological performance, and cost-efficiency to analyze and select cost-effective and
credible LPWAN solutions. Moreover, our study on the coexistence of LPWA technolo-
gies shed light on the concern of Sigfox and LoRaWAN coexistence. Thanks to the duty
cycle regulation, the coexistence of Sigfox and LoRaWAN can still meet 95% packet deliv-
ery rate requirements. Furthermore, the cost-benefit analysis results suggest that CSPs may
achieve cost-efficient deployment with single technology base rural and urban rollouts in
a low density of devices. However, this is decidedly case-specific and limited to scenar-
ios and traffic conditions. For instance, LoRaWAN is cost-effective to deploy in rural and
urban areas when the device density and device activity rate are low. In all other cases,
different technologies proved to be cost-efficient in different scenarios. So, if an operator
wants to achieve a broader market share with extensive coverage, the single technology-
based rollout may not be cost-effective. Also, our results suggest that leasing is not always
cost-effective for all IoT communication service rollout.
