Wireless broadband operators constantly face challenges of balancing the economics to deploy a robust and reliable wireless broadband service in suburban-rural areas or at cell-edges. Till to date, a large portion of these areas still remains hugely underserved or receiving unreliable coverage.
This paper in retrospect functions to further solidify the technological advantage of WiMAX, where we explore and proof the concept of suburban-rural deployment through the optimal pairing of a proper CPE strategy.
This paper explores deep into the technical and implementation advantages of an outdoor CPE solution, including the concept of antenna gain, transmission power, integrated POE design and environment-proof enclosure; and the effective advantage of Line of Sight performance and decreased penetration loss amongst other features of an outdoor CPE. We will also explore the misconception behind the high incremental cost, difficulty of engineering installation and service challenges in operations with the implementation of an outdoor CPE.

NLOS Wireless Backhaul for Small Cells - TCO Comparison with Optical FiberFrank Rayal
Mobile network operators (MNOs) are increasingly focused on meeting the explosive demand for data services. Deploying small, below-the-clutter cells is another technique to solve the capacity ‘hot spot’ problem as well as to provide service in ‘coverage holes’ in mobile networks that were designed primarily to carry voice traffic. However, there are technical and economic constraints that prevent network operators from deploying small cells: backhaul is one such constraint. This paper describes the value proposition of BLiNQ’s NLOS wireless backhaul solution and compares its total cost of ownership to that of optical fiber.
The document provides guidance on designing a wireless mesh network. It discusses beginning the design process with a satellite view of the deployment area to identify the root and relay nodes. Node locations are influenced by factors like the start and end points of bandwidth, points of needed bandwidth, and limitations of antennas and mounting locations. The document also provides information on estimating node ranges using a link budget calculator and selecting appropriate antennas based on the type of deployment, such as urban, rural, harbor, campground or mining scenarios. Recommendations are given for antenna selection and channel usage to avoid signal overlap.

MeshDynamics' patented low latency multiple radio wireless mesh preserves high performance [over multiple hops] that's been available only in wired networks until today.
The document discusses Variable Coding and Modulation (VCM) in DVB-S2 satellite transmissions. VCM allows a single transponder to transmit multiple transport streams, with each stream using a different modulation type and forward error correction rate. This makes it possible to provide stronger error correction for basic channels while using weaker correction for premium channels. A VCM-compatible tuner can determine the coding rates being used and properly demodulate the different streams. This provides more flexible use of satellite bandwidth than conventional systems with a single coding scheme per transponder.
The document discusses Variable Coding and Modulation (VCM) tuners for satellite receivers. VCM allows a transponder to transmit multiple transport streams, with each stream able to use different error correction coding rates. This provides flexibility to prioritize streams, such as transmitting premium HD channels with weaker error correction only in the center of the satellite footprint. A VCM tuner can receive these signals by determining the coding rates of each stream. The tuner's architecture is similar to conventional tuners but includes additional components to process the multiple streams and their varying coding rates transmitted by VCM.
Satellite IP Trunking networks provide local networks with access to the internet (or any other type of network) from a remote access point to the backbone.

Welcome to International Journal of Engineering Research and Development (IJERD)IJERD Editor
This paper analyzes the performance of 16QAM and 64QAM modulation techniques in a MIMO Rician channel for a WCDMA system. The performance is evaluated using two error correction coding schemes - BCH encoding and Reed Solomon encoding. Simulation results show that 64QAM has a lower bit error rate than 16QAM for both encoding schemes as the signal to noise ratio increases from 0-10dB. BCH encoding is also found to provide better performance than Reed Solomon encoding for both modulation techniques in the MIMO Rician fading channel. Overall, 64QAM modulation with BCH encoding provides the best performance for the WCDMA system.

Hostless : Simple Connectivity For WiMax DevicesGreen Packet
4G wireless nomadic devices in the form of USB dongles and Pocket modems are fast becoming the preferred devices for wireless broadband access amongst 4G operators. Due to benefits of lower cost and smaller form factor, 4G wireless nomadic devices now account for 39%* of total WiMAX devices shipped in 2010, and this tendency is set to continuously increase in the coming years as 4G becomes pervasive.
Greenpacket 4G nomadic devices now provides an option to allow the use of generic Virtual Ethernet link protocol (USB CDC or RNDIS) to connect with these external host controllers running on any operating systems as an alternative to the traditional CU approach. We call this feature “Hostless” connectivity. Very similar to how an end-user would connect a USB memory stick, this new Hostless feature can be visualized as a generic version of a CU, borrowing the native USB Ethernet driver and management features from the host operating system.
This paper explains the implementation scenarios of both the CU approach and Hostless approach to match specific needs. We will then dive in detail to understand the concept background of Hostless by looking at the system architecture and describing the step-by-step of how Hostless works within the host terminal from an end user perspective.

Policy-based controls that provide visibility into usage patterns can help operators implement tiered pricing plans tailored to different subscriber profiles and applications in order to better monetize data usage.
The document proposes LTE Release 10 and beyond (LTE-Advanced) as a candidate radio interface technology for IMT-Advanced. It provides an overview of 3GPP standardization activities, including LTE Release 8 which focused on improving spectral efficiency and reducing latency.

Self Service Customer Care For Next Generation NetworksGreen Packet
Smartphone devices have dramatically changed the way consumers consume data. The need to be connected anywhere and anytime is driving service providers to put focus into customer experience to grow customers, build loyalty and drive profits through new services. As a result, the expectations of service experience from the end-user are heightened and cannot be underestimated.
Service providers are under pressure to deliver customer experience that separates them from the competition, while at the same time trying to delicately balance their revenues and managing costs for near term gain and longer term success. In this paper, we outline the scale of issues faced in mobile device and service care that impacts both service providers and end-users beyond connectivity. With a broad range of services and wide variety of applications, the smartphone requires more complexity to handle a multitude of firmware and software configurations which legacy CRM systems are inadequate to deal with today’s customers.
Remote device support and service care is a key component to tackle the demands of escalating costs in customer care. Service providers are seeking integration onto backend systems without incurring heavy infrastructure changes and ensure the best fit into the existing operations through automated and proactive customer care mechanisms to ensure service excellence and thus prevent service quality degradation.

It analyzes a reference network delivering symmetrical and asymmetrical services from a hub in Sudan to 10 remote sites in Africa. Using conventional fixed modulation, a minimum of 3 transponders is needed for symmetrical services but asymmetrical services require too much bandwidth to fit in two transponders. The paper will evaluate if ACM or signal cancellation can provide a more efficient implementation.

White Paper-Evolution from 10Gbps to 100Gbps for a Metro Network-hsSusmita Adhikari Joshi
This document discusses the evolution from 10G to 100G networks for metro applications. It describes how 100G technology can complement existing 10G infrastructure by utilizing unused wavelengths on fibers. A key consideration is maintaining economic viability while providing greater bandwidth efficiency. Direct detection is seen as more suitable than coherent detection for metro due to lower cost and complexity. The document outlines various technological requirements for a 100G network such as 100G transceivers, DWDM multiplexers, optical amplifiers, dispersion compensation, and FEC. It provides an example architecture for upgrading an existing 10G system to incorporate 100G services over longer distances.
Rethinking Mobile Backhaul Offering for a Fixed Operator like ColtValéry Augais
Colt is considering expanding into mobile backhaul services to support the growing need for small cell connectivity. Small cells will be critical for meeting bandwidth demands but will require dense deployment and new backhaul solutions. Colt's fiber network across Europe provides an opportunity to offer neutral host small cell sites and backhaul. However, backhaul design is complicated by varying mobile network requirements around connectivity type, latency, security, synchronization and evolving technologies like Cloud RAN. Colt must determine the best approach to address this diversity of needs.

The document discusses the shift towards using coherent optical technology at the network edge. It argues that 100G QSFP28 ports using coherent 100ZR technology will dominate the optical edge in the coming years. This will allow for longer transmission reaches of over 300km compared to traditional direct detection. Key advantages of coherent 100ZR include lower power consumption of 5W or less in a QSFP28 form factor, simplified deployment without manual tuning, and compatibility with existing network infrastructure. The technology could enable seamless upgrades to 100G speeds at aggregation points across access networks.
Microwave backhaul plays an important role in providing a good user experience and overall network performance. The backhaul capacity needed per base station differs substantially, depending on target data rates and population density.
Microwave backhaul technology is able to handle 100 percent of all radio access sites’ capacity needs. This is true for today as well as in 2020, when it will evolve to support multi-gigabit capacities in traditional frequency bands and beyond 10 gigabits in the millimeter wave.

This document discusses Wi-Fi offload strategies for mobile carriers. It outlines a 3 step approach: 1) View Wi-Fi offload as a long term strategy for incremental returns rather than just short term cost savings. 2) Scale carrier Wi-Fi networks and shape user behavior to drive more usage. 3) Consider the implications of Wi-Fi for mobility and roaming. It also discusses the need to harmonize Wi-Fi and mobile networks to provide a seamless experience, and factors influencing whether simply providing ubiquitous Wi-Fi access is sufficient.
This whitepaper discusses the next decade for WiMAX technology. It summarizes that WiMAX has evolved through several releases to support increased mobility and integration with LTE. While LTE deployment has increased, WiMAX still has applications in fixed wireless, rural broadband, and vertical industries. The whitepaper outlines ITU's vision for 4G networks, including seamless handovers between different wireless technologies to provide "always best connected" service to users across various network layers from personal to cellular networks.
WiFi Offload Strategy for Telcos-OperatorsGreen Packet
Given the increase in the number of permutations of device and content available out there, a move towards web-based cloud solutions will inevitably form the need for more mobility and efficiency in delivery. This paper will discuss the implications of the emergence of multifunction, multi-radio systems and multiplatform application and services that are driving forward seamless mobility in the pretext of “now” that allows users to transparently access network connections and ensure session persistence across varied connections for consistent experience together.
The document discusses how carriers can change their mobile broadband strategies to better address challenges from increasing data usage and over-the-top players. It recommends that carriers gain a deeper understanding of how customers use their smartphones and data to help differentiate services and optimize networks. Carriers should also explore managed service models to partner with third-party content and app providers to stimulate mobile data usage rather than trying to be direct content providers themselves. Implementing end-to-end policy control and quality of service management can help carriers enable popular apps and deliver new service offerings.
The ability to use voice, mobile apps, SMS, email, websites, chat, video, and social media through a single device is forcing operators to rethink their mobile strategies in the form of offload. With the increased data usage, operator networks become increasingly congested. As such, a smart and dynamic connected interaction is necessary to allow better traffic management with particular capabilities of the device with which it is characterized.
In this paper, we will examine how dynamic data offloading with 3GPP based Access Network Discovery Selection Function (ANDSF) plays its role in the implementation of selective offloading. ANDSF as specified in 3GPP standards describes how the inter-system mobility between 3GPP systems and non-3GPP systems (WLAN, WiMAX, CDMA) policies and priorities can control the conditions for which a device connects to which wireless network. As mobility is becoming a mainstream for customer engagement, operators must ensure contextual continuity is preserved through an integrated approach.
This document discusses direct internet offload as a way for mobile carriers to offload data traffic from their cellular networks onto Wi-Fi networks. It describes direct internet offload as allowing data traffic to bypass the carrier's core network and be passed directly to the internet. The document discusses stakeholders in offload strategies and how understanding user behavior can help carriers implement offload. It also provides recommendations for carriers to start direct internet offload, such as building out their own carrier Wi-Fi networks or partnering with Wi-Fi aggregators.
Data offload survival guide, a phased approach – simple offload for phase 1Green Packet

Wi-Fi New Service Models For Next Generation NetworksGreen Packet
In this new era of explosive mobile data growth, rapid rise in mobile broadband services and rich digital content are contributing to unprecedented level of stress on mobile networks. Operators are feeling the pinch on their business models with the arrival of smart devices, leaving them in anxiety and unable to respond to the deluge of data.
As a measure to reduce congestion on their network, several tier 1 operators have discontinued unlimited data plans and launched tiered plans to ensure network performance. At the same time, operators do not want to risk losing a significant growing market of smartphone users that are looking for value added services. It is a challenge for operators to sustain the wave of data, let alone address the dwindling ARPU as the demand of data is outstripping the rate of supply.
The following section of this paper describes the possible options that operators can embrace to overcome the capacity crunch through innovative service models, the impact of Wi-Fi on delivering the right service experience and how emerging technology is pushing further the expectations of “big data”.

Pocket Modem : Bringing Forth The Synergy Between WiFi and WiMAXGreen Packet
WiFi has changed the way people connect today and has become the defacto wireless technology on most consumer electronic devices. Where WiFi faces limitation, particularly in terms of fixed usage, Mobile WiMAX complements through its mobility advantage.
This paper focuses on the portable Pocket Modem, a device that leverages on the synergy offered by WiMAX and WiFi. It examines how this synergy benefits users and provides a better connectivity experience.
Dynamic Data Offloading : Connect Intelligently With ANDSFGreen Packet
The arrival of varied smartphones and devices has inevitably encouraged greater data consumption.
Users are now more sophisticated and demand nothing less than best network performance. Smartphone generally accounts for higher ARPU and represents potential new revenue streams for enabling quad play services. Operators are aggressively addressing these challenges and improving the quality of their solution to retain existing customers and offering better service experience to build loyalty.
WiFi adoption as data offloading is gaining momentum as it improves user experience while lowering the cost of service providers. Correctly implemented, it can ease up to 20% of traffic with substantial impact of freeing up the spectrum and load balancing. Offloading data to WiFi hotspots is economically attractive, because many carriers already operate a substantial number of hotspots.
In this paper, we will examine how dynamic data offloading can be further optimized with 3GPP based Access Network Discovery Selection Function (ANDSF). ANDSF describes how the inter-system mobility between 3GPP systems and non-3GPP systems (ie: WLAN, WiMAX, CDMA) policies and priorities can control the conditions for which a device (UE) connects to which wireless network.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

2. Abstract
Wireless broadband operators constantly face challenges of balancing the economics to deploy a robust and reliable
wireless broadband service in suburban-rural areas or at cell-edges. Till to date, a large portion of these areas still
remains hugely underserved or receiving unreliable coverage. Most available studies have shown that WiMAX is indeed
an ideal technology candidate not only for a suburban-rural deployment, but as a wireless broadband technology on an
overall, with most of the studies focusing on infrastructure performance.
This paper in retrospect functions to further solidify the technological advantage of WiMAX, where we explore and proof
the concept of suburban-rural deployment through the optimal pairing of a proper CPE strategy. We will show that the
best solution for suburban-rural area and cell-edge performance can be extended four times through deployment via
outdoor CPEs.
This paper explores deep into the technical and implementation advantages of an outdoor CPE solution, including the
concept of antenna gain, transmission power, integrated POE design and environment-proof enclosure; and the effective
advantage of Line of Sight performance and decreased penetration loss amongst other features of an outdoor CPE. We
will also explore the misconception behind the high incremental cost, difficulty of engineering installation and service
challenges in operations with the implementation of an outdoor CPE which has been the lead culprit towards the low
adoption of this CPE strategy. Greenpacket will share three reference cases where deployment through the OX series
outdoor CPE has shown great success in Australia, Africa and Haiti, from a performance and business implementation
perspective.

3. Introduction
One major challenge for wireless broadband operators is to successfully deploy in a suburban-rural morphology. This
challenge is inherent with disregard of the type of wireless technologies implemented, be it through WiMAX, Satellite, 3G,
CDMA and similarly in the future, with LTE. In our previous white paper “Improving Indoor Coverage: How WiMAX
Modems can Play a Major Role in the Subsystem” (WPWIC10), we have described technologies to improve user
experience when they are farther away from the base station, or in the cell-edge area. We can see that in general,
cell-edge represents the area where poor consistency in connectivity is prevalent, with typical modulation being QPSK
where cell-edge users generally experience low and in many cases, inconsistent throughput speeds.

Figure 1 : UL and DL Modulation Relative to Cell Radius
The figure below represents a typical wireless cell that has a cell-center with radius ‘r’ and cell edge with a radius of ‘2r’.
Tabulating the coverage area, the cell-edge would give us an area of coverage equivalent to 4πr², while the cell-center is
only πr². Showing the distinct differences in coverage area achieved between the cell-edge and cell-center. This direct
difference implies that the efficiency of spectrum utilization by the base station is not able to achieve its intended
maximum coverage and capacity capability unless higher modulation scheme can be extended further into the cell-edge
coverage area; without which, a decent robust connectivity is next to impossible by just relying on the base station itself.

4. WiMAX As The Best Solution With Outdoor CPE
Challenges For Rural Broadband Deployment
Broadband penetration in rural areas across the world has lagged far behind than that in urban areas, both in developed
countries as well as in developing countries. This is mainly due to multiple reasons which make providing coverage in
these areas economically non-viable. The main reasons for this low penetration lie within the following TOP 3
roadblocks:
• As population density in rural areas is relatively low, setting up and maintaining copper or fiber lines to provide
broadband service across the “last mile” incurs high costs for Internet Service Providers (ISPs)
• Capacity on the backhaul or the “middle mile” from the ISP to the Internet backbone is often very limited and
expensive as it is provided over facilities designed for voice telephony or cable television
• The difference in per capita income between rural areas and urban regions means that broadband services need to
be offered at a lower-price point in the rural areas in order to gain customer adoption.
This combination of high CAPEX/OPEX and low Average Revenue per User (ARPU) has traditionally made the rural
broadband market less lucrative for service providers, but the advent of new high speed mobile broadband technologies
such as WiMAX has rapidly changed the situation.

5. WiMAX As The Ideal Solution For Rural Broadband Deployments
As operators around the world evaluate multiple technologies for rural broadband deployments, WiMAX is emerging as
the de-facto standard. The advantages offered by WiMAX have time and again proven its commercial viability, among
others:
• Infrastructure Effectiveness: WiMAX offers a highly cost effective solution to address the rural broadband conundrum
as physical infrastructure need not be rolled out to individual customer premises on the last mile. This significantly
reduces the overall cost and the time-to-market in deploying the network.
• Flexible Network Deployment: WiMAX allows operators to surgically choose deployment options and focus on
specific areas where there is strong demand.
• High Data Throughput: 802.16e has reached a stage of technology and standards maturity with field proven results
that shows data throughput of over 40Mbps (@10MHz channel bandwidth).
• Spectrum Concerns: WiMAX spectrum has typically been less expensive worldwide as compared to 3G licenses.
Additionally, with mobile WiMAX being on licensed band, operators can deploy rural broadband networks with no
spectrum-related concerns.
The largest challenge facing operators in deploying a suburban/rural service is to create a balanced business case that
allows them to maximize the access infrastructure capability from a coverage and capacity perspective and at the same
time to deliver a robust and reliable service with a positive revenue return. Greenpacket believes that this can be realized
effectively if ‘Line Of Sight’ (LOS) can be achieved through the pairing of Outdoor CPE to the network, where we will
investigate the technology, performance and reveal a detailed deep dive reference case study based on a suburban/rural
environment profile.

6. Advantages Of Outdoor CPE
The right CPE strategy for cell-edge and suburban/rural area is to deploy Outdoor CPE, and from our experience,
outdoor CPE have the following advantages.
i. Improved Uplink Technologies
ii. High Transmission Power And High Gain Directional Antenna
iii. Zero Penetration Loss
iv. Further Improvements Due To Line Of Sight
v. When Compared To External Antenna Option, Minimal Cable Loss
vi. Environmentally Robust
vii. Easy Installation
viii. Plug And Play
(i) Improved Uplink Technologies
We have stated a comprehensive analysis of the importance of uplink technologies in our previous white paper “A
Practical Approach to Improve WiMAX Indoor Coverage.” Here, we briefly describe the most important technology Dual
transmitter (2TX) which is implemented in our OX series Outdoor CPE.
Dual Transmitter (2Tx) (CDD)
The simplest Dual Transmitter technology employs Cyclic Delay Diversity (CDD) algorithm and signals are transmitted via
a single data stream through two antennas and two power amplifiers – hence, both antennas are switched on and used
for transmission. The combined power from two PAs provides approximately an additional perceived 3dB gain with
potentially lower power consumption (if PA’s are tuned to a lower power). This arrangement improves uplink performance
and lengthens coverage through better signal strength; however, it increases the cost of the modem as more
components are used.
Dual Transmitter (2Tx) STC Matrix (Uplink MIMO A)
The second generation Dual Transmitter technology further employs Space Time Coding signaling algorithm (Uplink
MIMO A) instead of just (CDD) algorithm as previously mentioned. However, in order to support this new algorithm, base
stations need to be upgraded to support WiMAX R1.5. The hardware implementation is the same as Dual Transmitter
(CDD) where transmission is conducted through two antennas and two power amplifiers. The combined power from two
PAs provides approximately an additional perceived 4dB gain, which is better than the Dual Transmitter (CDD).

7. (ii) High Transmission Power And High Gain Directional Antenna
Comparatively, Outdoor CPEs are designed with higher maximum transmit EIRP. Greenpacket OX series Outdoor CPE
has a 14dBi antenna, Dual transmitters (2Tx) with a combined Tx power rated at 27dBm, thus a maximum transmit EIRP
equivalent to 41dBm, making it the most powerful mobile WiMAX CPE in the market today. Directional antenna is
conventionally implemented to optimize the antenna performance specifically aligned to face towards the base station.
Different from an indoor or USB based device, operator will normally assign service engineers to the premise where
installation is based on the optimum facing direction and upon locating it, the outdoor antenna is locked into place.
Figure 3 shows a sample antenna pattern for the 2.5GHz model. The diagram shows a concentrated RF energy radiated
in a single direction (+- 10 degrees within the pink line). This specific radiation pattern plays the highest role of effectively
increasing the coverage area.

APPLICATION NOTE
8. (iii) Zero Penetration Loss
Throughout our deployment experience, depending on the depth and material of the building, Glass windows and
concrete walls induces a 6dB and 12dB penetration loss respectively where the implementation through indoor CPEs
will normally endure. An Outdoor CPE, being placed normally on the roof of a specific building has the advantage of
being subjected to zero penetration loss, even without line-of-sight (LOS).
Figure 5: Frequency Vs Depth of penetration (Pd) for representative profiles of clay soils of pune at different soil moisture
conditions (weight %)
(iv) Further Improvements With Line Of Sight (LOS)
The key advantage for Outdoor CPE is that it can easily achieve Line of Sight (LOS) with proper mounting. Having
achieved Line of Sight (LOS), there is no longer a multi-path problem and we can ensure optimal RF path between the
CPE and the base station. Figure 6 shows how Line of Sight can be achieved by moving the CPE above the roof with a
pole.

In addition, studies show that for a full featured base station. To achieve the same transmission data rate of 11Mbps,
LOS cell radius can be as far as 30km, while Non Line of Sight (NLOS) cell radius is only limited to 4km. This accounts
for five times the radius or about 25 times more coverage area for the same base station. LOS is a very critical
06
factor that affects the performance of the network, where an Outdoor CPE is proven to be the ideal solutions
to achieve LOS.

(v) Outdoor CPE VS Indoor CPE + External Antenna: Minimal Cable Loss
Another common solution to achieve LOS performance is to use outdoor external antenna to connect to an indoor CPE.
However, using external antenna introduces cable losses. For example, we can see in the below diagram, a typical cable
used for external antenna is RG316, which introduces about 1.5dB loss per meter length. Therefore, for an outdoor
extension of 10m, this contributes to 15dB loss, which has similar magnitude as the typical outdoor external Antenna
gain. This limitation is not absolute, where external antenna solutions with super high gain (greater than 15dBi) and super
low loss cable (less than 0.5dB/m) can be found, the question is however extended to economic sense of forming a
realistic solution rather than the best solution.

11. Uncover The Myth about Outdoor CPE
There exist general misconceptions about outdoor CPE implementation in terms of cost, having extreme restriction on
being heavy, performing unreliably under changing weather conditions, and extremely difficult to install and service.
New advancement on design and architecture has changed all this, Greenpacket’s OX series outdoor CPE is an example
where cost is effectively affordable, weighing in at less than 2kg, flexibly mountable on a wall or pole or roof edge and
capable of enduring temperatures between - 40°C ~ 60°C while in operations.
Most importantly, OX series enclosure is certified to be IP67 compliant which comes with a protection against the effects
of immersion in water up to depth of 1 meter. POE (Power over Ethernet) cable is also an important feature which
ensures that only a single cable (RJ45) is stretched from the outdoor unit (ODU) directly indoors to the end user, where
both the power and data is carried.
(i) Environmentally Robust
In addition, OX series outdoor CPE is equipped with a robust mounting kit which has been certified to withstand severe
windward and crosswinds. Figure 8 show the test result for OX series outdoor CPE withstanding hurricane rated winds
(windward/crosswind under 60m/s for 10 minutes, Beauford Wind Force Scale 17)

13. The Rural Leapfrog – ENDING THE WAIT FOR RURAL
CONNECTIVITY
Verifying It On The Field
Understanding the concept and technological advantage of mobile WiMAX coupled with the service offering via an
Outdoor Modem validates it as a viable solution option for rural connectivity. The bigger question remains on the
performance capability of the WiMAX outdoor modem when deployed in a commercial field that is subjected to
subscriber loading and the environmental uncertainties knowing historically the inherent limitation of implementation via
a wireless technology.
Vivid Wireless, is the first WISP to launch a mobile WiMAX network in Australia has had a successful service uptake since
its launch in April 2010 covering the urban and suburban areas in cities of Perth, Sydney and Melbourne via Indoor IADs
and USB modem. Looking to extend its service coverage to the fringing suburban and semi-rural areas within the city,
Vivid Wireless conducted a citywide evaluation to benchmark the performance of the OX outdoor modem. Vivid Wireless
wanted the performance test to be conducted on its commercially live network to ensure that the end results obtained
is strictly similar to the end user experience. Choosing to compare it against the current commercially offered Green
Packet high gain DX Indoor IAD, Vivid Wireless has the objective:-
1. To ensuring that the OX meets the technical specification as stated in its product datasheet.
2. To record the additional gain in coverage, and
3. To record the throughput speeds experienced

15. Reaching Within Remote Africa
Direct-on-PC, a the leading operator in Nigeria has been deploying mobile WiMAX under the service name of Unwired
by extending its wireless broadband voice and data services covering sub-urban and rural developing communities in
selective areas of Lagos, Abuja and Port-Harcourt as a complimentary broadband access network to their existing VSAT
and fixed wireless networks. The flexibility of mobile WiMAX has allowed the operator to grow its service coverage area
flexibly as service demand grows.
The strategy of service implementation via outdoor based CPE creates the best service advantage as it allows
maximization of coverage making the service robust and reliable, perfect to the harsh conditions of the West African
nation.
With mobile WiMAX having the capacity efficiency that is 10x higher with an upfront subscriber acquisition cost that is
1/5 of current satellite network, the business case of providing affordable voice and broadband service is achievable. This
has created confidence that the 4G network plans is set to lay the foundation for growth, both for the company and to
the development of the underserved market.
Bringing Broadband To The Remote Islands
The islands of the Caribbean are a well known holiday destination with a developing community and economy. Providing
broadband services in islands with harsh environmental terrain has always been a challenge to service providers.
Digicel International has been the champion serving over 11 million customers across 32 markets mainly on the islands
of the Caribbean and the Pacific. Having launched mobile WiMAX in Haiti, Digicel has had a great success with its
pay-as-you surf mobile WiMAX services in suburban areas of Haiti currently providing robust fast broadband services
through Greenpacket indoor and USB based devices.
Looking to extend the services offering in rural and remote areas, with the service quality having similar robustness is
something that Digicel insist to maintain, in order to achieve this while not having to incur huge incremental CAPEX
investment by deploying additional infrastructure to these subscribers located mainly in fringing cell edge of the network.
The outdoor modem was evaluated and results has proved to be the perfect solution extending the coverage within a
healthy modulation scheme to achieve broadband speeds and consistent service.
Even with a higher subscriber acquisition cost via the outdoor modem implementation, the huge CAPEX/OPEX savings
from infrastructure spending allows Digicel to scale the deployment needs with the number of subscription growth.
