Ericsson Technology Review – Microwave backhaul gets a boost with multibandEricsson
With the exception of Northeast Asia, 65 percent of all cell sites will be connected to the rest of the network using microwave backhaul technology by 2020. Between now and then, the performance of microwave backhaul will continue to improve, supporting growing capacity needs through technology evolution and more efficient use of spectrum. So as the dominant backhaul media in modern networks, the ability of microwave to carry traffic plays a significant role in providing good mobile network performance.
Technology evolution, increased mobility, and massive digitalization continue to place ever more demanding performance requirements on networks. The constant pressure to increase performance translates into a need for more spectrum, and more efficient use of it – not just when it comes to radio access, but for microwave backhaul as well.
But spectrum is a finite natural resource, so technology developments not only need to be able to make use of higher frequencies, they also need to unleash the potential of all the untapped spectrum that exists.
Radio-link bonding is a well-established method for enhancing peak capacity, enabling multiple radio carriers to be aggregated into a single virtual one. So far, developments have focused on bonding carriers within the same frequency band. The multiband booster concept, however, uses radio-link bonding to aggregate carriers in different frequency bands, enabling the full spectrum potential to be unleashed.

The effects of rain fade on millimetre wave channel in tropical climatejournalBEEI
The main objective of this paper to determine multipath and time-varying channel behaviour of short-terrestrial millimetre-wave point-to-point radio links. In an attempt to invigorate the impact of rain attenuation on mm-wave channel parameters such as the RMS delay spread, path loss received power strength and Rician distribution with a K factor. A brief analysis of rain fading was presented based on the simultaneous measurement of one-minute rain rate and its effects on a short experimental link of 38 GHz. Rain fade average is observed as high as 16 dB for 300 m path at about 125 mm/hr rain intensity. The statistical spatial channel mode (SSCM) simulation software was utilized for an operating frequency of 38 GHz. To generate of power delay profile (PDP). For both omnidirectional and directional antenna. The RMS delay spread and path loss has been estimated using the environmental parameters of Kuala Lumpur city which illustrates the theoretical performances of 5G in Malaysia. It is observed that RMS delay spread, path loss received power strength and K factor effected dramatically by rain fade. (SSCM) simulation software has to be modified to consider rain fade dynamic characteristics to achieve ultra-reliability requirements of outdoor applications in the tropical regions. This study is important for understanding signal propagation phenomena in short distance and enabling the utilization of the millimetre wave band for an urban micro-cellular environment for 5G communication system.
Recently Qualcomm announced its 5G (the fifth generation mobile communications) vision. 3GPP is going to finalize the 5G standard by 2018. 5G is scheduled to launch in around early 2020s. Even if it is not determined yet regarding the standard technology details, many researchers expect that 5G will transfer 1000 times more data, and thus, can connect billions of IoT (Internet of Things) devices at the same time. Key candidate technologies that enable 5G to support IoT devices connection are millimeter wave/MIMO (multiple input and multiple output) technology, cloud RAN/network function virtualization (NFV)/ software defined network (SDN), ultra dense network (UDN), low latency network and RSMA (Reservation multiple access)/FDR (full-duplex relaying). Following Qualcomm patents illustrate some examples of the 5G standard technology R&D of Qualcomm.

Land mobile communication is burdened with typical propagation constraints due to the channel characteristics in radio systems.Also,the propagation characteristics vary form place to place and also as the mobile unit moves,from time to time.Hence,the tramsmission path between transmitter and receiver varies from simple direct LOS to the one which is severely obstructed by buildings,foliage and terrain.Multipath propagation and shadow fading effects affect the signal strength of an arbitrary Transmitter-Receiver due to the rapid fluctuations in the phase and amplitude of signal which also determines the average power over an area of tens or hundreds of meters.Shadowing introduces additional fluctuations,so the received local mean power varies around the area –mean.The present section deals with the performance analysis of fifth generation wireless cognitive radio network on the basis of signal and interference level based k coverage probability under the shadow fading effects.

LTE & Wi-Fi: Options for Uniting Them for a Better User ExperienceAricent
Most national governments consider the radio spectrum a valuable national resource and heavily regulate its commercial use. Governments typically auction off licenses for the right to transmit over a portion of the spectrum, which can be very expensive. The traditional business model for cellular
carriers is based on access to this licensed business has coalesced worldwide around a single 4th generation (4G) radio technology standard called Long Term Evolution, commonly referred to as LTE.
LTE & Wi-Fi: Options for Uniting Them for a Better User Experience Aricent
All the options that involve Wi-Fi in the unlicensed spectrum may eventually be supported by handsets through software updates, making them available to carriers on equal terms. In the meantime, however, Aricent believes LWA is a technology that
has great potential and capabilities that could make it the eventual winner.
Evaluation of Percentage Capacity Loss on LTE Network Caused by Intermodulati...Onyebuchi nosiri
Abstract- The paper evaluates the effects of third order Intermodulation Distortion (IMD3) on the Long Term Evolution (LTE) receiver due to coexistence between LTE and GSM networks. Amongst the various existing IMD orders which include first order, second order, third order, fifth order and seventh order. Third order is known to have the greatest distortion effects on a receiver due to its strength and its proximity to the frequency band of interest. It occurs as a result of the non-linear behavior of components or circuit at both the transmitter and receiver ends of wireless communication networks. IMD has potential negative effects on a victim receiver which majorly leads to increase in noise floor level and system capacity degradation. Deterministic approach was implemented in the work assuming worst case scenario. MATLAB software simulation was deployed to evaluate the capacity loss at the receiver end relative to a range of distances apart. Results obtained showed severe uplink capacity degradation when VISAFONE LTE network was interfered by INTERCELLULAR LTE downlink and ETISALAT GSM uplink. Various distances ranging from 500m to 3000m were varied between the ETISALAT GSM network and the VISAFONE LTE network. The results obtained showed that at 500 meters, the percentage capacity degradation was as high as 80. The least percentage capacity loss was obtained as 5.97 at 3000 meters.

The project manages to derive the range of operation of a user in interference based scenarios between Femtocells and Macrocells, in terms of Signal to Noise and Interference ratios. The simulation was carried out for both the uplink and the downlink scenario. It could be successfully concluded that the environment that the user is in plays an important part in performance evaluation of the user.
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.

problema de congestionamiento de las redes móviles y la falta de cobertura en las zonas con una alta
densidad de tráfico.
Durante la exposición, la empresa realizó además una prueba de servicios de voz sobre LTE (VoLTE).
La demostración se realizó en la banda de 2,6 GHz y con equipos Ericsson.
Telefónica señaló que el servicio de voz sobre LTE supone un 40 por ciento de mejora en la calidad de
voz y logra establecer una conexión 20 veces más rápida que una llamada 3G. Además, permite
combinarse con servicios de voz de alta definición, ubicación y Rich Communication Suit (RCS).
Asimismo, afirmó que la solución permite priorizar unas secuencias de datos sobre otras, ofreciendo un
servicio de alta calidad continuo y destacó que VoLTE emplea una única solución de radio en el
dispositivo del cliente, permitiendo mantener las llamadas sin interrupciones cuando un cliente pasa de
una zona de cobertura LTE a otra sin ella.

2.- Penetration loss in LTE.
Penetration loss in LTE indicates the fading of radio signals from an indoor terminal to a base station due
to obstruction by a building. For an indoor receiver to maintain normal communications, the signal must
be sufficiently strong. The indoor receiver obtains radio signals in the following scenarios:
2. fam’s teleco news (Año3-Nº12/Marzo 2013) 2/12
• The indoor receiver obtains signals from an outdoor transmitter.
• The transmitter and receiver are located in a same building. See Figure below
The link budget is only concerned with the scenario in which an outdoor transmitter is used and the
signals penetrate only one wall.
The propagation modes of electromagnetic waves are as follows: direct radiation, inverse radiation,
diffraction, penetration, and scattering.
In areas where no indoor distributed system is deployed, electromagnetic wave signals are obtained
through diffraction and scattering. Therefore, the indoor Penetration loss in LTE is related to the incident
angle, building materials, terrain, and working frequency. Table below lists the penetration losses
associated with typical buildings.
Typical building penetration losses
In the link budget, Penetration loss in LTE values depend on the coverage scenario. Therefore, coverage
target areas are classified into densely populated urban areas, common urban areas, suburban areas,
rural areas, and highways. Table below lists the area classification principles.
Principles for classifying coverage scenarios
The building Penetration loss in LTE ranges from 5 dB to 40 dB. In link budget, if no actual test data in the
target area is available, an assumed Penetration loss in LTE value must be used. The final assumption is
also highly dependent on local customer requirement.
For example in sophisticated Asian Metropolis like Hong Kong, Singapore and Shanghai, the indoor
coverage expectation will be very high, hence requiring a high Penetration loss in LTE provisioning. On
the other hand, in less developed market such as Africa and Latin America, customer expectation is lower
so the Penetration loss in LTE requirement can be reduced to reduce overall cost involved.
During network planning, if no actual field testing data is available, refer to the Penetration loss in LTE
values listed in Table below.

3.- Antenna Implants- Possible Future Trends.
Over the past two decades, the world has been able to benefit from its significant wealth in knowledge
relating to telecommunications engineering. During this time, there has been an exponential growth in the
field of mobile communications, proving beyond doubt that people love to talk. Coincident with this
success there has been a massive increase in healthcare provision in the world combined with an
associated revolution in how treatment is offered to the patient. The simplicity and utility of technologies
like Global System for Mobile Communications (GSM) with voice, data, 3G with streaming video and 4G
with its superior resource allocation all offer much to healthcare, particularly for non-secure medical
telemetry. Discussed here is the future concept of 4G systems implanted into the body with bidirectional
link to the cellular network. This is different from current systems that communicate with implanted
devices over short range links (<410 m).
4. fam’s teleco news (Año3-Nº12/Marzo 2013) 4/12
Given the right safeguards for implanted mobile phone technology, it would for example be possible to
measure the properties of a heart attack in real time and perhaps monitor the effects of treatment
subsequent to the event, whilst allowing the patient freedom of movement. What would be needed would
be a system that could be implanted into a patient for short periods of time (perhaps several weeks) that
could be used to transmit data out of the body and to a medical expert. In this context such a system
would use data rather than voice, be non-real time with low isochronous application usage.
What is envisaged might be low SAR (Specific Absorption Rate) flexible antennas just beneath the skin
surface for use with cellular systems and their vast networks of base stations. Such a system would
comprise a small telecommunications module with integrated micro controller and power supply attached
by cable to an antenna. The module, its battery and its associated sensors would lie inside the body. To
minimize SAR the antenna would lie as close to the outside of the body as practical but not outside the
skin. The system would be encapsulated and screened to reduce energy interactions with tissue. From
the point of view of avoiding infection the proposal to have the whole system inside the body’s protective
skin is of clear benefit. By not breaching the skin complications arising from infection; hygiene and painful
snagging would be avoided. Furthermore such in-body systems would be invisible to other people and
may allow patients an extended freedom of movement and much more privacy. All of the components
except the antenna are state-of-the-art. In considering the size of such antennas we are helped a great

deal by the permittivity of the surrounding tissue which is generally high. Therefore, such antennas would
tend to be much smaller than their free-space counterparts (for example about 25mm long for a half wave
dipole at 900 MHz).
It can be shown, for example with LTE wireless communications, that it would not currently be a problem
sending 4G signals to a modem implanted inside a body cavity. However, because of the very strict
legacy limits related to medical implants, the tricky part of such a system would be how to get 4G signals
out of the body to a base station without exceeding SAR limits within the body. For a mobile handset
power levels from a handset are limited to 2 Watts but are typically around 0.6 Watts split across several
channels. However for medical implants the limit is 25 micro-Watts.
The standards germane to this discussion are the Medical Device Radiocommunications Service
(MedRadio) and the Wireless Medical Telemetry Service (WMTS). MedRadio has a spectrum between
401 and 457 MHz. The more common devices realized have been implanted cardiac pacemakers and
defibrillators, and neuromuscular stimulators for physical mobility. WMTS has spectrum at around 0.6
GHz and 1.4 GHz and has been used for sending data about such things as pulse and respiration rates to
close in receiving stations. A typical application would be a cardiac monitor wirelessly linked to a nurse’s
station for post operative care.
The ability to communicate with an implant over a high bandwidth link would facilitate many new
applications and enhance existing applications such as pacemakers, implantable cardioverter
defibrillators, neuro-stimulators, hearing aids, robotic prostheses, artificial eyes, brain pacemakers to
control Parkinsons disease, monitoring of blood glucose levels for diabetic patients, stimulation and
recording of brain and muscle activity, swallowable pills for traversing the gastrointestinal tract and
implantable drug delivery systems.
Implanted medical devices save lives, increase the quality of the user’s life, reduce the number of trips a
patient has to make to a hospital and save billions of dollars in hospital beds, resources and doctors’ time.
Lifesaving implants such as cardiac pacemakers, neuro-stimulators and pumps, have now become
routine and do not attract the negative media attention that normally follows attempts to create so
calledbionic people. The cardiac pacemakers and defibrillators have grown into a multi-billion pound
industry since the first implanted pacemaker in 1958. As implanted antennas are aimed at the same
market, improving the quality of life of severely ill patients or others who are at high risk of illness, it is
expected that it will be well received by both the medical community and patients alike.
After all, antennas are implanted inside the human body as a method of treating tumors using
hyperthermia. Previously, battery power has been a limiting factor. A typical pacemaker uses less than
10mW and the battery lasts 10 years. However, a long range medical biotelemetry system consisting of a
sensor(s), a battery, a 4G communications module and a low power subcutaneous antenna may only
need to be in place for a few weeks.

During the phase of preliminary acceptance before commercial launch, KPIs will be derived from the drive
test analysis and stationary measurements, and this analysis and measurement are on the basis of
cluster which constitutes a group of sites (20-40 sites).
Statistics KPIs are not proposed and measured at this stage as the traffic is insufficient, statistics will not
eligible statistical result without enough samples.
After on-going optimization while the traffic keeps increasing after commercial launch, the final
acceptance of the whole network performance on the basis of statistics will be implemented. However,
the KPI values of statistics probably might not be same with those in drive test due to different
calculations and considerations.
LTE Service KPIs and LTE Network KPIs
The Field Test KPIs into two categories: LTE Service KPIs and LTE Network KPIs.
Service KPIs are the KPIs that are not subject to be effected by cluster tuning and optimization
activities, mainly determined by product performance, configuration and parameter setting, e.g. ping
delay, throughput, etc. I recommend that only one cluster (named pilot cluster) is selected for the
evaluation and acceptance for the Service KPIs, no necessary for repeating the measurement in all
clusters Based on the above reasons, the Service KPIs’ test is suggested to be performed by Stationary
Test (ST) in the area with good RF conditions and close to the cell in order to eliminate the affect of poor
RF or non-equipment factor and the test is proposed to be implemented under the condition of one
serving cell.
LTE Network KPIs , such as Call setup success rate, Call Drop Rate, Handover Success Rate, which is
determined by the radio network environment, planning and optimization capabilities, should be
performed on the Drive Test (DT) routes in rollout clusters.

5.- Carrier Aggregation in LTE-Advanced – whitepaper.
In order to achieve up 1 Gbps peak data rate in future IMT-Advanced mobile systems, Carrier
Aggregation concept has been introduced by the 3GPP in its new LTE-Advanced standards (3GPP
Release 10 onwards). Carrier Aggregation is aimed to support very high data rate transmissions over
wide frequency bandwidth (e.g. up to 100MHz). This paper gives an overview o Carrier Aggregation,
including its types, cell configurations, its need and benefits. This paper also discusses in brief the major
functional changes required in PHY, MAC and RRC or Carrier Aggregation.

4.- LTE KPI Measurement Methodology and Acceptance Procedure.
Here I write in simple word on LTE KPI Measurement Methodology and its Acceptance Procedure. As it’s
for only at network start up stage and now a day worldwide so many operator starts to launch LTE and so
this is the way for them to check of KPI in LTE
LTE KPI Measurement Methodology
The KPIs are formulated to measure the network performance in terms of Accessibility, Integrity, Mobility,
Retainability, and Subscriber perceived quality.
LTE KPIs are mainly classified into 5 classes, which are, Accessibility, Retainability, Mobility, Latency,
and Integrity. The KPI architecture is shown in the following figure.
The above KPI classification fully considers the customer experience and focuses on the Quality of
Experience, providing a wide range of network KPIs to reflect network factors that are relative to the
service quality, using industry standards as reference to define network counters and KPIs.
LTE KPI Acceptance Procedure
LTE network KPI acceptance procedure for the two phases, preliminary acceptance and final acceptance,
are recommended as shown above.
