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:

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.

fam’s teleco news (Año3-Nº12/Marzo 2013) 2/12In 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 lossesIn 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 scenariosThe 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).

fam’s teleco news (Año3-Nº12/Marzo 2013) 3/12

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

fam’s teleco news (Año3-Nº12/Marzo 2013) 4/12system 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.DE: Telecom Insights

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 LTELTE KPI Measurement MethodologyThe 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.

fam’s teleco news (Año3-Nº12/Marzo 2013) 5/12

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 ProcedureLTE network KPI acceptance procedure for the two phases, preliminary acceptance and final acceptance, are recommended as shown above.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 KPIsThe 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-

fam’s teleco news (Año3-Nº12/Marzo 2013) 6/12equipment 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.De: Teletopix.org

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.

6.- Ericsson and Telstra successfully trial 1Tbps optical link. Telstra and Ericsson have successfully conducted the first trial of 1Tbps technology in

Australia over 995km of an existing optical fiber network Ericsson and Telstra test the fastest ever optical connection in Australia Ericsson demonstrates terabit technology leadership by moving ultra-fast transmission

from the lab to verify its functionality in an existing optical networkEricsson announces the successful trial of its 1Tbps (terabit per second) optical transmission equipment over Telstra's fiber optic network. One terabit is equal to 1000 gigabits.The successful test over the 995 kilometer optical link between Sydney and Melbourne in Australia shows it is possible to deploy 1Tbps technology in a real network environment.  Furthermore, when 1Tbps is commercialized, operators will be in a position to deploy it to meet their capacity requirements.Telstra Director Transport & Routing Engineering, David Robertson says: "We are currently upgrading our optical transmission networks with Ericsson's next generation 100Gbps technology and this trial demonstrates that the higher 1Tbps speeds are possible.   "The trial has proven that our existing optical cable plant can support Tbps channels along with 40Gbps and 100Gbps channels simultaneously on the same fibre, verifying that we have the ability to increase capacity on our existing fiber cables when required." Alessandro Pane, Head of Ericsson R&D Optical Transmission, says: "Like so many developed countries, Australia is a very technologically advanced market and Australians are sophisticated users of broadband and mobile technology. In addition, there is widespread smart phone, tablet, IPTV and HDTV take-up. Supporting all these services requires an ever-growing capacity in backhaul and inter-city transmission."Telstra is a key account for Ericsson and we frequently partner to trial new technology and products. This trial provides insights that are valuable to the Australian market and operators worldwide."Ericsson recently announced it will provide Telstra with the SPO 1400, the latest packet optical transport platform (POTP) for the metro and the MHL 3000 for long-haul applications with 100Gbps service support. The trial tested a 1Tbps line card in the MHL 3000.Ericsson's terabit solution, which was used in the trial, has some important advantages: the optical characteristics are software configurable; innovative frequency packing for high spectral efficiency; and advanced forward error correction for superior performance of the communications channelDe: Ericsson Press Releses

9.- Small Cell Forum launches Release One in new programme to drive operator deployments.Release programme provides “all you need to know” to help operators deploy small cells Mobile World Congress, Barcelona – The Small Cell Forum, the independent industry and operator association that supports small cell deployment worldwide, today announced Small Cell Release One. This is the first deliverable in its Release programme, which helps operators by providing all the information they need to successfully launch the technology in one easily digestible package. The theme of Release One is the Home, providing the complete body of work that operators will need to know in order to deploy residential femtocells. Release One also contains significant advanced work on future releases, including enterprise, metro, and rural small cells.Release One is aimed at operators who have waited to deploy residential small cells until the market and technology were proven while also assisting operators planning newer enterprise, metro and rural rollouts. It provides all the business case and technical detail, including recommended equipment specifications for RFPs, together with best practice from the operators which have successfully deployed femtocells in scale. Release One also contains cutting edge information aimed at assisting new enterprise, metro and rural deployments, including two major new whitepapers on backhaul and rural rollouts, addressing concerns widely raised by carriers, as well as an operator agreement on key requirements for public access small cells:• The rural small cell whitepaper finds that the there are no barriers preventing the technology from being used to bridge the digital divide in both developed and developing markets. In fact, a representative business case shows that even in comparatively lower revenue developing markets which require expensive satellite backhaul, operators can achieve $50K profit per site per year – rising to $196K in developed markets. This is hugely important in addressing the digital divide and as part of initiatives for reaching the next billion users.• The backhaul whitepaper concludes that backhaul does not constitute a barrier to public access small cell deployments. It finds that the full-range of use cases ranging from high-traffic urban hotspots to rural blackspots can be efficiently managed using fibre, copper, and wireless backhaul techniques. Backhaul has been viewed as a major constraint to small cell deployments: this paper shows how those worries may have been over-stated and that feasible solutions are commercially available today.• Having already brought together the operator community to agree the key requirements for residential small cells, the Forum is now developing the key requirements for future public access vendor equipment. This includes enhancements to the Iuh small cell standard for public access, fully open X2 interoperability for LTE products and enhancements to provisioning that support multi-technology (3G, LTE & Wi-Fi) small cells. These requirements

fam’s teleco news (Año3-Nº12/Marzo 2013) 10/12will drive the Forum’s work to facilitate future public access deployments which will form a key focus of future Releases.Over the next 12 months, the Forum will publish Release Two which will contain significant updates on enterprise small cells and Release Three on metrocells. Crucially, these will include lessons from the deployments currently taking place as well as evolving approaches and standards. Subsequent Releases will contain major updates to rural and multi-technology small cells which intelligently integrate 3G, LTE and Wi-Fi, reflecting the work the Forum is undertaking with the Wireless Broadband Alliance.“The small cell industry is at a defining moment. Over 98% of operators think small cells are essential to their future and femtocells alone outnumber macrocells globally and are expected to constitute over 85% of all base stations by 2017. Yet existing deployments have centred on almost 50 pioneering and mostly very large operators in developed markets. How do we help the next 150, more conservative, operators of all sizes from across the globe roll out small cells of all types?” said Gordon Mansfield, Chairman of the Small Cell Forum. “Our new Release programme is expressly designed to overcome this challenge. Each Release provides everything an operator needs to know to profitably roll out small cells successfully and with minimal risk. Other organisations use formal Release programmes to powerful effect, including the Broadband Forum and 3GPP to drive uptake of technologies like DSL, fibre optic and 4G.”Each Release contains a concise summary of everything an operator needs to know to deploy small cells as well as detailed documents on key areas such as market drivers, business case, key technology information including standards, operator lessons, regulatory information and a profile of recommended equipment specifications that can be requested in RFPs. Release One is freely available from the Small Cell Forum Release site except the profile which is only available to Small Cell Forum members – www.scf.io/De: Small Cell Forum Press Releases

10.- Energy Impact of Emerging Mobile Internet Applications on LTE Networks: Issues and Solutions.Mobile Internet applications run on devices such as smartphones and tablets, and have dramatically changed the landscape of application generated network traffic. The potent combination of millions of such applications and the instant accessibility of high-speed Internet on mobile devices through 3G and now LTE technology has also changed how users themselves interact with the Internet. Specifically, the radio states in LTE such as RRC_Connected and RRC_Idle were designed with more traditional applications such as web browsing and FTP in mind. These traditional applications typically generated traffic only during Active (Connected) state, and once the user session ended, usually the traffic ended too, thus allowing the radio to move to Inactive (Idle) state. 

fam’s teleco news (Año3-Nº12/Marzo 2013) 11/12

However, newer applications such as Facebook and Twitter generate a constant stream of autonomous and/or user generated traffic at all times, thus erasing the previously clear demarcation between Active and Inactive states. This means a given mobile device (or user equipment, in LTE parlance) often ends up moving between Connected and Idle states frequently to send mostly short bursts of data, draining device battery and causing excessive signaling overhead in LTE networks. This problem has grown and attracted the research community’s attention to address the negative effects of frequent back and forth transitions between LTE radio states.

In this article, the traffic characteristics of these emerging mobile Internet applications is first explored and how they differ from more traditional applications. Investigation their impact on LTE device power and air interface signaling is also presented. A presentation of a survey of state-of-the-art solutions proposed in literature to address the problems, and analysis of their merits and demerits is done. Lastly, a discussion of the solutions adopted by 3GPP including the latest developments in Release 11 to handle these issues, and present potential future research directions in this field is also made. De: Telecom Insights; doc: Energy Impact of Emerging Mobile Internet Applications on LTE Networks: Issues and Solutions
