Michael Schwabs|P3 Communications, Inc.

Today, usually two separate wireless communications systems are in place to serve the needs of commercial applications on the one hand and critical communications, often referred to as public safety, on the other hand. This is due to the very different requirements for both systems. The vast success of LTE/LTE-Advanced becoming the wireless communications standard for delivery of mobile broadband data and high-definition (HD) voice has led to a commitment of governmental authorities to select LTE as the underlying technology for their next-generation public safety networks. At this panel we will explore if the technology is ready, if not what is missing. How the eco-system for "LTE for public safety is shaping up. These and other question will be answered during the discussion.

Understanding and testing LTE vulnerabilities

Vuk Marojevic|Virginia Tech

Continuous R&D support and innovation make LTE and its evolution appealing for a wide range of applications and services. In addition to high-capacity and high-mobility, future mobile broadband systems will also need to have high-availability to support mission-critical applications and flexibility to support new spectrum management paradigms. Researchers at Wireless@Virginia Tech have been investigating the vulnerabilities of LTE by analyzing its behavior in different signaling environments that can be expected in future deployments, such as AWS-3 and the new 3.5 GHz band. This presentation will present our methodology, testbeds, tools, and trials for analyzing the performance of LTE to targeted RF interference.

Understanding E911 Device Compliance in a VoLTE/IMS Environment

Balaji Ayyaswamy|Rohde & Schwarz

Delivering E911 services is an FCC requirement and has been a part of legacy services for some time. In order to support emergency services for VoLTE subscribers, many new items need to be considered from a device and network perspective. For example, the transition from a traditional circuit switched (CS) network to an all IP based network utilizing IMS for voice calls; and the addition of new positioning methods such as eCID, OTDOA, and A-GNSS with a new information exchange protocol (LTE Positioning Protocol); all add new dimensions to this mandatory feature that vendors must now ensure via functional and performance compliance of their devices.

Amit Khanna |Rohde & Schwarz

LTE-U, or LTE in the unlicensed 5GHz band, is a hot new technology being proposed to address the current capacity crunch for mobile operators. Through carrier aggregation, LTE in the unlicensed spectrum is combined with LTE in the licensed band to provide additional bandwidth and a fatter data pipe. By combining licensed bandwidth with unlicensed 5GHz spectrum, LTE-U will improve overall performance for operators and provide a framework for all spectrum types.

Real-world challenges in a LTE connected world

Real-world challenges in a LTE connected world

Keith Radousky|Quintel Solutions

Wireless subscribers are, and will continue to be ravenous for more bits. Forecasts of exponential data traffic growth have come true. Also VoLTE is now launching which exacerbates the capacity problem and just as important is the need for QoE. Carriers are scrambling to add capacity by deploying additional infrastructure including new Macrocells, LTE carriers, LTE 4Tx-4Rx, Cloud RAN, DAS and Small Cells. DAS and Small Cells are getting much attention but they are only feasible in a very small footprint of the network. More attention is needed on how to increase capacity on existing Macrocells and deploy Cloud-RAN. Accordingly, this session will focus on deploying LTE Advanced (4Tx-4Rx and 8Tx-8Rx) and more bands (600MHz, AWS-3) on Macrocells and realize Cloud-RAN. The growing problem of LTE uplink interference will also be discussed along with mitigation options.

The role of DAS in LTE-Advanced Deployment

Phil Wala|TE Connectivity

LTE-Advanced (LTE-A) comprises a family of enhancements to the LTE standard that promise to increase data rates and maximize spectrum efficiency through the implementation of new network technologies. Many of these new technologies present significant deployment challenges for the carrier, including greatly increased backhaul capacity and new requirements for inter-cell timing control and synchronization.

Distributed Antenna System (DAS) technology offers the tools needed to enable these new features, in a way that significantly mitigates the challenges and costs associated with deploying an LTE-A network. In this article, the author will discuss the role of DAS in addressing LTE-A deployment challenges. Specific topics to be discussed include use of multi-band DAS to increase data rates by enabling inter-band non-contiguous Carrier Agg

RF Sampling Architecture Drives LTE, 4.5G and Beyond

RF Sampling Architecture Drives LTE, 4.5G and Beyond

Russell Hoppenstein|Texas Instruments

The migration to next generation LTE systems will push for systems to handle larger bandwidths, higher frequencies, and increased density. The introduction of high sampling speed data converters facilitates directly sampling high bandwidth RF signals without having to implement a traditional mixing stage. The RF sampling converter incorporates new features in the digital realm to enable agile tuning, multi-band support, and manageable data rates to/from FPGA or processor. Proper frequency planning is introduced by adjustment of the sample clock to open up clean spectrum for maximum dynamic range and minimum spurious emissions which is needed for the standard. Digital data is transferred via serial link per the universally adopted JESD204B standard. The simplified architecture coupled with reduction in digital data lines allows for higher density systems that are needed for beam-forming and massive MIMO anticipated in next generation systems.

Wilhelm Keusgen|Fraunhofer Heinrich Hertz Institute

The millimeter-wave frequency band is seen as a good candidate for future 5G mobile radio networks. The availability of multiple Gigahertz of bandwidth promises to be an answer to the ever increasing data rates in access and backhaul links. Successful design of millimeter-wave mobile communication systems will rely on pro-found knowledge and modeling of the outdoor radio channel. Comparing to the legacy frequency bands, the knowledge at millimeter-wave frequencies is still very limited. The talk gives an overview over current extensive measurement campaigns of the 10 and 60 GHz mobile outdoor channel in urban and rural environments. Recent results .with respect to time-variance and the evaluation of basic channel parameters are presented. Finally a novel hybrid modeling approach useful for link and system level simulation is discussed

Ensuring VoLTE QoS in a Stressed Environment

Paolo Marini|Prisma Telecom Testing

Ensuring VoLTE QoS meets customers expectations Is VoLTE competing with or just complementing OTT-mediated VoIP Services (OTT Voice, such as Skype)? Service Providers propose VoLTE as an enhanced, efficient, reliable primary voice service – but Customers expect QUALITY ! End-to-end QoS validation is essential before VoLTE deployment! Unlike 2.5/3G networks, a 4G network is able, thanks to QoS and DiffServ, to identify, track and deliver traffic flows with specific QoS characteristics for latency, jitter, packet loss and error rates. LTE RAN functionality heavily impacts end-to-end QoS, thus RAN validation is central to delivering optimal voice services. Correct implementation of VoLTE ensures a much better quality than 3G or OTT Voice, with improvements such as lower delays, lower setup times, lower resource usage. Correct VoLTE implementation improves network efficiency maintaining legacy voice services quality.

Realizing Massive MIMO in LTE-Advanced and 5G

Charlie Zhang|Samsung

Elevation beamforming and Full Dimension MIMO (FD-MIMO) has been an active area of research and standardization in 3GPP LTE-A, as initial investigation showed that promising (3-5x) cell capacity and cell edge gain can be achieved with these new techniques. In an FD-MIMO system, a 2-dimensional (2D) active array is deployed to support Multi-user 3D elevation and azimuth beamforming, which results in much higher cell capacity compared to conventional systems. In this talk, we will provide a brief summary of 3GPP activities in the Massive MIMO area, including the recently completely 3D channel model, ongoing study on FD-MIMO scenarios, antenna/RF transceiver architectures, as well as potential network performance benefits.
