Testing LTE-U 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.… Read more »

Panel Discussion: LTE for public safety – are we ready?

Andy Berg — Wireless Week (co-Moderator) Emil Olbrich — Signals Research Group Jim Harper — Elektrobit Wim Brouwer — Alcatel-Lucent 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… Read more »

Channel sounding for 5G/mm-wave

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… Read more »

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… Read more »

Key trends and drivers shaping LTE/LTE-A and beyond

Olga Shapiro — Frost & Sullivan As the IoT is quickly moving into various industries and applications, the telecommunications industry, among others, will see a greater number of smarter, faster, and wearable devices for consumers. This, in turn, will continue driving the demand for test equipment solutions. The idea that 5G will be necessary to… Read more »

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… Read more »

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… Read more »

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… Read more »

LTE network optimization for public safety

Michael Schwab — P3 Communications, Inc Public Safety and Critical Communications Entities have been focusing on speech services and low data rate applications for decades. Nowadays information flow is frequently limited by interoperability problems like different standards or independent systems. Long-Term Evolution (LTE) has a chance to revolutionize the public safety sector and its processes.… Read more »
