Anand, de Veciana, Shakkottai Awarded William R. Bennett Prize

WNCG alumnus Arjun Anand and WNCG professors Gustavo de Veciana and Sanjay Shakkottai have been awarded the 2021 William R. Bennett Prize from the IEEE Communications Society.

The prize is awarded annually to the authors of a single paper published in either in IEEE/ACM Transactions on Networking or the IEEE Transactions on Network and Service Management. The paper must have been published within the last three years prior to the award.

Prof. Jeff Andrews Discusses 5G on Science Vs

WNCG professor Jeff Andrews appeared as a guest expert on a recent episode of Gimlet Media's Science Vs podcast, "5G: Welcome to the Revolution?" where he provided background on the next generation of wireless technology.

The episode noted the general public's increased interest in 5G and explored the basics of the technology, addressing the controversies and myths building around the topic.

Machine Learning to Improve Success Rates for Handovers from Sub-6 GHz LTE to Millimeter Wave Bands

Transmission over millimeter wave (mmWave) frequency bands is being adopted in fifth generation (5G) wireless communications.  Even though the sub-6 GHz frequency bands continue to dominate deployments due to their better ability to penetrate and provide in-building coverage, the handover between mmWave and sub-6 GHz frequency bands is nonetheless inevitable to support higher data rates.  The cost of a handover is a reduction in data rate, which 5G promises to increase.

AT&T and Ericsson World Debut 5G Tech at UT

Millimeter wave is an essential and fundamental component for 5G mobile networks and AT&T’s plans. The 5G demo at TWS showcased the possibility and feasibility of millimeter wave radio access technology for the cellular networks of the future. Developed by Ericsson, the new systems incorporated key 5G technologies, including large system bandwidth, phased arrays with ultra-fast beam steering, feedback-based hybrid precoding, multi-user Multiple Input Multiple Output (MIMO), dynamic beam tracking and beam acquisition.

FCC Announcement Makes New Spectrum Available for Millimeter Wave

The FCC recently announced new spectrum for millimeter wave. The new rules open nearly 11 gigahertz of high-frequency spectrum for mobile and fixed wireless broadband, which include 3.85 GHz of currently licensed spectrum and 7 GHz of unlicensed spectrum. This decision could prove critical for the U.S. to retain its leadership in the field of wireless communications.

WNCG Receives Huawei Award for Best Collaboration

WNCG Profs. Gustavo de Veciana and Jeff Andrews recently received an award for Best Collaboration with the wireless group at Huawei. This international award goes to a funded university collaboration the company deems most impactful from among their offices and partner institutions worldwide.  

“We are very pleased to accept this award,” Prof. de Veciana states. “The experience of working with engineers at Huawei has been very rewarding and fun.”  

Analyzing Uplink Massive MIMO Using Stochastic Geometry

Massive multiple-input multiple-out (MIMO) is a promising technique for 5G cellular networks. Prior work showed that high throughput can be achieved with a large number of base station antennas through simple signal processing in massive MIMO networks. The performance of massive MIMO in a large-scale network with irregular base station locations and random user distributions is not yet fully understood.

Initial Beam Association in Millimeter Wave Cellular Systems: Analysis and Design Insights

Wireless communication via millimeter wave (mmWave) frequencies is a key component of future cellular systems. mmWave deployments will use beamforming with large antenna arrays by both the base stations and mobile stations to ensure sufficient received signal power. Prior work on coverage and rate of mmWave cellular networks focused mainly on the case when base stations and mobile users beamfomring vectors are perfectly designed for maximum beamforming gains.
