Universal Wireless Transport: from Rhetoric to Reality

Dr. Omar Bakr, Tarana Wireless
Abstract / Description: 

Tarana has made fundamental advances in radio performance that power industry's first truly viable wireless transport alternative to the high cost and complexity of fiber. With traditional wireless technologies, performance becomes very unpredictable in environments where links are obstructed by buildings and interfered with by neighboring links, which is typical in densely populated urban areas. As a result, networks today have struggled to scale their capacities in order to meet the growing demand in mobile data. In contrast, with Tarana's adaptive beam technology, networks maintain peak or near peak performance even in dense urban deployments. For network operators, this not only means significant reduction in costs associated with network planning and maintenance, but also much better utilization of spectrum assets. Tarana's solution features advanced interference cancellation technology that increases spectral efficiency by 10-50x compared to state-of-the-art cellular technologies, and improves reliability in unlicensed spectrum.

In this talk, we give an overview of Tarana's universal wireless transport technology and discuss different applications where it can be used to support mobile data explosion in the coming decade. We also review the methodology for validating different performance claims in both theory and practice.


Omar Bakr completed his PhD in computer science from UC Berkeley in 2010. During his doctoral studies at Berkeley, as member of both the Berkeley Wireless Research Center (BWRC) and the Technology Infrastructure for Emerging Regions (TIER) group, he worked on developing techniques to leverage information and communication technologies (ICT) to reduce the cost of delivering services to rural and under‑served areas. His thesis work focused on low cost techniques for building high gain antenna arrays for extending the reach and reducing the cost of wireless infrastructure. In 2009, he co-founded Tarana Wireless, where he currently serves as Chief Scientist, to develop technologies and solutions to support future growth of wireless networks. He has co-authored several papers and holds several pending patents in the fields of networking, communications, and signal processing.
