Abstract:The concept of White Spaces is best understood in the context of emerging software defined radio capabilities in transceiver designs as well as new network architectures for cellular (licensed usage) as well as WiFi (unlicensed usage) that potentially allow opportunistic use of new, unlicensed spectrum. In this talk, I will describe the principles of such cognitive usage, and what itmeans for emerging 4G and beyond (5G) network scenarios for operators and vendors. Specifically, the talk will highlight the role of white spaces in meeting key 4G/5G goals enhanced network throughput per user, and meeting new backhaul requirements for delivering broadband in both dense metro as well as rural (underserved) scenarios.
