Is wireless data dead?

Abstract

Summary form only given. In this presentation, we explore in greater detail the challenges faced by wireless data services, and some of the technology developments and possible solutions that lead us to be optimistic that wireless data is not yet dead, and in fact, has a very promising future. In particular, new spectrum allocations, coupled with integrated circuit technology breakthroughs, will enable much higher data rates. For example, the FCC has recently allocated spectrum for the Unlicensed NII Band at 5.15 GHz (350 MHz) and in the 60 GHz band (an incredible 5 GHz of available spectrum). Furthermore, ubiquitous digital cellular telephones will provide a widely available, flexible, and moderate rate digital channel for voice and data over the wide-area. And new networking technologies, in particular, wireless overlay networks and spectrum sharing techniques, will make it possible to maintain connectivity as a user moves from room-sized wireless networks, to building-sized networks, to the metropolitan, wide-area, and regional networks.
