Although 3G is a technical success, it is not yet clear that it will be an economic one. Deployment of a 3G service requires enormous up-front investments in spectrum and equipment, and wireless service providers are struggling to build business cases to support this investment. In contrast, small 'organic' networks based on IEEE 802.11 and Bluetooth standards are gaining rapid market acceptance, in part because of the initial investment required for these systems.
Future "organic" wireless networks will feature high data rates, short transmission links, adaptive interference mitigation methods, flexible spectrum usage, and rapid set-up and tear down of data links. These characteristics will require a variety of technology advances in the area of modulation, antenna diversity and beamstearing, software radio, and synchronization. In this talk we explore some of these new technologies and suggest directions for fruitfull future research.
