IP optimized broadband wireless access
Abstract
Broadband wireless access (BWA) is moving into IP era. New open
interoperability standards, HiperAccess and IEEE802.16, optimized for IP
traffic are being developed enabling low cost, mass market systems. In
this paper BWA standardization, system design and regulation are
discussed

This article reviews the technologies and potential markets,
applications, and architectures for broadband wireless access. The
emergence of wireless communications for cellular systems is presented,
together with its projected future evolution to mobile wideband systems.
The field of broadband access systems, services, and network
architectures is also covered, and then systems for broadband wireless
communications for indoor local area networks and outdoor public fixed
access networks are discussed. Broadband wireless access systems are
emerging as a new and growing area of telecommunications, since the
ability to provide access without extensive installation of copper or
fiber infrastructures make wireless technology well suited for broadband
services. Finally, some of the key enabling technologies, such as
adaptive antennas and video compression, and the future architectural
directions of broadband wireless networks are presented
