Fixed wireless access and radio LANs
Michael J. Willis · Institution of Engineering and Technology eBooks · 2012
This chapter is written within the framework of the provision of broadband data services to all locations using whatever technology is appropriate. We will concentrate on provision of high bandwidth data via radio systems to fixed terminals. Fixed terminals for this purpose may be defined as terminals where an antenna may be permanently installed on a mast, building or other structure. This type of service is distinguishable from fixed link service in several ways that are important from the propagation side. These networks are generally arranged in a point-to-multipoint or a mesh network topology. Radio paths are relatively short and terminals may not be optimally located for reliable propagation. The term fixed wireless access (FWA) will be used to describe these networks and applications. The main requirements placed on FWA systems when compared to mobile systems will be a relatively high data capacity, low latency, adequate coverage and high temporal reliability.
