Both chapters concentrated on mobile computer communications. This chapter focuses on communications that are fixed and at higher data rates. There are as many variations in high-speed wireless systems as there are variations in wireline systems. Fixed-wireless systems have a long history. Frequencies used range from 1 GHz to 40 GHz.
Some vendors also use the terms to refer to privately deployed networks.
The goal of this chapter is to show how fixed-wireless systems are no longer a communications tool restricted to large or specialized organizations. They are available to almost any size company in a variety of ways for a variety of purposes. You ll find that you have a wide range of choices, including whether to use licensed or unlicensed spectrum, whether to deploy a private network or use a carrier network, and whether to use a terrestrial network or a satellite network. In some cases, you may not even know that your service provider is using wireless technology. This chapter discusses the options available, how the various technologies work and how to go about implementing a fixed-wireless solution.
