Introduction

Up to this point in the book, we ve explained the technologies behind wireless networking, as well as some of the essential components used to support a wireless network. Now it s time to begin applying what you have learned thus far to network design. This chapter outlines the framework necessary to design a wireless network. We will also discuss the process associated with bringing a network design to fruition.

Initially, we will evaluate the design process with a high-level overview, which will discuss the preliminary investigation and design, followed by implementation considerations and documentation. The goal is to provide the big picture first, and then delve into the details of each step in the process. There are numerous steps diligently planning the design according to these steps will result in fewer complications during the implementation process. This planning is invaluable because often, a network infrastructure already exists, and changing or enhancing the existing network usually impacts the functionality during the migration period. As you may know, there is nothing worse than the stress of bringing a network to a halt to integrate new services and especially in the case of introducing wireless capabilities, you may encounter unforeseen complications due to a lack of information, incomplete planning, or faulty hardware or software. The intention of this chapter is to provide you with design considerations to help avoid potential network disasters.

The final portion of this chapter will discuss some design considerations and applications specific to a wireless network. These include signal budgeting,...
