Even though Wireless networks directly contribute only to a portion of the overall network infrastructure, attention to all network functions is necessary to counter impairments resulting from the Wireless medium.
Wireless Network System Components A wireless network consists of several components that support communications using radio or light waves propagating through an air medium. Some of these ele-ments overlap with those of wired networks, but special consideration is neces-sary for all of these components when deploying a wireless network. Figure 2-1
