tremendous benefits of wireless networks and the perceived drawbacks to them. Some of the key technical challenges in wireless communications come from (i) the hostile wireless propagation medium and (ii) user mobility. Most of the issues covered in this chapter arise in any data network, wired and wireless likewise.
