Introduction

In addition to Ethernet over wired LANs, there is another technology that is omnipresent in LANs today. That other LAN technology is what we commonly call Wireless, or WiFi. Today in most homes and in many professional and academic environments, users are easily accommodated through the availability of Wireless networks. The popularity of Wireless networks is visibly evident today in that virtually all portable computing equipment (such as laptops and pads) is sold with Wireless capability built in. Wireless networks have tremendous convenience to offer, but at a cost.  Wireless networks are generally slower and less secure than wired networks. Wireless networks require more planning than do wired networks, and Wireless networks have to be carefully designed to operate at their fullest potential. However, in spite of the problems that wireless networks may present, the convenience of Wireless networks is such that they are frequently the one LAN technology that people most often use.
