Wirelesslan Deployments: An Overview
Craig J. Mathias · Kluwer Academic Publishers eBooks · 2005
Wireless LANs allow LAN services to be delivered without the need for a wired connection between the client and the supporting infrastructure. Most products today use some form of spread-spectrum microwave transmission, typically operating in unlicensed bandwidth. In addition, most products are based on a microcellular infrastructure, allowing roaming through arbitrarily-large areas. With the emergence of the extensible IEEE 802.11 standard, the number of available products has increased dramatically, and products based on second-generation 802.11 PHYs are offering through put commensurate with wired LANs. Issues related to deployments are normally limited to the placement of access points according to the coverage desired and the constraints of specific in-building RF propagation, educating users with respect to antenna location and orientation, and interference management. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
