An overview of Wireless Networks WLAN.
The purpose of this paper is to present the reader with a brief description of the requirements for a combined wired and wireless network, the importance of the capacity of a wireless network, and to solidify the authors knowledge in the area of telecommunication gained in the last four weeks. The paper includes an overview of wireless network and general terminology needed to understand the issues. The topic of the paper has been substituted from the original topic: Describe the LAN of your company. The paper is the result of a study of several white papers retrieved from the World Wide Web.
In recent years there has been increasing interest shown in wireless technologies for subscriber access, as an alternative to traditional twisted-pair local loop. A logical question is why this increase interest? Tom Fout in his paper titled Wireless LAN Technologies and Windows XP reports that the availability of wireless networking and wireless LANs can extend the freedom of a network user, solve various problems associated with hard-wired networks and even reduce network deployment costs in some cases.
Why a Wireless LAN? Fout elaborates that high-speed wireless LANs can provide the benefits of network connectivity without the restrictions of being tied to a location or tethered by wires. Wireless connections can extend or replace a wired infrastructure in situations where it is costly or prohibitive to lay cables. Temporary installations represent one example of when a wireless network might make sense or even be required. Some types of buildings or building codes may prohibit the use of wiring, making wireless networking an important alternative. Reliability, security and productivity "the same requirements that led users to adopt LANs more than 20 years ago "are compelling them to use wireless LAN (WLAN) technology today (Trapeze).
Another reason why WLAN is attractive is that today's standards-based wireless LANs operate at high speeds.
