LAN has been changed very drastically in today’s technological world. In present scenario Wireless (WLAN) offers tangible & excellent benefits over traditional wired networking. WI-FI (Wireless Fidelity) is a generic term that refers to the IEEE 802.11x standard which uses radio waves to provide wireless high speed internet. The WI-FI modes are Ad hoc, Infrastructure and Extended modes. Ad hoc does not use any access points because it is point to point communication. The other two modes uses access point as interface between wireless clients. Single access point can support up to 30 users that is range of 100-150 feet indoors and 300 feet outdoors. The coverage area depends on location were Access Point is being placed. The Access point has traditional Omni directional antenna. The main aim of this project is to increase the coverage area of Access point by replacing Omni directional antenna by Bi-Quad antenna with parabolic reflector. Bi-quad antenna operating frequency is 2.4GHz. It’s designed since 2.4GHz comes under the unlicensed wireless band usually used in WLAN.
