Abstract :
Wireless local area network has become the most popular tools in maintaining internet communications especially at home, universities, hotels and workplaces. This is due to cost effective, fast deployment, provide high data security, reliability, easy to install and maintaining as compared to wired local area network. The Wireless local area network operates in two frequency bands. The IEEE802.11b/g operates at 2.4GHz ISM band, IEEE802.11a operates at 5GHz UNII band where as IEEE802.11n operates in dual-band of 2.4GHz and 5GHz. Both the ISM and UNII are unlicensed bands. Basically, doubling the operations frequency would reduce the coverage distance however manufactures claiming the IEEE802.11n could increase the coverage areas. According to Newton´s Inverse Square Law, where the received RF signal strength is proportional to the inverse square distance from the source. This paper investigates the coverage performance between IEEE802.11b/g and IEEE802.11n.
