order to highlight that which technology will be better to build a wireless access infrastructure. The first part of the paper examines the both of these wireless technology in order to understand both technologies and their underlying concepts. Then, I have discussed some key characteristics to compare the both of these technologies. The last part concludes and presents a conclusion of which will be the best technology to build a wireless access infrastructure. II. OVERVIEW OF THE CANDIDATE TECHNOLOGIES. 2.1 Wi-Fi The dream to network PCs and other devices without the cost and complexity of cable infrastructures has driven the rapid growth in the wireless market over the last few years.Wi-Fi is one of the wireless technology which appeared early in the wireless market. Wi-Fi is based on the IEEE 802.11 wireless local area network (WLAN) specification. Actually it was designed to be used indoors at close range for example home user and office environment. The main goal of Wi-Fi technology is to provide service for mobile computing device like laptop. But recently it is used for more services for example consumer device such as televisions, digital cameras, and DVD players. A user with a mobile computing device such as a laptop, cell phone, or PDA which is Wi-Fi enabled can connect to the global Internet when it is within in range of an access point. The region which is covered by one or more access points is called a hotspot. Hotspots can range from a single room to thousand of square feet’s of overlapping hotspots. Wi-Fi can also be used to create a mesh network. Wi-Fi also allows connectivity in peer-to-peer (wireless ad-hoc network) mode, which enables devices to connect directly with each other [1]. This connectivity mode is useful in consumer electronics and gaming applications [1]. Wi-Fi products can use different radio frequencies [2]: • The 802.11a standard
