Figure 6: WiMAX vs WIFI CoverageFigure 6 shows WiMAX and WiFi coverage. Once one can clearly see how extensive the WiMAX coverage is. Wi-Fi and WiMAX match. WiMAX networks typically provide a WiMAX subscriber unit that is connected to the metropolitan WiMAX network and provides Wi-Fi located in homes or businesses for local devices, e.g. laptops, Wi-Fi handsets and iPhones for connections (Xiao, 2008). This encourages users to place the WiMAX subscriber unit in areas where it can be best received while still being able to use the WiMAX network for any location in the locality. WiMAX is more like Wi-Fi than 3G cellular technologies. Wi-Fi provides local network access over a few meters with a speed of around 54 Mbps, while a single WiMAX antenna has a range of up to over 40 miles with a speed of around 70 Mbps or more . WiMAX provides an Internet connection that can serve the local Wi-Fi network. These are mobile stations which assume the role of network source for the user; the second is the access service network which assumes two additional base stations and constitutes ASN gateways which create the radio access. The final part of the connectivity network which provides the IP functions and the base stations which provide the aerial platform for the mobile stations. The base stations also have management functions, tunnel establishment and triggering, radio resource control, active host control protocol proxy, service application excellence and management. of multicast clusters. The inclusion of ASN facilitates encryption keys, resource regulation, routing to the chosen network and consumer features. The Connectivity Services Network is responsible for Internet connections...... middle of paper ....... A. (2012). LTE, LTE-advanced and WiMAX: towards advanced IMT networks.
