Abstract

Worldwide interoperability for microwave access (WiMAX) is a wireless standard that introduces orthogonal frequency division multiple access (OFDMA) and other key features to enable mobile broadband services at a vehicular speed of up to 350 km/h. WiMAX complements wireless local area networks (WLANs) and competes with other third generation (3G) and forth generation(4G) wireless standards such as 3GPP-LTE Advanced on coverage and data rate. More specifically, WiMAX supports a much larger coverage area than WLAN, does not require line of sight for a connection, and is significantly less costly compared to the current 3G and 4G cellular standards. Although the WiMAX standard supports both fixed and mobile broadband data services, the latter (mobile WiMAX-IEEE 802.16m) have a much larger market. Therefore, this article will briefly compare both the Fixed and Mobile WiMAX standard, the technologies deployed for the air interface and the network, and its potential for successful deployment in the next generation of broadband wireless networks.
