Mobile WiMAX as a Next Generation Broadband Wireless Networks
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 Fourth 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.
