Worldwide Interoperability for Microwave Access. In the rapidly-evolving sphere of wireless technology, WiMAX is the next generation in wireless access to the Internet with speeds that are equivalent to cable or DSL connections. While Wi-Fi focused on providing wireless LAN and Internet access, WiMAX is geared to deliver broadband access over a range of 10 to 50 km at speeds varying from 10 to 70 Mbps. There are two main types of WiMAX: Fixed WiMAX and Mobile WiMAX. Similar to cellular networks, the WiMAX service is provided through a base station. In the case of Fixed WiMAX, you are limited to the range of the base station; in the case of Mobile WiMAX, you will be able to continuously access the Internet on the move, and you would get automatic handover when you cross from the range of one base station to another.
