WiMAX is a wireless technology that provides broadband connections over long distances, aiming to provide a wireless alternative to cable and DSL. It uses the IEEE 802.16 standard and operates similarly to WiFi but over greater ranges of up to 30 miles and faster speeds of up to 70 megabits per second. A typical WiMAX system includes a base station and WiMAX-enabled devices. WiMAX is predicted to provide wireless broadband access to rural areas and see increasing adoption in India.
