WiMax is a wireless technology that provides broadband internet access over long distances. It has several benefits over traditional internet connections like faster speeds, wireless connectivity without cables, and broad coverage across cities. WiMax can be used to provide portable mobile broadband, wireless internet alternatives to cable/DSL, data services, and business continuity. While it offers high speeds, coverage, and lower costs than other options, WiMax also has disadvantages like signal interference from weather and potential lower speeds with many users.
