WiMAX (Worldwide Interoperability for Microwave Access) is a standard for wireless communications which covers a variety of transmission modes. Having a theoretical maximum of 70mbps symetic bandwidth, deployments can be of a point-to-point link or more cellular in nature. Based on the IEEE 802.16 standard, WiMAX is described as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL" http://www.wimaxforum.org/technology/
The SOWN WiMAX project was first proposed in June 2008 and confirmed in October 2008. This is a joint venture between SOWN and bluenowhere with WiMAX base stations being provided by NEC.
