Worldwide Interoperability for Microwave Access (WiMAX) is a communications technology that uses radio spectrum to transmit tens of megabits per second in bandwidth between digital devices such as laptop computers. Similar to WiFi, WiMAX brings with it the ability to transmit over far greater distances and to handle much more data.
WiMAX was developed by equipment manufacturers, service providers, and software companies around the world all of who were motivated to ensure that equipment, regardless of who made it, would will interoperate. In practice, WiMax will likely be made available to consumers by companies such as Cingular and Verizon. These companies have purchased the necessary rights to the radio spectrum and are building nationwide networks.
WiMAX will coexist as a radio capability on the mobile computer, along with other radio technologies such as wireless fidelity and third-generation (3G), for many years.
