What’s Wi-Max?

Wi-Max is an IP based, wireless broadband access technology that provides performance similar to 802.11/Wi-Fi networks with the coverage and QOS (quality of service) of cellular networks. Wi-Max stands from "Worldwide Interoperability for Microwave Access.

Wi-Max is a wireless digital communications system, also known as IEEE 802.16 that is intended for wireless "metropolitan area networks". Wi-Max can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the Wi-Fi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m).

With Wi-MAX, Wi-Fi-like data rates are easily supported, but the issue of interference is lessened. Wi-MAX operates on both licensed and non-licensed frequencies, providing a regulated environment and viable economic model for wireless carriers.

At its heart, however, Wi-Max is a standards initiative. Its purpose is to ensure that the broadband wireless radios manufactured for customer use interoperate from vendor to vendor. The primary advantages of the Wi-Max standard are to enable the adoption of advanced radio features in a uniform fashion and reduce costs for all of the radios made by companies, who are part of the Wi-MAX Forum - a standards body formed to ensure interoperability via testing. The more recent Long Term Evolution (LTE) standard is a similar term describing a parallel technology to Wi-Max that is being developed by vendors and carriers as a counterpoint to Wi-MAX. http://www.Wi-Max.com/general/what-is-Wi-Max

History

In the mid 1990's, telecommunication companies developed the idea to use fixed broadband wireless networks for potential last mile solutions to provide an alternate means to deliver Internet connectivity to businesses and individuals. Their aim was to produce a network with the speed, capacity, and reliability of a hardwired network, while...
