Intel has produced its first WiMax chipset - the Connection 2250.

The system-on-a-chip supports the WiMax standard that serve stationary users, but it can also be upgraded for nomadic and mobile use. It will ship by year's end, the company said.

WiMax is a system for broadband-speed IP networks that reach across metropolitan or rural areas, and hit the market in 2004 for use with stationary subscriber devices designed to stay in a home or office. Now a mobile version, based on the IEEE 802.16e-2005 specification, is emerging with the promise of letting users take their broadband with them and even use it while traveling in a car or train.

The WiMax Connection 2250 is Intel's follow-up to its Pro/Wireless 5116, codenamed Rosedale, which was designed only for fixed WiMax and shipped in 2004. With the new processor, service providers can roll out fixed services and later upgrade their offerings through a quick over-the-air software upgrade, according to Intel. It is also designed to work with the company's multiband WiMax radio, which is designed to transmit and receive signals in the 2.5GHz, 3.5GHz and 5.8GHz bands.

WiMax is expected to be deployed mostly on licensed frequencies. Sprint Nextel is planning a US network that will use the 2.5GHz band, and in other parts of the world, WiMax is being deployed in the 3.5GHz band. The 5.8GHz band is unlicensed spectrum now used by some Wi-Fi equipment.

Motorola has announced it will use the 2250 chip in its CPEi 200 series of WiMax customer equipment, which the company plans to ship next year. Other system vendors committed to using the 2250 include Alvarion, Airspan, Alcatel, Aperto, Redline and Siemens.
