Intel has officially launched its broadband wireless WiMax chipset, formerly known as Rosedale.

WiMax, also known by its IEEE standard number 802.16, enables high-speed data throughput over large distances, potentially as much as 15 miles.

Intel is trialling services in some countries and expects the first deployments to be in areas where wired broadband is currently unavailable.

"WiMax can provide the platform for the next generation of internet expansion, connecting the next billion internet users," said Scott Richardson, general manager of Intel's broadband wireless division.

"In addition to delivering the first flexible, highly integrated WiMax system-on-a-chip, Intel has worked with a number of parties, including carriers and equipment manufacturers, to prepare the industry for the next wave of wireless technology."

Sean Maloney, head of Intel's mobility group, confirmed last week that the company was already manufacturing WiMax products, and that he expected BT to be offering WiMax connections within the next 18 months.

Analysts predict a bright future for WiMax and see it replacing or augmenting existing cable and DSL services.

But there are potential problems for early adopters of the technology. A revision to the 802.16e WiMax standard is due out next year and, while Intel has committed to making the new and old standards interoperable, older equipment is unlikely to be upgradable.

Richardson will be giving more details of the technology and plans for rollout at a WiMax access conference at Olympia tomorrow.
