« Alvarion Releases Mobile WiMax System | Main | Sprint Reveals More 4G Details »
The first mention I’ve seen of WiMax-like devices in the 5.4 GHz stretch: This part of the 5 GHz band is one of two segments subject to rules that require unlicensed devices to back off on power and switch frequencies if radar use is detected. However, it’s a big hunk with 11 802.11a/n regular-width channels available. In WiMax, I’m not sure how 255 MHz of bandwidth translates into channels. There’s no approved profile for 5 GHz use of WiMax, but that doesn’t prevent using WiMax technology, certified in other bands, from deploying over 5 GHz.
The 5.4 GHz band doesn’t allow as much power output as the 5.8 GHz band, but the tradeoff is spectrum and utilization. There’s a lot less chance for interference in point-to-multipoint installations. Redline started taking orders last month for the unit, and said they have sold hundreds prior to their FCC certification.
