Tigard, Ore.-based WiFi Wireless recently announced it has developed mobile wireless data network based on the 802.22 standard that provides download data rates ranging from 200 kb/s to 1.53 MB/s. The network uses narrowband channels and features a proprietary segmented antenna technology that allows clustering of up to 25,000 users per base station, the company said. Because the network is able to use UHF spectrum, it also provides range of up to 10 miles, with limited line-of-site restrictions, which reduces the number of base stations needed per coverage area. In contrast, the typical 802.11 hotspot offers a range of up to 150 feet, the company said.
