The company’s Xtreme Range (XR) cards operated on non-standard IEEE 802.11 bands, which reduced the impact of congestion in the 2.4 GHz and 5.8 GHz bands. In August 2007 a group of Italian amateur radio operators set a distance world record for point-to-point links in the 5.8 GHz spectrum. Using two XR5 cards and a pair of 35 dBi dish antennas, the Italian team was able to establish a 304 km (about 188 mi) link at data rates between 4 and 5 Mbit/s.
