Delegates to the International Telecommunications Union’s (ITU) World Radio Conference (WRC) in Geneva, Switzerland agreed to allocate 455 MHz of unlicensed spectrum in the 5-GHz band for global WLAN use. Once the agreement achieves final plenary approval, 100 MHz of spectrum (5.150-5.250 GHz) will be allocated for indoor WLAN use, while an additional 355 MHz will be allocated for mixed indoor/outdoor use (5.250-5.350 GHz and 5.470-5.725 GHz). The international agreement at the WRC effectively opens at least 19 non-interfering 5GHz channels for global WLAN use.
Atheros Communications described the agreement as “a defining moment for the WLAN industry as a whole.” Atheros noted that the universal 802.11a, 802.11b and 802.11g networks that it supports with its chipsets will offer access to nine times as many non-overlapping channels as 802.11b and 802.11g-only networks in the U.S., and seven times as many non-overlapping channels in Europe.
