and 11 are the only group of three non-overlapping channels in the U.S. Equivalent isotropically radiated power (EIRP) in the EU is limited to 20 dBm (100 mW). The current 'fastest' norm, 802.11n, uses double the radio spectrum/bandwidth (40MHz) compared to 802.11a or 802.11g (20MHz). This means there can be only one
