Operating Frequency

2.4GHz is used by both the 802.11b and 802.11g standards. This signaling frequency enables high data rates at bigger ranges. 2.4GHz WLANs can experience interference from cordless phones, microwaves, and other WLANs. 5GHz is used by the 802.11a standard. 5GHz signaling frequency has a much greater spectrum and is relatively free from interference.
