Hardware Features
Dual-Radio Operation
The access point supports simultaneous radio operation using a 2.4-GHz 802.11g radio and a 5-GHz
802.11a radio. Each radio uses dual-diversity integrated antennas.
The 5-GHz radio incorporates an Unlicensed National Information Infrastructure (UNII) radio
transceiver operating in the UNII 5-GHz frequency bands. The 802.11g radio is called Radio0 and the
802.11a radio is called Radio1.
