Antenna ports
The radio will have two U.FL antenna connectors. The radio can transmit on one or two antennas depending on the
operating modes. Furthermore, the radio can receive on one or two antennas as well.
2.2
Temperature range
This radio will be characterized and will maintain RF electrical specifications as stated here when the radio is used
in the MCN, NCAP or HP-NCAP. Please refer to the mechanical functional specification of the respective AP.

Channel allocation and frequency operating range
2.5.1
2.4 GHz band
The 2.4 GHz operating frequency ranges from 2.312 GHz to 2.472 GHz. In addition to that, 2.484 GHz can also be
selected. Normally, channel center frequencies are tunable in 5 MHz steps and are define as follows:
Channel center frequency
