Electrical

2.1

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.
