50 Ω-terminating resistor
Each WLAN interface has three antenna connectors. Connectors that are not used must
have a 50 Ω terminating resistor fitted.
The antennas R1A1 and R2A1 must be always be connected as soo

WLAN interface is turned on. If no antenna is connected, the relevant interface must also be
disabled for Rx and Tx. Otherwise, there may be transmission disruptions.
