Note
If both interfaces of access points with two IWLAN interfaces are operated in the same

frequency range,

•

the distance between the antennas connected to R1A1, R1A2, R1A3 and those

connected to R2A1, R2A2, R2A3 must be at least 1 m.

•

there may be wireless interference on one or both IWLAN interfaces if the transmit power

is higher than 15 dB.

Note
Terminating resistor
Each WLAN interface has three antenna connectors. Connectors that are not used must

have a terminating resistor fitted, see Accessories.
The antennas R1A1 and R2A1 must be always be connected as soon as the associated

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.
You will find information on the configuration of the antennas in the following documents:

•

SCALANCE W7x8

SCALANCE W700 configuration manual, section "Configuring antennas"

•
