Note
The three antenna for devices bintec WI1065n have 2 Transmit and 3 Receive func-
tions in n operating mode MIMO 2T3R. WLAN 1 Ant. 1 and WLAN 1 Ant. send and re-
ceive, Ant. 3 only receives.
For devices bintec WI2065n only 2 antenna are used for each of the 2 wireless mod-
ules. These are both sending and receiving antenna. There is no third receiving an-
tenna; this is MIMO 2T2R operating mode.
However gross rates of 300 Mbps are possible. The receiving sensitivity decreases
slightly. Only 2 antenna connections are required to operate bridgelink with dual polar-
isation antenna.
Antenna should be Lambda/2 or a multiple of this. In bintec WIx065n the antenna are
55 mm apart.
2.4 GHz Lambda/2 corresponds to 6.15 cm; 5 GHz Lambda/2 corresponds to 2.72 cm.
Devices with 802.11n support can use up to 3 antenna per wireless module. The assign-
ment of the existing 4 antenna connectors is shown in the following graphic:
