Antenna ports

ConnectCore 6 module variants supporting both Bluetooth and WLAN are populated with one single antenna port covering both 2.4 and 5 GHz frequencies.

Module variants supporting only WLAN provide additionally antenna diversity feature. Two antenna ports supporting the same transmit and receive signals are populated on the product. The software running on the ConnectCore 6 SOM switches from one antenna port to the other depending on the RSSI (Receive Signal Strength Indication) of the received beacon, which guarantees that the antenna with the best signal is always used and thus improve the quality and reliability of the wireless link. The interval between comparisons of RSSI values on the two antennas is by default 10 seconds, but can be configured in software. Furthermore, when the RSSI measured is too low, the software will automatically switch to the other antenna regardless of the 10 second interval. Hence, antenna diversity is an option and it is absolutely safe to mount only one antenna in the system, connected for instance to the primary antenna port.

The following image shows the location of the primary antenna.

Note Modules with Bluetooth capabilities will not support spatial diversity.
