3.7.2 SOM RF Interfaces for Wi-Fi and Bluetooth Antennas

The Wi-Fi/BT module on the SOM includes the following RF antenna interfaces:

•

ANT0: Wi-Fi antenna 1

•

ANT1: Wi-Fi antenna 2

•

ANT2: Bluetooth antenna

Wi-Fi antennas

: The ANT0 port is for one of the two Wi-Fi antennas and ANT1 is for the other Wi-Fi antenna.

Since the Wi-Fi module uses 2x2 MIMO technology and operates in both the 2.4GHz and 5GHz bands, two

dual-band antennas are required to be connected to achieve the full performance of the Wi-Fi interface. By

default, both antenna ports are connected to the carrier board PCB antennas labelled “WLAN ANT1” and

“WLAN ANT2” via coaxial cables. Other suitable antennas may be used by connecting them directly to the Wi-

Fi antenna ports on the module with MHF4 coaxial connectors.

Bluetooth antenna

: The ANT2 port is for a dedicated Bluetooth antenna. By default, this port is connected to

the carrier board PCB antenna labelled “BT” via a coaxial cable.

The Wi-Fi/BT module is designed with a dedicated Bluetooth antenna port so that the Bluetooth and Wi-Fi

antennas can be physically separated in the end product to provide better isolation between them. This is done

to improve concurrent Wi-Fi and Bluetooth operation. The greater the separation between antennas, the better

the concurrent Wi-Fi – Bluetooth performance will be.
