3.2.19 Antenna Interface
The SOM provides the fully-integrated WLAN and Bluetooth function.
The WLAN and Bluetooth share the antenna port with 50ohm impedance.
 WLAN supports 2 × 2 multiple input, multiple output (MIMO) with two spatial streams IEEE802.11
a/b/g/n/ac WLAN standards.
 Supports Bluetooth 5.0 + HS enabling seamless integration of WLAN/Bluetooth and low energy
technology.
 Optional dedicated BT antenna support -concurrent operation for WLAN and BT with and without
dedicated BT antenna
