3.7.4 Processor Board RF Specification for WIFI, BT

The Processor board includes the following radio interfaces:

o

Wi-Fi + BT: WiFi CH0

o

Wi-Fi only: WiFi CH1

o

WTR5975: For GNSS RF Front end

Antenna 0

:

Antenna 0 is the primary interface for WCN3990 to provide Wi-Fi

connectivity and Bluetooth connectivity. This antenna connector is connected to carrier
board PCB antenna via a coaxial cable. ANT0 is a standard dual band antenna from
2.4 GHz to 5 GHz and BT.

Antenna 1

: Antenna 1 is for WCN3990 to provide Wi-Fi. Antenna connector ANT1 is

connected  to  the  carrier  board  antenna  via  a  coaxial  cable.  The  function  of  this
connector  is  for  extending  the  dual  band  capabilities  of  the  Wi-Fi  chip;  therefore,
enabling this antenna to be used simultaneously with Antenna 0. For example, Antenna
0 can be connected to 2.4GHz while  Antenna 1 can be connected to 5 GHz.

For details on connecting the WiFi module to the on-board PCB antennas on the carrier
board, refer to section 0 below.

For GNSS details, See section

3.8.23 GNSS Card
