isolation of the main antenna and the diversity antenna is required to be bigger than 12 dB.

8 Debugging Environment and Method

In the process of the actual implementation, it is necessary to adopt the switching board to

convert MINI PCIE module interface into the standard USB interface to connect the host for

debugging verification. It is also necessary to connect external power supply adaptor to provide

the module with sufficient current, and the diagram for the switching board is as follows:
