Abstract

This utility model discloses an in-vehicle wireless communication module in the field of communication technology. The baseband processing chip in the in-vehicle wireless communication module is bidirectionally electrically connected to the radio frequency transceiver. The radio frequency transceiver is electrically connected to both a radio frequency transmitting component and a radio frequency receiving component. The radio frequency transmitting component includes a first radio frequency transmitting unit, a second radio frequency transmitting unit, and a third radio frequency transmitting unit, each corresponding to a different frequency band operating range. A main antenna and a diversity antenna are connected to the radio frequency transmitting component and the radio frequency receiving component of multiple frequency bands in different combinations via two independent radio frequency channels. The main antenna and the diversity antenna transmit and receive radio frequency signals of different frequency bands via the radio frequency channels. Using this in-vehicle wireless communication module can reduce the overall hardware cost of the in-vehicle wireless communication module and is compatible with multiple communication standards.
