Abstract

A combo wireless system comprises a Bluetooth module, a wireless fidelity (WiFi) module, a single pole triple throw (SP3T) switch and an antenna. The antenna is utilized to transmit/receive Bluetooth signals for the Bluetooth module and to transmit/receive WiFi signals for the WiFi module. The SP3T switch is coupled between the antenna, the Bluetooth module and the WiFi module. The SP3T switch is controlled to select a path for the Bluetooth module to transmit/receive Bluetooth signals through the antenna, to select another path for the WiFi module to transmit WiFi signals through the antenna or to select another path for the WiFi module to receive the WiFi signals through the antenna.
