Bluetooth and wireless LAN arbitration

摘要

Bluetooth and wireless LAN arbitration is described. In embodiments, a communication device includes a Bluetooth device for Bluetooth communication according to Bluetooth protocol, and includes a wireless LAN device for network communication according to wireless network protocol. An antenna switching circuit connects the Bluetooth device to an antenna for the Bluetooth communication, and connects the wireless LAN device to the antenna for the network communication. An arbitration control system arbitrates when the Bluetooth device is connected to the antenna via the antenna switching circuit and when the wireless LAN device is connected to the antenna via the antenna switching circuit.

主权项

1. A communication device, comprising:
a Bluetooth device configured for Bluetooth communication according to a Bluetooth protocol; a wireless local area network (WLAN) device configured for network communication according to a wireless network protocol; and an antenna switching circuit configured to connect the Bluetooth device to an antenna for the Bluetooth communication via one of three different communication paths and further configured to connect the WLAN device to the antenna for the network communication via the same or another of the three different communication paths, each of the three different communication paths:
being connectable to the antenna via a single-pole triple-throw (SP3T) switch coupled to the antenna; andhaving respective receive portions that are connectable to a reception coupler via another SP3T switch, the reception coupler operably coupled to respective receive ports of the WLAN device and the Bluetooth device.
