A radio frequency front-end includes a first path, second path, and third path each coupled between an antenna and a transceiver. The first path is configured to convey WLAN signals from the transceiver to the antenna for transmission. The second path is configured to convey received Bluetooth signals and received WLAN signals from the antenna to the transceiver. The third path is configured to convey Bluetooth signals from the transceiver to the antenna for transmission when a WLAN link is active and not in a power save state, and is configured to convey received Bluetooth signals from the antenna to the transceiver, and Bluetooth signals from the transceiver to the antenna for transmission, when the WLAN link is either inactive or in the power save state.

Bluetooth and WLAN coexistence architecture having a shared low noise amplifier

A system including i) first wireless communication circuitry to receive and transmit packets of a first type via an antenna, and ii) second wireless communication circuitry to receive and transmit packets of a second type via the antenna. The packets of the second type are transmitted and received during time slots having a predefined length, and the time slots are separated by time intervals during which no packets of the second type are transmitted or received by the second wireless communication circuitry. The system further includes an arbiter to control access of the first wireless communication circuitry and the second wireless communication circuitry to the antenna, wherein the arbiter causes the packets of the first type to be transmitted and received by the first wireless communication circuitry during the time intervals during which no packets of the second type are transmitted or received by the second wireless communication circuitry.

Systems and methods for controlling the transmission and reception of packets over a common antenna

A radio frequency (RF) front-end configured to share transmissions and receptions of Bluetooth signals and WLAN signals. In an exemplary embodiment, the RF front-end comprises a first path coupled between an antenna and a transceiver dedicated to transmissions of the WLAN signals; a second path coupled between the antenna and the transceiver dedicated to simultaneous receptions of the Bluetooth signals and the WLAN signals; and a third path coupled between the antenna and the transceiver. The third path may be dedicated to transmissions only of the Bluetooth signals when a WLAN link is active; and transmissions and receptions of the Bluetooth signals when the WLAN link is active and in a power save state, and when the WLAN link is inactive.

Systems and methods for controlling the transmission and reception of WLAN and short range wireless packets over a common antenna. The system includes WLAN communication circuitry to generate data packets for wireless transmission via the antenna and to process data packets received via the antenna, and includes short range wireless communication circuitry to receive and transmit audio packets via the antenna. The system further includes an arbiter to control access of the WLAN communication circuitry and short range wireless communication circuitry to the antenna. The arbiter causes the data packets to be transmitted and received by the WLAN communication circuitry during time intervals during which no audio packets are transmitted or received by the short range wireless communication circuitry.
