Abstract: Methods and systems for enhanced 2-wire and 3-wire WLAN Bluetooth coexistence solution may include determining whether adaptive frequency hopping is active in a Bluetooth communication device. If the adaptive frequency hopping is active, handshaking with a collocated non-Bluetooth communication device may be disabled. The collocated non-Bluetooth communication device may be a wireless local area network communication device. If the adaptive frequency hopping is inactive, handshaking with the collocated non-Bluetooth communication device may be enabled. If the adaptive frequency hopping is inactive, the Bluetooth communication device may initiate handshaking prior to transmitting data. If the adaptive frequency hopping is inactive, the Bluetooth communication device may also respond to the handshaking initiated by the collocated non-Bluetooth communication device. The handshaking may be executed via a 2-wire Bluetooth/WLAN coexistence interface or a 3-wire Bluetooth/WLAN coexistence interface.

Abstract: A method for frequency separation for multiple Bluetooth communication devices on a single platform may comprise determining initial frequencies to be utilized by a plurality of Bluetooth communication devices residing on a single host device. A first portion of the determined initial frequencies may be assigned to a first of the plurality of Bluetooth communication devices. At least a second portion of the determined initial frequencies selected from a remaining portion of the determined initial frequencies may be assigned to at least a second of the plurality of Bluetooth devices. Determination may be made based on those determined initial frequencies that have been interfered with by other wireless communication devices. At least a portion of these frequencies that have been interfered with may be eliminated from the determined initial frequencies. The eliminating may be done dynamically and the determined initial frequencies may be re-assigned based on the eliminating.

Abstract: A method and system sharing a Bluetooth processor for FM functions are provided. The single chip may comprise an integrated Bluetooth radio, an integrated FM radio, and processor system. A processor in the processor system may be utilized for Bluetooth and FM data processing and may time multiplex between the Bluetooth and FM data processing based on interrupt signals. The processor may operate in a low power mode based on a clock signal generated from a low power oscillator. When a Bluetooth interrupt signal is received, the processor may enable Bluetooth data processing that may be based on a Bluetooth clock signal. When an FM interrupt signal is received, the processor may enable FM data processing that may be based on an FM clock signal. When data processing is complete, the processor may return to the low power mode operation.
