摘要： A method for multi-radio coexistence receives historical frequency usage information and historical time usage information from a first radio. The method creates a time and frequency mask by extrapolating the historical frequency and time usage information to future times and frequencies when the first radio will be active and uses the time and frequency mask to schedule a second radio to avoid receiving when the first radio will likely be active. A related apparatus has a collocated radio input for receiving timing usage information, a non-collocated radio input for receiving frequency usage information, and a time and frequency mask generator for creating a time and frequency mask using the timing usage information and the frequency usage information. The method and apparatus predicts collocated and non-collocated radio activity in both the time and frequency dimensions to reduce interference among radios operating in overlapping or adjacent frequency bands.

摘要： A method, a personal area network device operating as a slave, and a short range communications device operating as a slave are disclosed. A data storage 208 may store at least one protocol-specific channel criterion for a connection with a master short range communication device 104. A short range transceiver 108 may execute a preliminary device scan of a scanning set of communication channels for radio frequency energy. A processor 204 may decide to execute a full device scan based in part on the protocol-specific channel criterion.

摘要： A frequency hopping wireless communication device including a controller configured to evaluate channels received by the wireless receiver for interference and to identify channels subject to interference as being unavailable for use by the wireless communication device. The controller is also configured to re-evaluate channels identified as being unavailable for use by the wireless communication device after expiration of a channel assessment time-out interval, and to dynamically change the channel assessment time-out interval based on location or mobility of the wireless communication device.
