BLUETOOTH LOW ENERGY BASED WIRELESS AIR-TIME MANAGEMENT SYSTEM

Abstract: disclosed are techniques to setup and use a ble based wireless network between central devices of multiple piconets to exchange information to coordinate air-time usage by the piconets of the central devices. the information exchanged may include channel maps that indicate frequency channels that are available for use by the respective piconets, slot availability masks that indicate future air-time slots for use by the respective piconets based on a common time reference, and other meta information used to coordinate regulation of air-time usage. the multiple central devices may collaboratively regulate their respective air-time usage based on the exchanged information to reduce the potential for air-time clash. in one aspect, the central devices may use the periodic advertising with response (pawr) protocol in ble to exchange future air-time usage information. the timing of periodic advertising packets may provide a time reference for the multiple central devices to coordinate their air-time usage.
