Abstract: An apparatus for communication with a plurality of devices using time divisional multiple access (TDMA) is described. The apparatus includes processing circuitry configured to for a particular duration, scan a first channel for one or more data packets being transmitted over the first channel to determine if the apparatus is experiencing signal interference. In response to determining that the apparatus is not experiencing signal interference, the processing circuitry is configured to output a first beacon at a first time using TDMA, wherein the first time is a predefined interval amount of time after an output time of a most recent beacon previously output by the apparatus. Otherwise, the processing circuitry is configured to output the first beacon at a second time using TDMA, wherein the second time comprises the first time plus-or-minus a time shift period.

Abstract: An apparatus for communication with a plurality of devices using time divisional multiple access (TDMA) is described. The apparatus includes processing circuitry configured to receive a signal from a device of the plurality of devices. The processing circuitry is further configured to determine, using the signal from the device, whether the device is experiencing signal interference. In response to determining that the device is not experiencing signal interference, the processing circuitry is configured to output a superframe including a first beacon at a first time, wherein the first beacon indicates a starting of the superframe. In response to determining that the device is experiencing signal interference, the processing circuitry is configured to output a time-shifted superframe including a second beacon at a second time that is different than the first time, wherein the second beacon indicates a starting of the time-shifted superframe.
