摘要： In a multi-radio platform that operates in two networks, both the announced beacon intervals and the actual beacon intervals in one network may be periodically increased and decreased in defined amounts so that the beacons will not overlap scheduled communications with the other network. The determination of how much and how often to adjust these beacon intervals may be based, at least partially, on the minimum increments in which the beacons intervals are permitted to be adjusted, and on the scheduled communications intervals of the other network.

摘要： Embodiments may provide a way of communicating via an electromagnetic radiator, or light source, that can be amplitude modulated such as light emitting diode (LED) lighting and receivers or detectors that can determine data from light received from the amplitude modulated electromagnetic radiator. Some embodiments may provide a method of transmitting/encoding data via modulated LED lighting and other embodiments may provide receiving/decoding data from the modulated LED lighting by means of a device with a low sampling frequency such as a relatively inexpensive camera (as might be found in a smart phone). Some embodiments are intended for indoor navigation via photogrammetry (i.e., image processing) using self-identifying LED light anchors. In many embodiments, the data signal may be communicated via the light source at amplitude modulating frequencies such that the resulting flicker is not perceivable to the human eye.
