5 results about "Beacon interval" patented technology

Systems and methods for detecting node outages in a mesh network are disclosed. A tracking node in the mesh network detects a set of signals originating from a tracked node in the mesh network. The set of signals includes beacons or communication messages sent by the tracked node. The tracking node determines that a threshold number of beacon intervals have elapsed since a most recent signal was received from the tracked node. The tracking node performs an outage verification based on data received from another node in the mesh network and updates a state of the tracked node. Based on the updated state, the tracking node outputs a probe to the tracked node, which requests a response to the probe. When no response to the probe is received from the tracked node, the tracking node sends an outage alert message to a next topology higher layer of the mesh network.

A procedure (400) comprising the following: Detect (410) by a network device (100) during a first beacon interval, a plurality of access points (APs) on a first channel capable of ranging and receiving signal measurement from each of the plurality of APs on the first channel; Determine, by the network device, a set of APs from the multitude of APs on the first channel that have not yet performed ranging; Select (415), by the network device, one AP with the strongest received signal measurement among the set of APs on the first channel; Determine (420) through the network device whether the selected AP is available for ranging; Based on a determination that the selected AP is available for ranging, the network device initiates (425) ranging measurements with the selected AP on the first channel during a second beacon interval to produce a ranging result; based on the ranging result, Determine (430), by the network device, of locations of the plurality of APs on the first channel, wherein determining the locations of the plurality of APs on the first channel includes estimating the locations of the plurality of APs on the first channel on an AP map.

This disclosure provides methods, components, devices and systems for advanced notification of critical updates. Some aspects more specifically relate to transmission of an indication of a critical update at least a threshold duration prior to the critical update occurring, where the indication of the critical update includes a time at which the critical update is to occur. In some implementations, the time at which the critical update is to occur may be indicated via a difference between a time at which the indication of the critical update is received and the time at which the critical update is to occur, via a quantity of beacon intervals, via an absolute time reference, or any combination thereof. Additionally, or alternatively, the indication of the critical update may include an indication of one or more communication links for which the critical update applies, additional information about the critical update, or both.
