Initializing probability vectors for determining a location of motion detected from wireless signals

A system comprising:

• wireless communication devices in a wireless communication network that are configured to exchange wireless signals over wireless links, each wireless link defined between a respective pair of the wireless communication devices;
• and
• one or more processors;
• and
• memory storing instructions that are configured to perform operations when executed by the one or more processors, the operations comprising:
• obtaining a set of motion indicator values associated with a prior time frame, the set of motion indicator values indicating motion detected from the wireless links in the wireless communication network during the prior time frame, each motion indicator value associated with a respective wireless link,
• generating a prior probability vector based on the set of motion indicator values and comprising values for wireless communication devices connected to the wireless communication network during the prior time frame, the values representing a probability of motion at the connected wireless communication devices during the prior time frame,
• selecting the prior probability vector or one of a plurality of initialization probability vectors based on the set of motion indicator values, a configuration of the wireless communication network, or both, and
• using the selected probability vector and a set of motion indicators associated with a second, subsequent time frame to identify a location associated with motion that occurred during the subsequent time frame.
