Classification: CPC G  H  Y | IPC H

Claim 7:
8. A method comprising:
during a first time period:
generating a response schedule for a first asset tag, the response schedule defining:
a first trigger time for transmitting a first unicast trigger;
a first wake window intersecting the first trigger time; and
a second wake window associated with a motion sensor signal;

at a first node in a set of nodes:
broadcasting a configuration message, comprising the response schedule, to the first asset tag via a configuration channel;

at the first asset tag:
in response to absence of configuration data, transitioning a transceiver of the first asset tag to the configuration channel;
receiving the configuration message via the configuration channel;
configuring the first asset tag based on the configuration message; and
in response to a time duration until the first wake window exceeding a threshold time duration, entering a sleep mode; and

during a second time period:
at the first asset tag:
in response to receiving the motion sensor signal from a motion sensor in the first asset tag:
entering a wake mode for a duration of the second wake window; and
transmitting a first ranging signal via a ranging channel during the second wake window; and

in response to transmitting the first ranging signal, entering the sleep mode; and

at the set of nodes:
receiving the first ranging signal; and

deriving a first location of the first asset tag based on instances of the first ranging signal received by the set of nodes.
