1. A method comprising:
for each pair of nodes in a set of nodes:
at each node in the pair of nodes:
transmitting an outbound synchronization signal;
receiving a self-receive signal associated with the outbound synchronization signal; and
receiving an inbound synchronization signal;
based on the self-receive signal and the synchronization signal received by each node in the pair of nodes:
calculating a pairwise time offset between the pair of nodes; and
calculating a pairwise distance between the pair of nodes; and
at each node in the set of nodes, receiving a localization signal, transmitted by a device; and
calculating a location of the device relative to the set of nodes based on the localization signal received at each node in the set of nodes, the pairwise time offset and the pairwise distance.
