Abstract
A system includes a node configured to: listen to a first two-way timing and ranging (TWTR) interrogation message and a first TWTR response message communicated between a first node pair during a first time interval; determine a first time difference of arrival (TDoA) between the first TWTR interrogation message and the first TWTR response message; determine a first boundary of position (BoP); and based at least on the first BoP, determine position information and/or time information of the node without the node transmitting any TWTR interrogation message or any TWTR response message.
