<p>Processing associated with ranging operations is shifted from a first apparatus to a second apparatus. For example, upon sampling a received ranging signal (e.g., a pulse) from the second apparatus, the first apparatus does not process the ranging signal to identify a relatively precise time of arrival estimate. Instead, the first apparatus sends sample data (e.g., representative of the power and/or magnitude of the received signal) and associated timestamp information to the second apparatus. The second apparatus processes the received sample data and timestamp information to determine the time of arrival estimate on behalf of the first apparatus. The second apparatus then uses this time of arrival estimate to determine the distance between the apparatuses.</p> |
