Examples described herein provide ranging by a network device during a beacon interval. Examples described herein may discover, by a network device during a first beacon interval, a plurality of APs in a network that are capable of ranging and a received signal measurement of each of the plurality of APs. Examples described herein may select, by the network device, an AP with a strongest received signal measurement among the plurality of APs, determine, by the network device, whether the selected AP is available for ranging, and based on a determination that the selected AP is available for ranging, initiate, by the network device during a second beacon interval, ranging measurements with the selected AP to generate a ranging result. Examples described herein may, based on the ranging result, resolve locations of the plurality of APs.
