Range to a wireless communications node and position relative to one or more wireless communication nodes can be determined with a reduced amount of power consumption. In one example, a probe request is sent at a first power level. Probe responses in response to the probe request are listened for. The number of different radios from which a probe response has been received is counted and compared to a threshold. If the count does not exceed the threshold, then a second different probe request is sent. |
