In accordance with some embodiments, one or more low-power responder nodes may be utilized to provide better and lower cost coverage for fine timing measurement (FTM) requests. By advertising its availability to receive and respond to FTM requests, a low-power responder node may enter a low-power or deep sleep mode during times of unavailability. A low-power responder node may be powered by a battery, reducing the cost and deployment of nodes in a location determination network.
