The disclosure generally relates FTM measurements using a network of Access Points (APs) and FTM responders to provide location information to an inquiring mobile device. In one embodiment, the disclosure provides significant power conservation by allowing an AP to communicate with the user equipment (e.g., mobile device) seeking its location. The AP can relay information about availability of an FTM Responder to the user equipment thereby directing the user equipment to transmit its FTM Request directly to the FTM Responder during the Responder's availability window. The disclosed embodiment enable significant power conservation for the FTM Responder thereby extending the battery life of the Responder.
