Abstract
The disclosure relates to time-of-flight (TOF) positioning and device location within a wireless networks using a hybrid combination of Bluetooth Low Energy (BLE) and Wi-Fi signaling. In one exemplary embodiment, a hybrid responder engages in BLE discovery and negotiation with a mobile device seeking its location. The hybrid responder may engage its WiFi platform only to conduct the FTM procedure. By keeping the WiFi platform in deep sleep or Off mode, the hybrid responder can gain significant power savings.
