Abstract: Disclosed are methods, systems and devices for obtaining a measurement of a range between two devices. For example, wireless stations may obtain a measurement of range between the wireless stations based, at least in part, on an exchange messages such as fine timing measurement (FTM) messages. In a particular implementation, FTM messages may be received at a transceiver device in a burst of FTM messages from a responding wireless station. An acknowledgement messages may be transmitted to the responding wireless station in response to receipt of the FTM message.

Abstract: A method and apparatus to save power in a soft access point for a network. If no network traffic is detected for an integral number of TBTT (Target Beacon Transmission Time) intervals immediately prior to a current TBTT interval, and if no network traffic is detected for a first time slot in the current TBTT interval, then the soft access point sends a CTS (Clear-to-Send) packet addressed to itself to quiet the network for a second time slot and enters a low power mode for the second time slot. At the beginning of a third time slot, the soft access point puts itself into an active mode and monitors network traffic.

Abstract: A wireless device implements power saving logic for two or more wireless clients that concurrently communicate on a shared wireless channel (single channel concurrency). When one of the wireless clients transitions from power save mode to active mode (e.g., in response to a beacon signal), the power saving logic causes the other wireless client(s) to transition to active mode as well. Each wireless client ‘awakened’ in this manner transmits a NULL frame having a power management bit set to a logic ‘0’ value to an associated access point (AP), thereby indicating its active status to the associated AP. As a result, all of the wireless clients may concurrently receive buffered data from their associated APs on the shared wireless channel. If the ‘awakened’ wireless client(s) do not need to transition to active mode in response to their next received beacons, power consumption of the wireless device is advantageously reduced.
