    Abstract: An electronic device configures two or more virtual responders associated with different subsets of capabilities of a physical responder in the electronic device, where the physical responder comprises a radio-frequency (RF) transceiver and multiple antennas, and where a given virtual responder corresponds to the RF transceiver and a given antenna. Then, the electronic device performs, based at least in part on wirelessly communication with a second electronic device and using at least the virtual responders, measurements on wireless signals from the second electronic device to the electronic device, where the measurements correspond to a time of flight of the wireless signals. Next, the electronic device determines, based at least in part on the measurements, a range between the electronic device and the second electronic device, where the determination uses the measurements from different virtual responders to correct for an environmental condition and/or increase an accuracy of the determined range.

    Abstract: Techniques are provided for transmitting a secure frame by a wireless device. For example, the wireless device may determine a location within a data sequence of a secure frame to puncture the data sequence with a puncture. The wireless device may then generate the secure frame that includes the punctured data sequence and transmit the secure frame to a second wireless device. The second wireless device may then authenticate the secure frame based at least in part on the location of the puncture within the punctured data sequence.
