1. A method for communication, comprising:
simultaneously transmitting over a wireless network from a first station to a second station at least first and second request-to-send (RTS) frames in different, respective first and second frequency channel;
receiving at the first station first and second clear-to-send (CTS) frames transmitted in the first and second frequency channels, respectively, by the second station over the wireless network in response to the first and second RTS frames, wherein the first and second CTS frames are coherent with one another due to being generated using a common frequency synthesizer in the second station; and
estimating at least one property associated with the first station by processing information extracted from both the first and second received CTS frames, while treating the first and second CTS frames as parts of a single, broadband transmission due to a coherence of the first and second CTS frames.
