Claim:
1. A non-transitory computer-readable medium having stored therein computer code, which when executed by a networking device functioning as a beamformer in a wireless local area network (WLAN), cause the networking device to perform a set of operations to improve a sounding procedure where a steering matrix or a compressed beamforming report is utilized by the beamformer using feedback from at least one beamformee, the steering matrix or compressed beamforming report to determine a spatial path for transmission from the beamformer to a set of beamformees in the WLAN, the set of operations comprising: selecting, by the beamformer, a bandwidth for a sounding frame used to perform the sounding procedure; generating, by the beamformer, the sounding frame at the selected bandwidth using a mode of operation from a plurality of modes of operation, wherein each mode of operation corresponds to a frame format and the mode of operation used to generate the sounding frame has a minimum pilot tone density amongst frame formats of the plurality of modes of operation with the selected bandwidth; and transmitting the sounding frame to the set of beamformees.
