Claim:
1. A wireless communication device capable of wireless communication with a plurality of external devices, the wireless communication device comprising: an antenna setting module configured to set a plurality of antenna modes for the wireless communication with the plurality of external devices, wherein the plurality of antenna modes include selected ones of at least: a first antenna radiation mode, and a second antenna radiation mode, and wherein the antenna setting module sets the plurality of antenna modes based on information received from the plurality of external devices; and a framing module configured to generate data for transmission to the plurality of external devices via radio frequency (RF) signaling in accordance with the plurality of antenna modes set by the antenna setting module, wherein at least one frame of the data includes a channel estimation field split into a first sub-field portion transmitted via the first antenna radiation mode and a second sub-field portion transmitted via the second antenna radiation mode; wherein the antenna setting module switches between the first antenna radiation mode of the plurality of antenna modes corresponding to a first transmission angle for transmission of the first sub-field portion at the first transmission angle and the second antenna mode of the plurality of antenna modes corresponding to a second transmission angle for transmission of the second sub-field portion at the second transmission angle.
