Abstract
Methods, devices and systems for wireless communication generate signals by determining whether legacy devices are within a proximal region of the wireless communication. When at least one legacy device is within the proximal region, a frame is formatted to include a preamble field, a signal field, and a data field. Further, the uncoded bits are encoded according to a coding format. The coding format is determined according to bits in the preamble and applicable sub-field lengths.
