摘要： Systems and techniques relating to wireless local area network devices include a method involving generating a baseband signal indicative of one or more symbols, modulating the baseband signal at a carrier frequency to produce a modulated signal, transmitting the modulated signal via a wireless channel, and providing a clock signal to control, in the baseband signal, a duration of the one or more symbols. Providing the clock signal can include selectively using a first clock frequency to generate a first baseband signal having a first bandwidth. Providing the clock signal can include selectively using a second, lower clock frequency to generate a second baseband signal having a second, lower bandwidth. The second clock frequency can be used to extend a wireless communication range of the wireless channel.

摘要： A method of generating packets for transmission in a wireless communication system, wherein each packet includes a SIG field that includes a first SIG subfield, includes generating a data packet and a null data packet. Generating the data packet includes generating information bits of the first SIG subfield of the data packet and generating the data portion of the data packet. The information bits of the first SIG subfield of the data packet indicate, to a receiving device, a length corresponding to a data portion of the data packet. Generating the null data packet includes generating information bits of the first SIG subfield of the null data packet. The information bits of the first SIG subfield of the null data packet indicate, to a receiving device, a first physical layer (PHY) parameter value associated with the null data packet. The first PHY parameter value is not a length value.
