摘要： A network device includes a first physical layer (PHY) module, a second physical layer (PHY) module, and a security module. The first PHY module is configured to operate in a first frequency band. The second PHY module is configured to operate in a second frequency band. The security module is configured to establish security for the first frequency band responsive to the network device operating in the first frequency band. The security module is further configured to establish security for the second frequency band prior to the network device switching operation from the first frequency band to the second frequency band.

摘要： A method for generating signals to be transmitted within a basic service set (BSS) channel, where a set of component channels is collectively coextensive with the BSS channel, includes determining that a first duplicate, in frequency, of a low bandwidth mode data unit will be located at an edge of the BSS channel. Each duplicate includes orthogonal frequency division multiplexing (OFDM) tones and has a bandwidth less than the narrowest channel of the component channels. The OFDM tones in each duplicate include one or more data tones, one or more pilot tones, and one or more guard tones. The method also includes generating a transmission signal comprising the duplicates, at least in part by scaling down at least one data tone, and/or zeroing out at least one data tone, of the first duplicate in response to determining that the first duplicate will be located at an edge of the BSS channel.

摘要： In a method for generating a data unit, a signal field is generated to include a first subfield having one of: a length indication to indicate a number of bytes in a data portion of the data unit, or a duration indication to indicate a number of OFDM symbols in the data portion of the data unit and a second subfield to indicate whether the first subfield includes the length indication or the duration indication. When the first subfield includes the length indication, one or more padding bits are added to a set of information bits according to a first padding scheme. When the first subfield includes the duration indication, one or more padding bits are added to the set of information bits to according to a second padding scheme. Padded information bits are encoded, and the data unit is generated to included the encoded information bits.

摘要： A system including a physical layer module and a processing module. The physical layer module is configured to communicate at a first data rate via a channel, where the channel includes (i) a first sub-channel and (ii) a second sub-channel of the channel, to receive a first packet including a first preamble transmitted at the first data rate via (i) the first sub-channel and (ii) the second sub-channel, and to receive a second packet including a second preamble transmitted at a second data rate via (i) the first sub-channel or (ii) the second sub-channel, where the second data rate is less than the first data rate. The processing module is configured to process (i) the first preamble transmitted at the first data rate and (ii) at least a portion of the second preamble transmitted at the second data rate.
