摘要： Apparatus and methods for communicating and applying training sequences are described herein. For example, provided is a method for generating a short training field (STF) sequence comprising thirty two values or less. The STF sequence can include a first subset of values including zero and non-zero values. The non-zero values can be located at indices of the first subset that are at least a multiple of two, and can be a multiple of four. The STF sequence includes a second subset of zero values that can include all values not included within the first subset. The method further includes transmitting a data unit comprising the STF sequence over a wireless channel. In another example, a method is provided that includes generating a long training field (LTF) sequence comprising thirty two values or less, and transmitting a data unit comprising the LTF sequence over a wireless channel.

摘要： Systems, methods, and devices to enable monitoring of wireless networks are described herein. In some aspects, a low power receiver or a receiver operating in a low power mode scans for signals with a moderate or low duty cycle. If a signal identifying a device or user of the receiver, or a signal indicating that there will be a subsequent data communication, is received, a high power receiver or a receiver operating in a high power mode is activated to receive data communications.

摘要： Systems, methods, and devices for wireless communication. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a receiver configured to receive a wireless signal comprising a packet. At least a portion of the wireless signal is configured to be received over a bandwidth lower than or equal to 1.25 MHz. The packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones. The thirty-two tones correspond to frequency subcarriers within the bandwidth. The thirty-two tones of the at least one OFDM symbol are allocated as: twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone. The apparatus includes a processor configured to evaluate the wireless signal. The processor includes a transform module configured to convert the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode.
