摘要： Logic may comprise hardware and/or code to select a narrow band from a wider channel bandwidth. Logic of communications between devices may select, e.g., a 1 or 2 MHz sub-channel from a wider channel bandwidth such as 4, 8, and 16 MHz and transmit packets on the selected 1 or 2 MHz channel. For instance, a first device may comprise an access point and a second device may comprise a station such as a low power sensor or a meter that may, e.g., operate on battery power. Logic of the devices may facilitate a frequency selective transmission scheme. Logic of the access point may transmit sounding packets or control frames across the sub-channels of the wide bandwidth channel, facilitating selection by the stations of a sub-channel and subsequent communications on the sub-channel between the access point and the station.
摘要翻译：逻辑可以包括从更宽的信道带宽中选择窄带的硬件和/或代码。设备之间的通信逻辑可以从诸如4,8和16MHz的更宽的信道带宽中选择例如1或2MHz的子信道，并在选择的1或2MHz信道上发送分组。例如，第一设备可以包括接入点，并且第二设备可以包括诸如低功率传感器或可以例如对电池电力进行操作的仪表的站。设备的逻辑可以促进频率选择性传输方案。接入点的逻辑可以在宽带宽信道的子信道上发送探测分组或控制帧，便于站点选择子信道，并在接入点和站之间的子信道上进行随后的通信。

摘要： Certain embodiments of the invention may include systems, methods, and apparatus for a short beacon in low rate Wi-Fi communications. According to an example embodiment of the invention, a method is provided for generating a short beacon. The method can include generating a short beacon frame for transmission at a selectable beacon interval. The short beacon frame includes: a beacon timestamp field, a service set identifier (SSID) field, and one or more capability fields; and generating a traffic indicator map (TIM) frame for transmission at a selectable TIM interval. The TIM frame includes a TIM timestamp field, a check beacon field, and a TIM; and converting the short beacon frame and the TIM frame for wireless transmission over a hardware transmission medium.

摘要： Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz and lower frequency bands. In many embodiments, the physical layer logic may implement repetition logic to repeat portions of the data streams to increase the ability of a receiving device to detect and decode the data streams. In some embodiments, the repetition logic may comprise a preamble repeater to repeat the training and/or signal fields. In further embodiments, the repetition logic may comprise a payload repeater to repeat the payload one or more times. Other embodiments comprise a receiving device comprising a correlator to correlate the repeated preamble symbols to detect a communication from a transmitting device. The receiving device may also comprise correction logic to correct data streams from the communications signal based upon repetitions of the payload in the data streams.
