    摘要： Embodiments allow a wireless device configured to work with the 802.11n/ac standard to work in the communication bands where 802.11p devices operate with little change. Embodiments may receive signals using a receiver adapted for the wider bandwidth 802.11n/ac signals. Embodiments may also increase the sensitivity of the receiver to reduce the likelihood of missing the presence of a lower bandwidth 802.11p signal. When a signal is detected, embodiments may process the incoming signal as if it were an 802.11n/ac signal while also processing incoming signal samples in a way that effectively narrows the receiver bandwidth to identify whether an 802.11p signal is present. If the device detects the presence of an 802.11n/ac signal, it may terminate the 802.11p signal processing and proceed with normal 802.11n/ac operation. If the device detects the presence of an 802.11p signal, it may terminate 802.11n/ac processing and trigger collision avoidance processes.

    摘要： Embodiments of device-to-device (D2D) discovery, authentication, and connection techniques are generally described herein. In an example, a device-to-device connection establishment technique may be performed directly between peer-to-peer wireless communication devices without obtaining authentication information from a cloud network or an external service. The device-to-device connection establishment technique may include a transmission of a discovery request to available devices, a transmission of a response from available devices including authentication data, and a verification of the authentication data. The authentication data may include previously stored image data associated with a device or human user associated with a device. In further examples, image processing and image recognition techniques may be used to verify a particular device or human user associated with a device.

    摘要： An approach is provided for defining a 1MHz preamble of a packet. The approach involves determining a preamble sequence of a packet, the preamble sequence having a determinable length. The approach also involves causing, at least in part, the preamble sequence to be divided into a predetermined number of blocks. The approach further involves causing, at least in part, a mathematical operation and a summation over the predetermined number of blocks and a corresponding number of received blocks. The approach also involves causing, at least in part, the summation to be maximized to determine the preamble sequence corresponds to one of a first bandwidth or a second bandwidth, the second bandwidth being greater than the first bandwidth, to determine a type of the packet.

    摘要： A communication unit operates in a wireless-networking environment and maintains a mapping for active channels and associated network identifiers. The communication unit may associate with a wireless network using the mapping for one or more of the active channels having a selected network identifier. For associations and reassociations with wireless networks, the communication unit may selectively scan the channels having mapping stored in a table to more quickly identify active channels and thereby reduce scan time. In some embodiments, an access point may perform channel-width measurements and radar detection using the bitmap.

    摘要： Logic may comprise a single phase tracking implementation for all bandwidths of operation and the logic may adaptively change pre-defined and stored track parameters if the 5 receiving packet is 1 MHz bandwidth. Logic may detect a packet and long training fields before performing a 1 MHz classification. Logic may auto-detect 1 MHz bandwidth transmissions by a property of the long training field sequences. Logic may auto-detect 1 MHz bandwidth transmissions by detecting a Binary Phase Shift Keying (BPSK) modulated first signal field symbol rather than the Quadrature Binary Phase Shift Keying (QBPSK) associated with the 2 10 MHz or greater bandwidth transmissions. Logic may perform an algorithm to determine an estimated phase correction value for a given orthogonal frequency division multiplexing symbol and several embodiments integrate this value with an intercept multiplier that may be 0.2 for 1 MHz transmissions and, e.g., 0.5 for 2 MHz or greater bandwidth communication.
