    摘要: Selection between first and second communication channels of differing bandwidths for communication between communication devices may be chosen by a method, an apparatus, or a computer-readable medium wherein the first channel is employed as a communication channel, a determination is made whether a criterion associated with the communication channel is met, and, if the criterion associated with the communication channel is met, an evaluation of the second channel is performed and one of the first and second channels is chosen to subsequently employ as the communication channel based on the evaluation of the second channel.

    摘要: Systems and techniques relating to wireless communications are described. A described technique includes monitoring a group of wireless channels that are useable by at least a first wireless communication device for wireless communications, receiving one or more beacon signals from one or more second wireless communication devices, identifying, within the group of wireless channels, one or more primary channels on which the one or more beacon signals are received, estimating a traffic load for the one or more identified primary channels, determining, based on the estimated traffic load, whether to use as a primary channel for the first wireless communication device, a channel of the one or more identified primary channels or a channel of the group of wireless channels that is separate from the one or more identified primary channels; and selecting the primary channel for the first wireless communication device based on a result of the determining.

    摘要: In a method for transmitting a data unit in a wireless communication network, a physical layer (PHY) preamble and a media access control layer (MAC) header are generated. In generating the MAC header, a first address field to include a first address and a second address field to include a second address are generated. The first, not globally unique, address indicates a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The second address field indicates the other one of a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The first address field and the second address field are included in the MAC header. The MAC header omits a globally unique address corresponding to the first address of the first address field.

    摘要: The present disclosure provides secure block acknowledgment techniques for use in communication networks. In one embodiment, a method of processing data at a communication device that maintains a receiving window defining a set of information units that the communication device may accept includes receiving an information unit from a transmitting station during a block acknowledgment session with the transmitting station. The information unit includes information indicative of a request for the communication device to adjust the receiving window. The method further includes determining whether the received information unit is encrypted. The method further includes adjusting the receiving window if the received information unit is encrypted.

    摘要: In a method for generating a data unit for transmission in a wireless network, a physical layer (PHY) preamble is generated. In generating the PHY preamble, a first indicator is generated to indicate at least one of (i) whether the data unit includes data offloaded from a mobile telephony network separate from the wireless network, or (ii) whether the data unit (a) was generated by, or (b) is addressed to, a communication device that supports offloading of data from the mobile telephony network to the wireless network. The first indicator is included in the PHY preamble. Additionally, a media access control layer (MAC) header is generated. The data unit is generated to include the PHY preamble and the MAC header. The data unit is then caused to be transmitted.

    摘要: A generic transducer interface includes a hardware connector, such as a pin connector, with connection points for electrically connecting to a transducer, a control, a non-volatile memory for storing firmware used to configure the control, and a wired/wireless communication interface. The firmware indicates pre-assigned functions of the connection points, as well as providing: (a) data processing services, which perform operations on data elements from the transducers to obtain results which are reported to an external host, (b) data reporting and reception services, which include a data reporting protocol for reporting data from the transducers to the host, and a data receiving protocol for receiving data from the host, and (c) transducer management services, which allow retrieval and reconfiguration of transducer-specific properties. Transducer-specific configuration data received from the external host configures the control with the information it needs to act as an interface for a particular transducer.
