    摘要: A wireless local area network (WLAN) device transmits a header over an air interface, at a first modulation rate. The header may include an indication of a second modulation rate that will be used to transmit a consolidated payload. In one embodiment, the header includes information that enables a receiver to determine when an end of each of the multiple data units will occur. The device further transmits the consolidated payload at the second modulation rate. The consolidated payload includes multiple data units. In one embodiment, the consolidated payload includes information that enables the receiver to determine when an end of each of the multiple data units will occur.

    摘要: A wireless local area network (WLAN) device transmits multiple data packets within a data burst. In various embodiments, after the first packet is transmitted, subsequent packets are transmitted before expiration of an Interframe Space (IFS). The subsequent packets may have a full-length preamble, a partial preamble or no preamble at all.

    摘要: A city model generation process. A city model is generated using information about an actual city. A roadway database including segments of roadways is used to generate a city model having grid points corresponding to intersections between the roadway segments. A type of roadway determined from the roadway database information is associated with sets of grid points defining a single roadway. Elevation data is added to the city model using a topographic database. Features, such as a road profile, are added to the roadway using the type. Photographic and zoning information is used to further refine the type of a roadway with a subtype corresponding to features of buildings that may be associated with the roadway. Generic building models and features are associated with the roadways based on the subtypes. Landmark building models are added to the city model to complete the city model.

    摘要: In a communications packet directed to multiple addresses and having a directory of the addresses in order of transmission, a device receiving the packet may use the directory to help determine when the last frame in which the device has an interest is received, and then enter a low power mode for the remainder of the packet reception. The device constructing the packet for transmission may arrange the frames in a manner that promotes overall power savings in the group of addressed devices.
