摘要： In a wireless network, the decision of when and whether to send unsolicited polls to a particular mobile wireless device may be made by monitoring communications conditions affecting the ability of the particular device to gain channel access, and sending unsolicited polls if the ability to gain channel access is below a threshold value. Such conditions may include one or more of channel load, device transmission load, collision rate, and number of mobile wireless devices contending for access.

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.

摘要： Methods and systems for communicating in a wireless network may distinguish different types of packet structures by modifying the phase of a modulation constellation, such as a binary phase shift keying (BPSK) constellation, in a signal field. Receiving devices may identify the type of packet structure associated with a transmission or whether the signal field is present by the phase of the modulation constellation used for mapping for the signal field. In one embodiment, the phase of the modulation constellation may be determined by examining the energy of the I and Q components after Fast Fourier Transform. Various specific embodiments and variations are also disclosed.
