    Abstract: A wireless communication device (WCD) generates and transmits wireless broadband signals (WBS) at a power level that is below a spurious emissions mask such that the transmitted WBS occupy a designated frequency spectrum band. The WCD transmits duty cycle bursts of the WBS and determines range, position and/or movement based on the transmitted burst of the WBS. A bandwidth of the wireless broadband signals may occupy approximately 800 MHz within a range of 0 Hz to 1 GHz. The transmit power utilized for transmitting the WBS may be spread over a bandwidth of approximately 300 MHz within the 800 MHz bandwidth. The spreading results in a power spectral density of the transmitted WBS approximating thermal noise at a distance of approximately 3 meters. A course range may be determined utilizing wireless signals other than the transmitted bursts and a fine range may be determined utilizing the transmitted bursts.

    Abstract translation: 无线通信设备（WCD）以低于杂散发射掩码的功率电平产生和发送无线宽带信号（WBS），使得发送的WBS占据指定的频谱带。 WCD发送WBS的占空比脉冲串，并且基于WBS的传输脉冲串来确定范围，位置和/或移动。 无线宽带信号的带宽可以在0Hz至1GHz的范围内占用大约800MHz。 用于发送WBS的发射功率可以在800MHz带宽内扩展到大约300MHz的带宽。 扩展导致传输的WBS的功率谱密度近似于距离约3米的热噪声。 可以利用除了所发送的脉冲串之外的无线信号来确定路线范围，并且可以利用所发送的脉冲串来确定精细范围。

    Abstract: A GNSS receiver communicates with any connectivity device, such as a WiFi device that is, in turn, in communication with a wired network having access to the DTI timing. Such connectivity devices may set their timing and frame synchronization to the DTI and thus serve as Geoposition beacons, thereby enabling the GNSS receiver to accurately determine its position. The GNSS receiver may also use the DTI timing supplied by such a network to perform relatively long integration time so as to achieve substantially improved sensitivity that is necessary for indoor Geopositioning applications. Furthermore, the GNSS data, such as satellite orbital information, may also be propagated by such devices at high speed. By providing this data to the GNSS receivers via such connectivity devices in a rapid fashion, the GNSS receivers are enabled to receive the transmitted data associated with the satellite without waiting for the GNSS transmission from the satellites.

    Abstract: A wireless communication receiver includes a multitude of look-up tables each storing a multitude of DC offset values associated with the gains of an amplification stage disposed in the wireless communication receiver. The entries for each look-up table are estimated during a stage of the calibration phase. During such a calibration stage, for each selected gain of an amplification stage, a search logic estimates a current DC offset number and compares it to a previous DC offset estimate that is fed back to the search logic. If the difference between the current and previous estimates is less than a predefined threshold value, the current estimate is treated as being associated with the DC offset of the selected gain of the amplification stage and is stored in the look-up table. This process is repeated for each selected gain of each amplification stage of interest until the look-up tables are populated.

    Abstract: Methods and systems for location determination and navigation using textual information may comprise capturing images of sources of textual information in the vicinity of a wireless communication device (WCD). Text may be extracted from the sources and a position of the WDC may be determined based on a comparison of the extracted text a stored database of textual information. An orientation of the text may be sensed and may be utilized with the extracted text and determined distances from the sources for the position determining. Locations of the sources and/or the captured images may be stored in the database. An instruction to capture images in a different orientation may be received when the positioning does not meet an accuracy requirement. A distance from the sources of textual information may be determined based on known optical properties of a camera in the WCD, such as focal length and/or and focus setting.

    Abstract: A network device (e.g., a cable modem) may support a normal mode of operation and a sleep mode of operation. While in the normal mode, a PHY of the network device may process a received signal to recover MPEG-TS packets, and convey the MPEG-TS packets to other components of the network device for further processing. While in the sleep mode, the PHY may process received MPEG-TS packets having a particular packet identifier and drop received MPEG-TS packets not having the particular packet identifier. The PHY may control transitions between the normal mode and the sleep mode in response to received signals having particular physical layer characteristics. The PHY may demodulate a received signal to recover an MPEG-TS packet; descramble portions of the MPEG-TS packet; inspect portions of the MPEG-TS packet; and control a mode of operation of the network device based on the contents of the MPEG transport stream.
