  • Patent number: 11832208
    Abstract: Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A location server can estimate a coarse location of a mobile device using a localization technique other than a UWB localization technique. The localization technique can involve multiple wireless access points or other radio devices. The location server can define an area around the coarse location to identify a set of candidate anchors for UWB ranging. The set of candidate anchors can be disposed within the area and include at least a subset of the radio devices. The location server can modify the set of candidate anchors to create a modified set of candidate anchors that includes only UWB-enabled devices. The location server can select a primary anchor from the modified set of candidate anchors and send a command to cause a UWB ranging procedure to be initiated between the primary anchor and the mobile device.

  • Patent number: 11817898
    Abstract: Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications.

  • Patent number: 11777539
    Abstract: A transmit power optimization and rate-control system includes a transmitter circuit having one or more power amplifiers transmit radio-frequency (RF) signals at a transmission (Tx) rate and a Tx power level.

  • Patent number: 11736167
    Abstract: A method for time-domain allocation of radio resources in a communication system using beamforming comprises obtaining of a list of wireless devices to be served. Subcarriers and beam directions of a multi-directional beamform are allocated to wireless devices of the list. The beam direction for each wireless device covers a position of that wireless device. The number of allocable subcarriers is limited to fulfil a beam-forming power constraint. This beam-forming power constraint is that the total power of allocated subcarriers, when each allocated subcarrier provides a same effective isotropic radiated power density for a wireless device as would be provided by a single-directional beamform, is within a predetermined power budget.
