  • Patent number: 11395225
    Abstract: A method for a first network device involves transmitting, to one or more second network devices, an uplink message that includes an indication of a receive window time interval, and may also include an indication of a request for a downlink message. The method also involves initiating a scheduled receive mode that causes the first network device to transition the first network device to a first power state, and perform a receive window procedure after the receive window time interval has elapsed. The receive window procedure includes transitioning the first network device to a second power state and listening for the downlink message for a duration of time. The method further involves determining that an expiration condition has been met while the first network device is in the scheduled receive mode. Additionally, the method involves terminating the scheduled receive mode upon determining that the expiration condition has been met.

  • Patent number: 11128501
    Abstract: To more efficiently compensate for modulation imbalance, a mobile device modulates and demodulates a calibration tone and generates digital data representing modulation imbalance effects on the calibration tone. Using digital data enables modulation imbalance effects to be quickly estimated using digital signal processing techniques, increasing the number of estimates of modulation imbalance effects calculated. The modulation imbalance estimates are used to refine one or more compensation parameters which are applied to transmitted and/or received signals to compensate for errors caused by modulation.

  • Patent number: 11076438
    Abstract: A network node of a local area wireless network preferentially tries to connect with a first node having the primary connection relationship with the network node in a first connection time window; when the network node fails to connect with the first node under a predetermined condition, the network node tries to connect with a second node having the backup connection relationship with the network node in a second connection time window. After the network node is connected with and finishes communicating with the first or second node, the network node enters into standby or dormancy state and tries to establish connection in a subsequent first connection time window or a second connection time window. By using priority or backup routing method and setting connection time window, the power consumption management and networking management mechanism of each node of the network are simplified. Each network node can operate at a low power consumption level.

  • Patent number: 10911897
    Abstract: A system for automatically ascertaining the location of wireless functional devices, such as lights and switches, in a building. Information from the devices is generated by receipt of electromagnetic signals from other devices, to calculate a best fit for the relative location of the devices in relation to each other. Preferably a map of the building is adduced to refine the location process, for instance by tying the location of a light switch to a wall or a light to a ceiling. The information is used to ascertain that, for example, two devices are in the same room and can be associated with each other. Account can be taken of variable features of the building such as partition walls, to update device settings. There is thus no need to survey the building manually.

  • Patent number: 10476548
    Abstract: Communications systems containing an electrically-isolated Push-To-Talk (EI-PTT) device are described in this application. The communication systems contain multiple radios, a microphone/headset, and a centralized power supply. The systems also contain an EI-PTT device which reduces or eliminates noise that can disrupt the audio transmission. The EI-PTT device allows an operator or user of the communication system to actuate a button which remotely switches the radio from receive mode to transmit mode. This allows multiple users to listen (receive) to communication traffic on the same frequency at all times, but only speak (transmit) on the frequency while activating the EI-PTT device. Unlike other PTT devices which electrically tie the ground signals inside the device, the EI-PTT devices electrically isolate the ground signals to reduce the problem of noise coupling. Other embodiments are described.

  • Patent number: 9088308
    Abstract: In an up-converter path of a transmitter, wide-band signal system like direct conversion WiGig, a high pass filter (HPF) is placed in the baseband path after the low pass filter (LPF) but before the mixers. The baseband signal of WiGig can have a bandwidth of 800 MHz. The HPF removes the frequencies from 0-40 MHz from the baseband signal and degrades the overall signal of the baseband by a dB or so. However, the frequency pulling is significantly reduced since oscillator frequency and Radio frequency (RF) transmitter frequencies after conversion become further separated when compared a system using to the conventional approach. This causes the injected signal to fall outside the locking range of the oscillator. The concern of substrate coupling is reduced and allows for a reduction in the physical distance between the oscillator and the mixer and reduces a shift in the desired target frequency of operation.

  • Patent number: 9084201
    Abstract: Systems and methodologies are described that facilitate power headroom management in a wireless communication system. As described herein, a predefined relationship between locations along a system frequency band and corresponding power backoff parameters is utilized to minimize spurious emissions outside the system frequency band and/or excessive interference by, for example, associating locations near one or more edges of the permitted frequency band with substantially high power backoff parameters. As further described herein, the predefined relationship can be known a priori to the base station and the mobile terminal.

  • Patent number: 9036514
    Abstract: Systems and methods for combining signals from multiple active wireless receivers are discussed herein. An exemplary system comprises a first downconverter, a phase comparator, a phase adjuster, and a second downconverter. The first downconverter may be configured to downconvert a received signal from a first antenna to an intermediate frequency to create an intermediate frequency signal. The phase comparator may be configured to mix the received signal and a downconverted signal to create a mixed signal, compare a phase of the mixed signal to a predetermined phase, and generate a phase control signal based on the comparison, the downconverted signal being associated with the received signal from the first antenna. The phase adjuster may be configured to alter the phase of the intermediate frequency signal based on the phase control signal. The second downconverter may be configured to downconvert the phase-shifted intermediate frequency signal to create an output signal.
