  • 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: 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.
