  • Patent number: 11432367
    Abstract: Hybrid self-organizing networks. One example system includes a cellular network and a mobile satellite network. The cellular network includes a cellular base station configured to perform at least one cellular interference mitigation measure. The cellular network is configured to provide wireless communications in a first frequency band within a first deployed area. The mobile satellite network includes a mobile satellite network terminal configured to perform at least one satellite interference mitigation measure. The mobile satellite network is configured to provide wireless communications in the first frequency band within a second deployed area separated from the first deployed area by a first standoff distance. Performance of one or both of the at least one cellular interference mitigation measure and the at least one satellite interference mitigation measure results in a second standoff distance that is less than the first standoff distance.

  • Publication number: 20070021062
    Abstract: A communication device may include a power source, a transmitter configured to transmit radio frequency signals to a satellite via a satellite-based network and a receiver configured to receive radio frequency signals from the satellite via the satellite-based network. The communication device may also include logic configured to receive power mode control information from a handset coupled to the communication device. The logic may also be configured to provide power to components of the communication device from the power source based on the power mode control information.

  • Patent number: 5276409
    Abstract: An autotuning combiner particularly for use in combining signals for radio telephony transmission. The combiner has a series of filter cavities each with an adjuster for fine-tuning the cavity to an input carrier signal. The combiner cavities are stabilized from positional drift in the absence of a carrier signal by means of a mechanical brake which holds the adjuster or a pilot signal generator which simulates the absent carrier signal.

  • Patent number: 4206420
    Abstract: An improved phase-locked loop includes a phase detector, active loop filter and a VCO, in conventional phase-locked loop relationship. In addition, a positive feedback path couples active loop filter output to active loop filter input. In the absence of loop lock, the positive feedback provided by the positive feedback path satisfies the conditions necessary for the production of an oscillating output from the active loop filter circuit. The oscillating output generated by this "oscillator" drives the VCO in a sweeping action allowing the loop to acquire signals outside of its normal capture range. On capture, phase detector output provides an additional negative feedback path which overrides the effect of the positive feedback path and therefore, oscillations cease and the loop locks. The positive feedback path can comprise a relatively simple passive frequency selective circuit.
