8 results about "Frequency assignment" patented technology

Frequency assignment is the authorization of use of a particular radio frequency. In Article 1.18 of the International Telecommunication Union's (ITU) Radio Regulations (RR), the process is defined as "Authorization given by a frequency administration for a radio station to use a radio frequency or radio frequency channel under specified conditions».

Optical frequency spectral optimization in dense wavelength division multiplexing (DWDM) flex grid system

Novel tools and techniques are provided for implementing optical frequency spectral optimization in dense wavelength division multiplexing (“DWDM”) flex grid systems. In various embodiments, based on a determination that one or more gaps of optical spectrum exist in a range of optical spectrum that contains one or more media channels that support transmission of corresponding one or more first signals, a computing system may determine a network wavelength service frequency assignment for shifting frequency of at least one media channel among the one or more media channels to optimize one or more spacings among the one or more media channels in the range of optical spectrum for supporting transmission of one or more second signals; and may cause one or more optical signal devices to shift a center frequency of each of the at least one media channel, based on the determined network wavelength service frequency assignment.

Frequency awarding method based on GEO communication satellite beacon signals

This invention provides a frequency assignment method based on GEO communication satellite beacon signals. The standard time-frequency signal output from the NTSC clock array is used as the time-frequency reference signal for the ground control station. The ground control station transmits control signals modulated with the standard time-frequency signal to the GEO satellite in a self-transmitting and self-receiving mode. The GEO satellite receives the control signals from the ground control station, mixes them with an onboard high-stability crystal oscillator, and then feeds them back to the ground control station, while also sending beacon signals to the user terminal. The ground control station obtains the satellite clock offset based on the signal fed back from the GEO satellite and sends it to the user terminal. The user terminal obtains its standard frequency based on the satellite clock offset sent by the ground control station, the beacon signal sent by the GEO satellite, and the satellite orbit sent by the passive orbit determination system. This invention can not only provide a basis for satellite ground control stations to search for, measure, and track satellites, but also provide precise frequency assignment services to ground users with known locations.
