Radiocommunication Systems and Services Definitions
A radio-communication service between specified fixed points.
A radio-communication service between mobile and land stations, or between mobile stations (CV).
Land Mobile Services:
A mobile service between base stations and land mobile stations, or between land mobile stations.
Land Mobile Satellite Service:
A mobile-satellite service in which mobile earth stations are located on land.
A radiocommunication service in which the transmissions are intended for direct reception by the general public. This service may include sound transmissions, television transmissions or other types of transmission (CS).
Broadcasting Satellite Service:
A radio-communication service in which signals transmitted or retransmitted by space stations are intended for direct reception by the general public. In the broadcasting-satellite service, the term “direct reception” shall encompass both individual reception and community reception.
A radio-communication service for the purpose of radiodetermination.
Radiodetermination Satellite Service:
A radio-communication service for the purpose of radiodetermination involving the use of one or more space stations. This service may also include feeder links necessary for its own operation.
A radiodetermination service for the purpose of radionavigation.
Meteorological Aids Service:
A radiocommunication service used for meteorological, including hydrological, observations and exploration.
Meteorological Satellite Service:
An earth exploration-satellite service for meteorological purposes.
Standard Frequency and Time Signal Service:
A radiocommunication service for scientific, technical and other purposes, providing the transmission of specified frequencies, time signals, or both, of stated high precision, intended for general reception.
Standard Frequency and Time Signal-Satellite Service:
A radiocommunication service using space stations on earth satellites for the same purposes as those of the standard frequency and time signal service. This service may also include feeder links necessary for its operation.
Space Research Service:
A radiocommunication service in which spacecraft or other objects in space are used for scientific or technological research purposes.
A radiocommunication service for the purpose of self-training, intercommunication and technical investigations carried out by amateurs, that is, by duly authorized persons interested in radio technique solely with a personal aim and without pecuniary interest.
Amateur Satellite Sevice:
A radiocommunication service using space stations on earth satellites for the same purposes as those of the amateur service.
Radio Astoronomy Service:
A service involving the use of radio astronomy.
Any radiocommunication service used permanently or temporarily for the safeguarding of human life and property.
A radiocommunication service, not otherwise defined in this Section, carried on exclusively for specific needs of general utility, and not open to public correspondence.
Acronym for supervisory control and data acquisition, a computer system for gathering and analyzing real time data. SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining and transportation. A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion. SCADA systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or incredibly complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system.
A one-way communications service from a base station to mobile or fixed receivers that provide signaling or information transfer by such means as tone, tone-voice, tactile, optical readout.
