Carrier ID, an industry-wide initiative to reduce satellite interference
CID is the first worldwide standard enabling operators and users to quickly identify interfering carriers and respond to such events, improve Quality of Service and reduce operating costs, and lower the number of interference events.
As the satellite communications market has grown so has the number of antennas accessing satellites and with this, the risk of increased involuntary and voluntary interference. In the vast majority of cases interference is caused by failed equipment or incorrectly configured transmit equipment. The ensuing disruption has far-reaching consequences and the detection, analysis and management of interference are time-consuming and costly.
CID technology was developed by the DVB Group and supported by the World Broadcasting Unions-International Satellite Operations Group (WBU-ISOG), the Global VSAT Forum (GVF) and the satellite Interference Reduction Group (sIRG).
HOW DOES IT WORK?
Carrier ID (CID) adds a “signature” to a satellite uplink, allowing satellite operators to identify the source of an interfering carrier. Existing modulators create two carriers, the primary payload carrier and a low-power CID signal which uses spread spectrum technology. CID comprises both mandatory and optional data fields, which are provided either by the equipment manufacturer, or the user. Only satellite operators will have access to all CID information. They have the ultimate responsibility of maintaining a global and secured CID database in cooperation with their customers and constantly monitoring their satellites for interference events.
