Carrier ID

With satellite interference becoming an increasing problem, Carrier Identification (CID) is an important part of the solution to mitigate carrier interference. CID is a signal embedded into a video or data transmission path. It allows satellite operators and end users to identify the source of an interfering carrier. The transition to CID has started from 1 January 2015 (WBU-ISOG Resolutions).

How it works

1. An Identifier Is Injected into the Carrier by the Modulator
The identifier contains mandatory information such as a 64-bit MAC address and a vendor serial number in combination with optional user configurable data such as GPS coordinates, the carrier name and user contact coordinates. This information is injected into the carrier by the modulator at the uplink site.

How it works

2. The Carrier ID Is Transported over Satellite Below the Noise Floor
In order to lower the impact on the throughput over the satellite, the carrier ID information is spread below the noise floor of the carrier. The image depicts an instance of interference between 2 carriers and the location of the carrier ID info.

How Carrier ID works

3. The ID Is Read from the Carrier by Special Measurement Receivers
At the satellite operator facilities special measurement receivers are installed. At any occurrence of interference these receivers can read out the contact information from the carrier and quickly point out the source of interference. Resolving the interference issue is in most cases only a phone call away.
