Satellite Earth Station Frequency Protection
Frequency protection services are provided by Micronet to ensure the ongoing interference-free operation of satellite earth stations. In those bands such as 4GHz and 6GHz where the band is shared between satellite earth stations and terrestrial microwave facilities, the potential for new interference is created with the introduction of any new transmitter. Comparable issues exist at 11GHz for the international portion of the band, and at 18GHz.
The frequency protection service works as follows at Micronet:
- When a client decides to protect a transmit and/or receive facility, Micronet flags the description of the facility in the Micronet facilities database as that of a protection client.
- Each time prior coordination letters are received from other carriers or other coordination companies, the facility described in the letter is analyzed for potential interference conflicts with all of the facilities in the protection database.
- When interference conflicts are established, Micronet generates a coordination objection letter advising the carrier or its representative, of the conflict and asserting the rights of the potentially affected Micronet client. The objection letter is typically supported by propagation calculations. This same information will be sent to the Micronet client.
- Micronet also studies Point-to-Point, Multiple Address Systems (MAS[1]), and Earth Station FCC Applications (New, Renewal and Modifications), to determine if the filings are different from the prior coordinated system parameters.
- If an unresolved interference case is noted on file at the FCC, a letter will be generated by Micronet and sent to the Interfering Coordinator and the Micronet client, so that appropriate action can be taken at the FCC to hold or dismiss the Interfering Application before harm is done to the client’s protected facility
- A monthly report is provided to the Micronet protection client. The report summarizes the number of interference conflicts established, and the number resolved.
