Interference Protection Services

Our comprehensive interference analysis protects your licensed systems from costly service interruptions which can lead to severe degradation of your system reliability. As your protection agent, Comsearch receives all prior coordination notices detailing the technical parameters of any new or modified microwave path or earth station.

Our highly trained analysts use Comsearch's proprietary software tools and our database of protected systems to quickly perform interference analyses. We understand that timing is critical and we immediately report potential conflicts to the new entrant before they can submit an FCC license application. Our analysts follow all conflicts through to resolution, which often involves multiple rounds of discussions and analysis of any proposed interference mitigation attempts (e.g. terrain/building blockage or modifications to their proposal).

We provide you with monthly reports that summarize the new activity, such as the number of PCNs analyzed and number of cases reported, to keep you up-to-date and close to the process.

We know how important it is to have your system data readily available, that's why Comsearch's Frequency Protection Service comes with unlimited web access to your detailed microwave, earth station, and MAS data stored in our proprietary database.
