RF Interference Tracing

And Radiation Analysis as a Service

This webpage is dedicated to NWNS Interference Tracing & Radiation Analysis Services. We are in business but its promoting webpage is still under construction. If you however can’t wait for more information please send us an email with your questions or requests to request@nwns.org

Your critical link suffers from annoying, often unpredictable intermittent degradation? This could be interference

Most interference is unintentional, which can it make extremely difficult to overcome. Unless the problem is very simple, the only really productive approach is an orderly and systematic one that first finds the cause of the specific problem, then applies appropriate corrective action.

Interference is annoying, frustrating and not always understood

The more urban and/or population dense the area, the higher the likelihood of (unpredictable) interference.

Interference problems can be difficult to track down, and even more difficult to solve. And whatever we do to fix the issue, we will not eliminate the interfering signal, we’re only trying to mitigate its disturbing influence.

A clean, interference free spectrum today is not a guarantee for tomorrow’s situation.

The risk of harmful interference from any kind of radiator can usually be reduced through the use of various interference prevention measures, and the risk of sustained interference generally can be eliminated through various interference mitigation techniques. Click here to learn more.

NWNS’s Approach

NWNS performs a professional and very thorough interference inspection. Other than trial and error, this is a highly technical operation, and only a few of our field engineers are capable of performing it.

Why? Because it requires a lot of theoretical knowledge, practical experience, systematic analysing, lots of patience, and beyond standard (rather expensive) measurement equipment such as probes, special antennas and a spectrum analyser supporting the required functionality.

There’s simply no trick (one can learn without understanding what you’re doing) that can possibly bypass the necessary steps in the process.

If done properly, such an exercise can take more than a day because you want to observe the behaviour of the frequency spectrum under test for at least 24h. Sometimes even longer.

The objective of this more scientific approach is to understand how disturbing signals interfere with our wanted signals, when, where and how it enters the system and how we can mitigate the situation.

Specific example: If interference is caused by reflection and we understand the basic facts, moving the satellite dish antenna 1 m either way can already give good results and there’s no further need for iffy constructions. Also calculated shielding in specific places around the antenna or feedhorn can do the magic (see picture)

Conclusion: before thinking about any solution, we first want to have the problem clearly defined. After-all, understanding our problem is 50% of the solution.

Unfortunately, positive results can never be guaranteed.
