Solutions to radio frequency interference in airports

With the improvement of people's living standards, tourism has become more and more popular, and modern airports handle a huge amount of air traffic. When dealing with hundreds of takeoffs and landings, topological hazards, weather changes, mechanical failures and security threats every day, the most important thing for air traffic control is communication. This is why in a busy airport, when communications (especially RF communications) are compromised, there is no choice but to completely downsize until the problem is resolved, which can cost millions of dollars.

RF has many civilian and military uses, which means that there are many potential sources of interruption (accidental or premeditated) and can cause confusion when an interruption occurs. Since in most cases the reported problems are not measurable, there is a lack of data to classify the interference (signal strength, duration, affected frequency, etc.). The process of identifying and isolating the source can be difficult; not all interference is permanent, so when the surveillance equipment arrives on site, the signal source may have stopped working or switched location or frequency. Various activities may cause RF interference; some may be harmful, some are caused by the legal operation of frequency conflicting electronic products, and some are caused by malfunctions. In order to find and solve problems, RF monitoring equipment operated by qualified engineers must be deployed to determine the exact frequency and direction of interruption. A malfunctioning transceiver on the plane will cause interference and interrupt the normal operation of the control tower for months, but it remains undetected.

Potential solution: continuous monitoring

Some companies have developed equipment for continuous RF monitoring designed to provide wide area coverage and provide a constant flow of information about upcoming and ongoing interference. Although this requires the purchase of expensive equipment, the potential savings in reducing downtime can be substantial. By simply picking up civilian RF jammers, cellular jammers or GPS jammer, such a system can quickly guide operators to the root cause of the interference and save valuable time, thereby greatly limiting the financial impact of these interferences.

As radio waves and traffic lanes become more and more crowded, RF interference has gradually changed from a nasty threat to a terrible threat. The fragility of RF communications means that finding and eliminating any sources of interference is critical to the safe operation of airports. Whether by increasing the deployment speed of RF surveillance vehicles or investing in fixed RF surveillance solutions, airports must make investments to maintain the integrity of their communications.
