Interference Hunting
Interference hunting requires the ability to spot, find and fix a known interferer which is not always an easy task. Not only having the right tools, but the ability to properly identify the issue is key to interference hunting. As strange as it may sound, the first step to solving an interference issue is actually determining that there really is interference. Sometimes there are other issues at play that cause a communications system to work less than optimally but don’t actually involve an outside signal
What is Interference?
Interference is any unwanted signal that makes a radio receiver’s job harder such as illegal transmissions, unlocked and drifting transmissions, noise from leaky cable TV feeds, unsuppressed EMI from power tools or microwave ovens, local high power radios and even multi-path from nearby buildings and hills. Interference from both illegal and unintentional signals is a significant problem for mobile service providers, security services and government regulators. Interference will degrade network performance, causing critical communications to be interrupted.
Types of Interferers Found
- Illegal transmissions
- Unlocked or drifting radios
- Low power
- Narrowband, wideband
- Damaged or leaking RF cables
- Modulated
- Pulsed signals (similar to radar)
- Signals hidden in LTE uplink channels
- “Pirate” TV/radio stations and BTS cellular equipment operating illegally
