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 multipath 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.
