Interference testing is a method used to evaluate how different signals or devices affect each other. This is particularly important in fields like telecommunications and electronics, where multiple devices operate in close proximity. By measuring the impact of one signal on another, engineers can identify potential issues and ensure that devices function correctly without unwanted disruptions. During interference testing, various scenarios are simulated to observe how devices respond to interference. This helps in designing systems that can minimize or eliminate interference, ensuring reliable performance. Proper interference testing is crucial for maintaining the quality of services in technologies such as Wi-Fi, cellular networks, and radio communications.
