RF Interference Analysis: Methods and Best Practices

RF interference is one of the most common causes of wireless system performance degradation. Systematic interference analysis identifies potential problems early and enables effective mitigation strategies.

Identifying Interference Sources

Interference sources include co-channel and adjacent channel signals, intermodulation products, spurious emissions, and unintentional radiators. A thorough site survey combined with spectrum analysis reveals the actual RF environment your system must operate in.

Predictive Analysis

Before deployment, interference analysis uses propagation modeling, antenna patterns, and transmitter characteristics to predict potential interference scenarios. This proactive approach is far more cost-effective than troubleshooting problems after installation.

Mitigation Strategies

Effective mitigation options include frequency coordination, antenna pattern optimization, filtering, physical separation, and timing-based techniques. The best strategy depends on the specific interference mechanism and operational constraints.

Ongoing Monitoring

RF environments change over time as new systems are deployed and existing ones are modified. Continuous or periodic spectrum monitoring catches emerging interference issues before they impact service quality.
