Which option describes a method to mitigate wireless impairment assessments?

• A. Increase transmit power.
• B. Implement frequency hopping or spread spectrum techniques.
• C. Disable encryption.
• D. Use a larger antenna.

Answer: (B)

Mitigating wireless impairment assessments relies on boosting the robustness of the radio link against interference and disruptive conditions. Frequency hopping or spread spectrum techniques achieve this by spreading the signal across a wider bandwidth or by rapidly changing frequencies. This means that localized or narrowband interference is less likely to affect the entire transmission, improving reliability even when the environment is noisy or congested. The broader, more resilient behavior is precisely what impairment assessments aim to test and demonstrate.

Increasing transmit power might help reach a clearer signal, but it’s often limited by regulatory rules and can create more interference to others, without addressing the interference pattern itself. Disabling encryption doesn’t relate to impedance or reliability of the wireless link. Using a larger antenna can improve reception or increase range, yet it doesn’t inherently reduce the impact of interference in the same targeted way as spread spectrum techniques.
