This unified control eliminates the hassle of juggling multiple systems, allowing ISPs to simulate various network scenarios with ease.

The setup focuses on creating controlled RF conditions to mimic different signal strengths and interference patterns. For example, ISPs can replicate environments like apartment complexes or office buildings where multiple access points compete for bandwidth. The LANforge platform also allows the creation of diverse client profiles, varying in capabilities, MIMO configurations, and behavior patterns. This ensures the testing process captures a wide range of real-world device scenarios customers might face.

By setting up this controlled environment, ISPs can establish a solid foundation for accurate and automated testing.

Running Automated Test Cases

Candela’s automated testing tools let ISPs run extensive test suites with minimal manual effort. These automated tests ensure consistency by executing preconfigured scenarios, such as TR‑398 and data plane tests, which simulate various client behaviors.

The WiFi data plane test, for instance, examines hundreds of variable combinations, including station types, MIMO configurations, channel bandwidths, traffic patterns, and frame sizes. This testing approach quickly identifies recurring issues or trends that need deeper investigation. Since these tests are automated, ISPs can run them overnight or during off-peak hours, freeing up valuable staff time.

For more dynamic testing, the WiFi Client Reset Test replicates situations where multiple clients connect and disconnect rapidly, exposing potential access point weaknesses. Long-duration stability tests, involving several Wi‑Fi clients, push access points to their limits over extended periods to uncover issues like memory leaks or performance degradation.

The insights from these automated tests become the basis for targeted network improvements.

Reading Test Results

Interpreting test results effectively is key to optimizing network performance. Once the tests are complete, Candela’s platform generates detailed HTML and PDF reports that document key performance metrics.

Throughput analysis shows how well the network handles data delivery under varying conditions, while RF performance metrics – like RSSI, SNR, and PHY rates – shed light on physical layer performance. If throughput drops significantly with increased client loads or specific traffic types, it could signal issues like airtime fairness problems. Similarly, dips in RF metrics may point to interference or poor coverage.

Patterns of packet loss in the results can highlight congestion points or misconfigurations that need immediate attention. The reports also track long-term stability metrics, which can reveal gradual performance declines caused by memory leaks or hardware/firmware limitations.

Additionally, connection stability data from TR‑398 tests provides insights into how well access points manage client associations and roaming. Weak performance in these areas can directly affect the user experience, making them critical targets for optimization.
