This thesis explores various Wi-Fi redundancy methods to enhance network resilience in industrial settings. Maintaining uninterrupted data transmission is crucial due to the increasing reliance on wireless technologies for industrial operations. Our research investigates the performance of different redundancy strategies, including Multi-Link Operation (MLO) and Truncated Automatic Repeat Request (TARQ), through practical prototyping and testing on specific hardware configurations. We aim to assess these methods' effectiveness in mitigating packet loss and improving transmission consistency under varying attenuation. The findings are expected to provide valuable insights into the potential of existing redundancy methods to improve Wi-Fi network robustness.

This thesis evaluates two main redundancy methods: MLO and TARQ. In our findings, MLO demonstrated improved packet transmission consistency at lower levels of signal attenuation compared to standard implementations. TARQ, particularly on the 2.4 GHz band, significantly reduced packet loss across a wide range of attenuation levels, thus showing its potential to enhance network reliability.
