The mutual influence of Bluetooth Low Energy (BLE) and Wi-Fi 5 technologies in the 2.4 GHz band was investigated, along with an assessment of MU-MIMO technology effectiveness under such interaction. Experimental measurements of key network performance indicators, such as TCP throughput and connection stability, were conducted for various wireless channel configurations. It was established that BLE activity predominantly negatively affects Wi-Fi parameters. The dependency of interference levels on Wi-Fi channel selection and channel width was analyzed. It was shown that MU-MIMO technology, under single-client testing conditions, did not demonstrate significant improvements in performance or interference resilience. It was found that test environment factors can significantly limit baseline network performance.
