Technical report explaining why conventional internet speed tests are insufficient for evaluating the real performance and reliability of Wi-Fi networks in practical environments.
Internet speed tests are widely used as a quick method for evaluating wireless network performance. However, throughput measurements alone do not reflect the actual quality of a Wi-Fi network.
This report explains why conventional speed tests fail to capture critical factors influencing real-world wireless performance, including signal quality, interference, roaming behaviour, retransmissions and infrastructure limitations.
The analysis highlights the distinction between Internet bandwidth and Wi-Fi network performance and outlines the need for structured methodologies capable of evaluating wireless networks under realistic operating conditions.
