Why Speed Tests Do Not Measure Real Wi-Fi Quality

Internet speed tests are commonly used to evaluate wireless network performance. 
However, throughput measurements alone do not reflect the real quality of a Wi-Fi network.

This technical report explains why conventional speed tests fail to capture critical  factors that influence real-world wireless performance, including signal quality,  interference, roaming behaviour, retransmissions, and infrastructure constraints.

The report provides a conceptual analysis of the limitations of speed testing  in Wi-Fi environments and highlights the need for structured methodologies 
for evaluating wireless network quality.
