Position paper examining why increasing Internet bandwidth often fails to resolve underlying WiFi performance issues and why objective assessment is essential for identifying the true source of connectivity problems.
Many organisations assume that poor WiFi performance can be resolved simply by increasing Internet bandwidth or changing Internet providers. While Internet capacity remains an important component of network performance, it is often not the root cause of user complaints.
This position paper examines common wireless and infrastructure-related factors that can degrade user experience independently of ISP bandwidth, including signal quality, interference, airtime utilisation, client behaviour, infrastructure limitations and network design issues.
The paper highlights the distinction between Internet capacity and WiFi network performance and advocates a measurement-based approach centred on the principle of Observed Network Reality.
