Huawei believes user experience is the most important criteria for determining
Wi Fi network quality.
Generally, network O&M personnel extract network Key Performance Indicators
(KPIs) based on network devices. They then determine the net work quality and
health status of the entire network based on the KPIs. As shown in the following
figure, the access success rate is an important KPI for measuring Wi Fi network
quality. As the number of network access users increases, the access success r ate
decreases. When the access success rate falls below 95%, the network experience is
considered poor.
It is true that the KPI information obtained from network devices or the network
management system serv er may indicate user experience to a certain degree.
However, the KPI information cannot accurately reflect network quality and user
experience. As shown in the following figure, when the number of users accessing
the Wi Fi network increases but has not exceeded the specified threshold and
the access success rate remains above 95%, it is regarded as a good user experience
based on KPI information, specifically, access success rate. However, the actual
network access rate of users falls below 1 Mbps, whi ch indicates a negative user
experience. Therefore, only Key Quality Indicators (KQIs) oriented to users can reflect
the actual user experience.
