As a continuous effort, we have been working to improve the WiFi service on the University campus. In the past few years, we have upgraded the WiFi access points to support 802.11n dual radio WiFi networking standards. To cope with the ever increasing demand for WiFi service, more and more access points have been added to enhance the WiFi coverage and capacity. Moreover, the connecting network switches have also been upgraded to Gigabit models to align with the enhancement in speed of 802.11n WiFi access points.
The WiFi access points are installed at various locations in the campus network, and all WiFi access points are centrally managed by WiFi controllers installed at campus network backbone. The data traffic of the WiFi access points will be switching through the WiFi controllers and in turn passing through campus network backbone switches. As a result, the overall WiFi performance will be affected by the available bandwidth of the network connections between WiFi controllers and campus network backbone switches.
Previously, the network connections between WiFi controllers and campus network backbone switches were Gigabit Ethernet ports, with a maximum throughput of 4Gbps per WiFi controller. In order to further enhance the WiFi network performance, the network connections between WiFi controllers and campus network backbone switches had been upgraded to fibre 10Gigabit Ethernet ports in August 2013, with a maximum throughput of 10Gbps per WiFi controller. After this upgrade, the network throughput of the WiFi controllers has been enhanced to cater for a higher volume of WiFi traffic and more WiFi connections, and to support for future expansion of WiFi coverage.
