City University of Hong Kong has full Wi-Fi coverage in the entire campus, powered by over 2,800 Access Points (APs).  These APs are all Wi-Fi 5 (802.11ac Wave2) compatible.  Subsequent to a recent Internet bandwidth upgrade, the individual bandwidth control is unleashed.  In other words, users using Wi-Fi 5 compliance devices on campus can now enjoy much faster campus network and Internet connection when they are connected with CityU’s Wi-Fi service.  For a modern notebook computer equipped with two spatial streams (2 + 2), an average of 300 Mbps upload / download speed can be reached:

Moving Foward

Wi-Fi 6, also known as 802.11ax, is the latest generation of the Wi-Fi standard.  This new standard has many new features and improvements over the Wi-Fi 5.  The Computing Services Centre (CSC) has installed a few Wi-Fi 6 access points for evaluation and will use it for new deployment, particularly in crowded areas such as Lecture Theatres and classrooms.  Table below summarized the features of Wi-Fi 6 and its improvements over Wi-Fi 5.

Outdoor Wi-Fi Coverage

In addition to the performance enhancements, the CSC will be installing outdoor APs to improve and strengthen Wi-Fi coverage in outdoor areas, including:

The CSC dedicates to improve the University’s Wi-Fi service by accommodating the latest technology and, as always, to improve campus experience.  If you experienced any Wi-Fi connectivity issues on campus, you are most welcome to inform us the time and location via csc.servicedesk@cityu.edu.hk for our investigation and improvement actions.
