Issue 44 - June 2005
CityU has been offering the Wireless LAN (WLAN) service since 1997. The population of registered WLAN clients has increased more than ten folds from less than 200 at the beginning to more than 3000 clients now.
WLAN technology is changing rapidly and new standards are emerging in the market. Products with higher speed and rigid security are becoming affordable. As our WLAN is already 7 years old, it is about time to replace the old WLAN system with a new one in order to provide more bandwidth and better performance in a more secure way for the benefit of our users.
The project was started in June 2005 and expected to take several months to complete. The intelligent wireless LAN switching solution from Aruba has been employed to replace the old Vernier Authentication Server and low speed Orinoco Access Points (APs). Initially 400 new APs will be installed to provide a wider coverage than the previous 250 APs by extending to areas such as laboratories within departments.
Our first phase of the implementation will include all existing areas and we expect to complete the set up of the new WLAN and replacement of APs before Semester A of 2005/06. Existing authentication methods (Web and VPN logon) that we are familiar with are still available in the new system. Users may notice that a new login page is displayed when their PCs are attached to the new system.
As the migration period will take quite long, we shall try our best to keep the transition as smooth as possible to avoid any service interruption. If you encounter any difficulties in using the WLAN service during the upgrade period, please contact our CSC Help Desk or write to firstname.lastname@example.org for our action.
Advantages of the New System
The WLAN service in CityU aims to provide a convenient and secure means to our staff and students for mobile computing. The Computing Services Centre will continue to keep enhancing the service by accommodating the latest technology and provide our users with the best solution.
