4. Implement Central Wi-Fi Service in Departments

This is a cooperation scheme between ITSC and departmental users, e.g. colleges, faculties and departments. Under the scheme, departmental users may estimate the areas of coverage, number of target users and budget to install wi-fi access in their own areas, e.g. meeting rooms, offices and laboratories. ITSC would then offer professional consultancy, help contact the vendor and provide technical support upon installation.
