    Buildup of WiFi Network

    Information Note to Schools
    Introduction
    For your school’s preparation of enhancing / topping up the IT infrastructure, you may make reference to this information note in considering the standard provision and add-on services required by your school.
    Standard Provision
    From schools’ experience in the Support Scheme for e-Learning in Schools and also WiFi 900 Batches 1 & 2, the following provision is considered sufficient for students to access the e-learning resources and conduct common e-learning activities. It is outlined here for schools’ reference in figuring out the expected service to be delivered by the WiFi network.


    • WiFi Connectivity–use IEEE 802.11 a/b/g/n/ac or above network in a standard classroom. The minimum number of classrooms to be covered should be at least equal to the number of approved classes for the 2017/18 school year.




    • Number of Concurrent Connection–commensurate with the maximum number of students, say 40, in a class with at least 1 Mbps upload / download bandwidth per user connection.



    • Number of classrooms using WiFi concurrently.




    • Authentication Method–use 802.1x standard based authentication and Hong Kong Education City single sign-on services




    • Session Control – Hong Kong Education City authentication service can support one device or multiple devices to connect based on user group (student, teachers).





    • Existing Network Facilities – not rely on any existing network facilities and cabling of the School, nor interfere with the existing WiFi network of the School. The Wi-Fi network shall be physically separated from the school network




    • Broadband Network – use separate broadband for the WiFi service. State otherwise if the existing broadband can be utilized for the service.




    • Managed Service–operate the WiFi network using managed service model, provide end-to-end service with single point of contact including configuration, provisioning of service, proactive monitoring, maintenance and regular reporting.




    • Service Level Agreement–ensure at least 99.7% availability of the WiFi service, support four-hour response time and four-hour service recovery with active monitoring, helpdesk support with support hours from Mon to Sat 8:00 am to 6:00 pm, and provide monthly monitoring reports for School.



    • Contract End Arrangement– All provisions of trunks, conduits, cables, LAN ports and power points shall be considered as fixture of the School and shall become the property of the School. The Contractor shall remove or keep those provisions according to the instruction of the School. Contractor can remove the network equipment such as switch, routers, and access points.


    Add-on Service
    Some schools may have other considerations in the use of WiFi network in their campus. Such add-on service may incur more development time and extra expenditure from schools. The variation could be


    • WiFi Coverage– include special rooms and open areas




    • Broadband Service–provide broadband service with at least 100Mbps Internet connection at school and allowing upgrade to 1Gbps




    • Authentication Method –user account system being used by School




    • Session Control –Other requirements.





    • MAC Address Monitoring – The lists of filtering and filtered MAC addresses are to be managed and monitored by the Contractor or the School.




    • Internet Content Filtering Service–specific request on content filtering



    • Integration of networks – system integration with existing network with secure design.




    • Internet addresses subscription & configuration – for Internet access to school internal resources.




    • Monitoring of WiFi network–specific request on monitoring of WiFi network by School




    • Redundancy– increase the availability of the WiFi service




    • Supporting hours–extended support hours and/or reduced time for recovery




    • Contract End Arrangement–Other requirements.


    Wi-Fi.HK Service
    Schools may consider the provision of free Wi-Fi services in some common areas such as reception area and student hall to school visitors e.g. parents by allowing the service provider (SP) to set up free Wi-Fi service using the school WiFi network infrastructure, under the Wi-Fi.HK brand1, with a SSID “Wi-Fi.HK via <name of SP>”. The Wi-Fi.HK service is a public Wi-Fi initiative not related to the schools or EDB and will not incur extra expenditure from schools. The respective SP will answer public queries about the service and register with OFCA those hotspots that are going to provide public Wi-Fi service under Wi-Fi.HK.
    It is outlined here for schools’ reference and consideration on the related service requirements.

    • Authentication- landing page with Wi-Fi.HK logo, terms and conditions and disclaimers but no registration/login is required for use of Wi-Fi.HK; users can use the free Wi-Fi service after accepting the terms and conditions in the landing page

    • Content filtering- can also apply to Wi-Fi.HK though it is not mandatory

    • Integration - the network for supporting Wi-Fi.HK shall be isolated from the School’s network without direct access; connections via Wi-Fi.HK shall have access to the Internet only

    • Helpdesk - service provider will provide hotline service and contact email for public enquiry of its service

    • Digital server certificate – preferably use digital server certificate issued by recognized certificate authority on the landing page so that users can easily discern the legitimacy of the Wi-Fi services
