3. Broadband technology: The technology to be used shall be chosen according to location, institutional business requirements, and offices set up. Wireless local area networks are advised for convenient and modernized work spaces.
4. Physical network diagram: The design of the physical network diagram will consider the number of users based on the institutional structure, the interior design/aesthetic of the building and sitting arrangement (i.e. whether all users sit on the same floor or on different floors) and shall also consider whether the infrastructure of the building is shared or not.
5. Logical network diagram: The design of the logical network diagram shall consider existing systems, services, and applications according to the institutional business processes. The design      should also provide the capability for scaling up and growth.
6. Network Security: All Government institutions shall comply with the current cyber security directives for network and information systems issued by a competent authority.
