How to design an office network

A small or medium office doesn't need a complicated network, but it does need a well-thought-out one. These are the essentials.

1. The rack

A technical cabinet housing the fibre termination, firewall, switches, patch panel and, if any, the NAS or server. Tidy, labelled and ventilated.

2. Structured cabling

Network outlets (Cat 6 or 6A) at every desk, in meeting rooms and for printers and screens. Cable is more reliable than WiFi for fixed workstations.

3. Ceiling WiFi

Professional ceiling-mounted access points powered by PoE, with roaming between areas. Meeting rooms and busy areas need extra capacity.

4. Separate networks

  • Staff: access to internal resources.
  • Guests: internet only, isolated.
  • IP telephony: prioritised.
  • Cameras and access control: closed.
  • Printers and devices: controlled.

5. Security

A managed firewall, strong WiFi passwords, regular updates and secure remote access (VPN) for remote working.

6. Continuity

A UPS in the rack and, if the business requires it, an automatic 4G/5G backup connection.

7. Documentation

Network diagram, labelled outlets and access to the configuration, so your IT provider can work without surprises.

Before moving into new offices or during a refurbishment. If you're already in, it can be done in phases.
