An office network is one of those things nobody thinks about until it fails, and by then it is usually expensive to fix. Cables have been closed into ceilings without labels, a consumer router is doing the job of a firewall, and the Wi-Fi works in the meeting room only if you sit near the door.
This checklist is what we work through when we plan an office network installation for a business in the UAE. Use it to brief a contractor, to check a quote, or simply to make sure nothing important is missed during a fit-out.
1. Before anything is ordered
- Headcount, now and in two years. Plan for the team you expect, not the team you have. Adding cable later costs far more than adding it during the fit-out.
- Everything that will use the network. Laptops and phones, but also IP phones, printers, CCTV cameras, access control, card terminals, meeting room screens and any smart building devices.
- What the business runs on. Cloud applications, file servers, an accounting system, video calls. This tells you how much bandwidth and how much resilience you need.
- The internet connection. Order the business line early, because the provider's installation can take longer than the fit-out. Decide whether you need a second line or a mobile backup.
- Building rules. Check what the landlord or building management requires for cabling, containment and works permits before the contractor starts.
2. Site survey
- Get the floor plan and mark every desk, meeting room, printer, screen and camera position.
- Choose the comms room or rack location. It needs power, ventilation and ideally its own cooling, because a rack in a closed cupboard gets very hot in a UAE summer.
- Plan the cable routes and containment: ceiling type, floor boxes, risers between floors.
- Survey for Wi-Fi coverage before deciding how many access points to buy. Glass partitions, concrete cores and lift shafts all change how signal travels.
3. Structured cabling
- Use Cat6 or Cat6A for copper runs. Keep each channel within the 100 metre Ethernet limit, and use fibre for longer runs or links between floors.
- Give every desk enough data points, plus spares. Add points for access points in the ceiling, cameras, printers and screens.
- Terminate everything on patch panels in the rack, not loose cables straight into a switch.
- Label both ends of every cable to one numbering scheme, and keep a cable schedule that matches the labels.
- Test every run and keep the results. A cable that fails a test is far easier to fix before the ceiling tiles go back.
4. Switching and power
- Use managed switches so that you can create separate networks, see what is connected and troubleshoot remotely.
- Work out the Power over Ethernet budget. Access points, IP phones and cameras all draw power from the switch, and an underpowered switch causes problems that look like faulty devices.
- Leave spare ports for growth.
- Put the core equipment on a UPS so that a short power cut does not take the office offline.
5. Security and segmentation
- Separate the network into VLANs: staff, guests, voice, cameras and any payment devices. A visitor's laptop should only ever see the internet.
- Use a proper business firewall rather than the internet provider's router.
- Give remote staff access through a VPN, not by opening ports to the internet.
- Change every default password, use named admin accounts, and store credentials somewhere the business controls.
- Agree a schedule for firmware updates on the firewall, switches and access points.
6. Wi-Fi that actually covers the office
- Plan access point positions from the survey, not by guesswork. Several well placed access points beat one powerful one.
- Use WPA2 or WPA3 for staff, and a separate guest network that is isolated from everything else.
- Make sure devices can move between access points without dropping calls.
- Mount access points on the ceiling where they were planned, with cable to each one.
7. Resilience
- Decide what happens when the main internet line goes down: a second line, or automatic failover to mobile data.
- Keep spare patch leads and know where to get a replacement switch quickly.
- Back up the configuration of the firewall and switches so a replacement can be restored in minutes.
8. Documentation and handover
This is the part most often skipped, and the part that saves the most money later. At handover you should receive:
- An IP addressing plan and a VLAN map.
- A port map showing which outlet connects to which switch port.
- An inventory of every device, with model, serial number and location.
- Admin credentials, handed over securely.
- As built drawings showing cable routes and outlet positions.
With that pack, any competent engineer can support the network. Without it, every change starts with a day of detective work.
9. Testing before go-live
- Check every outlet connects at the expected speed.
- Walk the office on a video call to confirm Wi-Fi coverage and roaming.
- Confirm the guest network cannot reach staff devices.
- Pull the main internet line and check the failover works.
