Most office networks are not built in one go. They grow: a switch added here, an access point plugged in there, a few extra cables run when a new team joins. After a few years the result is a network that mostly works — until video calls freeze or the Wi-Fi drops in the meeting room. A planned upgrade is far cheaper and less disruptive than fixing a network that has quietly outgrown itself. This checklist covers the three layers that matter most: switches, Wi-Fi and cabling.
First, find out what you actually have
Before buying anything, audit the current network. List every switch, access point and router, note their age and model, and map which wall outlets and devices connect to which switch port. Check whether your internet circuit is the bottleneck — run a speed test at the router, not over Wi-Fi — and ask staff where the problems happen. Slow Wi-Fi in one corner and slow file access everywhere are different problems — an audit stops you spending on the wrong one.
Switches: the backbone of the upgrade
The switch is where every wired device meets, so it sets the ceiling for the whole office. Start with capacity: count the devices that need a wired connection today, then add headroom of around a quarter for growth. If you are daisy-chaining small desktop switches, you have already outgrown the current setup.
- Speed: gigabit ports are the baseline for desktops, printers and access points. If your team moves large files — design work, video, CAD — consider multi-gigabit uplinks between switches and to the server or NAS.
- PoE: if your phones, cameras or access points run on Power over Ethernet, the switch must supply enough PoE power for all of them at once. Check the total PoE budget, not just the port count.
- Managed vs unmanaged: a managed switch lets you segment the network with VLANs — keeping guest Wi-Fi, CCTV and office traffic apart — and monitor port errors. Beyond a very small office, managed is worth it.
Wi-Fi: coverage, capacity and placement
Wi-Fi complaints are usually about capacity or placement, not the broadband line. One access point in a central corridor rarely covers a whole floor well, and walls, glass partitions and neighbouring networks all eat into the signal. Plan access points around a survey, not around where the old ones happened to be.
- Survey before you buy: a walk-through with a Wi-Fi analyser app shows dead spots and channel congestion.
- Match access points to density: a meeting room with twenty laptops on a video call needs far more capacity than a corridor.
- Separate the traffic: staff, guests and IoT devices should sit on separate networks. Guest Wi-Fi in particular should never share the same network as your business systems.
- Check the backhaul: an access point is only as fast as the cable feeding it. If it is plugged into an old 100 Mbps port, the Wi-Fi will never go faster than that, whatever the access point promises.
Cabling: the part nobody wants to redo
Cabling is the least glamorous part of a network upgrade and the most expensive to fix later, because it lives inside walls and ceilings.
- Run more than you need: pulling two cables to each outlet costs little extra while the ceiling is open, and it saves a return visit when a desk gains a second device.
- Label everything: every cable should be labelled at both ends, and the patch panel should match the wall outlets. The next engineer — or your own team in a hurry — will thank you.
- Keep it tidy and tested: a neat patch panel is not cosmetic; tangled, unlabelled cabling is how faults take hours instead of minutes to find. Every run should be tested, not just plugged in to see if the light comes on.
- Plan the routes: keep data cables away from power cables where possible, and document the routes so a future fit-out does not cut through them.
Plan the cutover like a project, not a purchase
Order of work matters. Start with the audit, then the design: a simple diagram showing switches, access points, cable runs and VLANs. Agree on a maintenance window — evenings or weekends — and keep the old equipment running until the new network is tested. A phased cutover, one area at a time, lets staff keep working while you prove each part. Finally, document the finished network: IP addresses, switch logins, VLANs and Wi-Fi passwords. Without documentation, the next fault starts from zero.
A note for growing UAE businesses
Dubai offices often grow in stages — a team expands, a floor is added, a warehouse or second site comes online — and each stage adds devices the original network was never sized for. If your headcount has grown by a third or more since the network was installed, or you have added CCTV, access control or a phone system on the same switches, an audit is overdue. And remember that certain Dubai premises may have SIRA requirements — confirm applicability for your property type before finalising any system that includes CCTV or access control.
