“AI-ready cabling” is a phrase with obvious marketing potential and a real meaning underneath it. The marketing version implies some special cable. There isn’t one. Cat6A does not know what a language model is.
The real version is more useful: the pattern of demand on an office network has shifted, and cabling designed against the old pattern will underperform against the new one. Since cabling has a 15-to-20 year service life and gets installed behind ceilings during a narrow window of a fit-out, designing against a pattern that is already changing is an expensive mistake to make quietly.
Here is what actually changed and what it means for a design.
What AI adoption does to an office network
Most AI usage in an office is cloud-based — a browser tab talking to a remote service. That is not, in itself, heavy on the local network.
What matters is what it displaces and what it accompanies.
Traffic patterns became sustained rather than bursty. Traditional office traffic was spiky: load a page, idle, send an email, idle. AI-assisted workflows produce continuous request-response cycles throughout the working day. Coding assistants, document tools, transcription running in the background, meeting summarisation. Individually modest; collectively a rising baseline that never really drops.
Uplink demand rose. Office networks were historically asymmetric in the download direction. Sending context, documents, code, images and audio to remote services has pushed sustained upstream traffic up materially — and upstream is usually the direction with less headroom.
Video and audio processing moved into every meeting. Real-time transcription, translation and summarisation mean meeting room traffic is now sustained bidirectional streams rather than a call that occasionally happens.
Some workloads came back on-premise. Organisations handling sensitive data — legal, medical, financial — are increasingly running local inference on GPU hardware rather than sending data out. That server sits in your comms room and needs to be fed at multi-gigabit speeds.
None of this individually breaks a well-built network. The relevant point is directional: the assumption that a 1Gbps edge with modest uplink is comfortably over-provisioned is no longer safe over a 15-year cabling lifespan.
The bigger driver: everything is on the network now
Honestly, AI is not even the main pressure on cabling design. Device convergence is.
The network in a modern fit-out carries: workstations, Wi-Fi access points, IP cameras, access control readers, IP intercoms, IP speakers and paging, digital signage, room booking panels, occupancy and environmental sensors, smart lighting controllers, HVAC controls, and increasingly the AV in every meeting room.
Most of these are powered over the same cable. That is the load nobody sized for in 2015.
Two constraints that shape everything: PoE and Wi-Fi 7
PoE heat. As device count and power draw rise, PoE++ (802.3bt) delivers substantially more power per port, and that power becomes heat inside cable bundles. Heat raises insertion loss, which degrades performance and, in dense bundles in warm ceiling voids, can push cable outside its rated operating conditions. This is a real design consideration in Dubai, where ceiling void temperatures are not gentle. Cat6A handles these thermal loads better than Cat6 — this is one of its underrated advantages and arguably now a stronger argument than the 10G distance point.
Wi-Fi 7 backhaul. This is the constraint that most directly dates a cabling design. Wi-Fi 6E and Wi-Fi 7 access points can saturate a 1Gbps wired backhaul. An AP capable of multi-gigabit throughput connected by a 1Gbps drop is bottlenecked at the cable, and the only fix is pulling new cable above a finished ceiling in an occupied office.
Given that most users reach the network wirelessly, and that AP density is rising rather than falling, AP drops are where under-specification hurts most and costs most to remedy. If you take one thing from this article: do not economise on access point cabling.
What to specify
Cat6A as the horizontal default. 10GBASE-T to the full 100 metres under ANSI/TIA-568, better PoE++ thermal behaviour, and a service life that matches the building rather than the current switch generation. Because labour dominates installed cost, the category upgrade is a small proportion of project spend.
Two Cat6A drops to every access point position. One for the AP, one spare. The spare costs a fraction of what it will cost to add later. Multi-gig APs increasingly support link aggregation, and the spare covers both that and a future AP relocation.
Higher AP density than the coverage calculation suggests. Coverage-based planning is obsolete; modern design is capacity-based. Cable more AP positions than you currently intend to populate — the drop is cheap, the retrofit is not.
Fibre backbone, sized generously. Between comms rooms and between floors. Specify more strands than the current requirement. Dark fibre in a riser is one of the cheapest future options available at fit-out stage, and one of the most expensive to add afterwards.
Comms rooms with genuine power and cooling headroom. This is where fit-outs are most consistently underdesigned. High-density PoE switches draw serious power and reject serious heat. If there is any prospect of on-premises GPU hardware, that changes the room’s requirements substantially. Specify power, cooling and physical rack space with real margin — a comms room is very difficult to enlarge later.
Consolidation points in open-plan areas. Office layouts change constantly. A consolidation point lets you re-cable a zone without pulling back to the comms room every time the furniture plan changes.
Certification testing and full as-built documentation. Every link certified, results handed over, TIA-606 labelling. This is what makes the infrastructure diagnosable and extendable for the next fifteen years. It is also the item most often stripped out of a quote to make the number look better.
Where fibre belongs, and where it doesn’t
Fibre is correct for backbone, for runs beyond 100 metres, for inter-building links, and for electrically noisy environments.
Fibre to the desk remains wrong for a normal office, and the reason is PoE. Fibre carries no power. Since a growing share of your endpoints are powered over the cable, replacing horizontal copper with fibre creates a power problem at every device position. Add per-port transceiver costs at both ends of every link and the economics get worse still.
Fibre backbone, Cat6A horizontal remains the right architecture, and the AI-era changes reinforce that rather than challenge it.
The design questions worth arguing about
When reviewing a cabling design for a Dubai fit-out, these are the points where pushing back pays:
- How many AP positions are cabled, versus how many are being populated on day one?
- Are AP drops Cat6A, and is there a second drop at each position?
- How many fibre strands in the riser, and what is the spare capacity?
- What is the power and cooling headroom in each comms room, in percentage terms?
- Is PoE budget calculated against projected device count, including cameras, readers, signage and sensors — or just today’s?
- Are bundle sizes and pathway fill accounting for PoE++ thermal derating?
- Is certification testing included as a deliverable, with documentation?
- Where are the consolidation points, and do they align with likely layout changes?
A designer who has thought about the next decade will have answers. One who has priced a conventional office will not.
The economics that make this easy
The reason to resolve all of this during fit-out is simple: cabling installed while ceilings are open and walls are unclosed costs a fraction of the same cabling installed after handover. Labour is 70–80% of installed cost, and the labour difference between open-ceiling and occupied-office work is enormous.
This produces a straightforward rule: at fit-out stage, over-provision. Afterwards, you will be paying premium rates to fix under-provisioning.
Spare drops, spare fibre strands, spare comms room capacity, spare AP positions. Each is cheap now and expensive later. This is one of the few areas in a fit-out where deliberately buying more than you need is the financially disciplined choice.
Summary
There is no AI cable. There is a shift in what office networks carry: sustained rather than bursty traffic, more upstream, far more powered devices, and access points that can saturate gigabit backhaul.
Design against that with Cat6A horizontal, generous AP cabling, a fibre backbone with spare strands, and comms rooms with real headroom. Do it while the ceilings are open, because that window does not reopen.
