Office Network Cabling Guide: Cat6 vs Cat6a and Planning a Clean Setup

Moving into a new office, renovating or finally fixing a tangle of cables under the desks? The network cabling you put in now will carry your internet, phones, Wi-Fi access points, printers and cameras for the next ten years or more. Getting it right the first time is far cheaper than opening walls later. This guide explains the choices in plain language, including Cat6 versus Cat6a, and what a clean installation should look like. For hands-on help, see our structured cabling service.

Why structured cabling still matters

Even in a world of Wi-Fi, a wired network is the backbone. Wi-Fi access points need cables, desktop computers and phones are more reliable when wired, and cameras and card machines work best on a cable. A planned, structured system means every cable runs back to one place, is labelled at both ends and can be traced in minutes instead of hours.

Cat6 vs Cat6a in plain language

Both are standard network cables. Cat6 comfortably handles the speeds most small offices use today and can carry higher speeds over shorter distances. Cat6a is thicker, better shielded against interference and supports higher speeds over the full length of a typical run. It costs more and takes more space in walls and trays.

• Choose Cat6 for a typical small office with normal desk and printer connections and moderate distances.
• Consider Cat6a for Wi-Fi access point drops, longer runs, environments with electrical interference, or if you want headroom for faster equipment later.
• Avoid mixing standards in the same job without a reason. It complicates testing and support.

Plan the drops before the walls close

Count more than the desks. A good plan includes:

• Two connections per desk, so a phone and computer or a docking station can both be wired.
• Ceiling or high-wall drops for each Wi-Fi access point, placed from a coverage plan.
• Drops for printers, card machines, TVs and meeting room displays.
• Camera and door access locations if you use them.
• A few spare drops in areas likely to change, such as open-plan spaces.

The network closet

All cables should end at a patch panel in a dedicated cabinet or closet with power, ventilation and room to work. From there, short patch cables connect to the switches and router. A clean closet with labelled patch panels makes moves and fixes quick, and keeps equipment from overheating. If the closet is a forgotten corner of a storage room, it is often the hidden cause of random outages.

Labelling, testing and documentation

Every cable should be labelled at both ends with a matching number, tested with a cable certifier or tester, and recorded on a simple plan of the office. This documentation is what lets any technician find and fix a problem quickly years later. If your installer does not provide test results and a map, ask for them.

Common cabling mistakes we fix

• Cables run loose across ceilings or stapled through walls, which damages them.
• Network cables run alongside electrical cables for long distances, causing interference.
• No labels, so nobody knows which port goes where.
• Too few drops, leading to small switches hidden under desks.
• Outdoor or warehouse runs using indoor cable that degrades.

Building in Surrey and the Lower Mainland

Commercial buildings often have rules about after-hours work, fire stopping and ceiling access, and some require approved contractors. We coordinate with property managers and contractors so cabling is done right and on schedule. If you are planning a move, read our new office IT planning guide and our overview of what an office network actually needs. We also provide low-voltage cabling and full network design.

Frequently asked questions

Is Cat6 good enough for a small office?

For most small offices, yes. Cat6 handles the speeds typical businesses use today. Cat6a is worth it for Wi-Fi access point runs, long distances or if you expect faster equipment soon.

How many network points does each desk need?

We usually recommend two per desk, so a computer and a phone or docking station can both be wired, plus extra drops for printers, access points and shared areas.

Can you add cabling to an office that is already built?

Yes. Retrofitting is common. We route cables through ceilings, walls and raceways as neatly as the building allows, and coordinate with the landlord when needed.

Do you provide test results and documentation?

Yes. Every cable is labelled, tested and recorded, and you receive the documentation so future changes and repairs are quick.
