Network cabling, Wi-Fi and security for corporate offices
Cablify installs structured cabling, fiber, access point drops, conference room cabling, cameras and access control for corporate offices, from a single floor to a headquarters, in new space or on floors people are still using.

Two Category 6A cables per access point
TIA’s 2023 addendum to its commercial cabling standard, TIA-568.1-E-1, adds a requirement for two Category 6A cables to each wireless access point. TIA’s access point guidelines, TSB-162-B, cover how that cabling is laid out, installed and tested, and the earlier edition recommended a grid of cells up to 60 feet square.
Wi-Fi 7, IEEE 802.11be, was published in July 2025. Its access points ship with multi-gigabit uplinks, and running 10 Gb Ethernet the full 100 meters takes Category 6A.
- Two Category 6A drops to every access point location
- A grid of access point locations planned before ceilings close
- Spare drops at likely future access point spots
- Every run tested and labeled at both ends
Power over Ethernet in bundles
IEEE 802.3bt Type 3 delivers 60 watts at the switch and 51 at the device, and Type 4 delivers 90 watts and 71.3. Access points, cameras, displays and even lights now draw that power through the same cables that carry data, and a tight bundle of powered cables heats up.
The National Electrical Code added Table 725.144 in 2017 to set conductor ampacity for 4-pair cables carrying power, and since the 2020 edition it applies when the power supplied is more than 60 watts. Cable listed as LP, for limited power, is rated for a stated current per conductor.
Bundle size
Smaller bundles and more spread between them for high-power runs.
Cable choice
Category 6A or LP-rated cable where Type 4 devices are planned.
Routing
Bundles kept out of sealed spaces and away from heat sources.
Rooms that need more than a desk drop
Many offices now have fewer assigned desks and more rooms built around screens, cameras and access points.
Conference rooms
Drops for displays, cameras, room panels and table connections, with pathways to the AV rack.
Open office
Zone cabling from the ceiling so desks can move without new runs.
Phone rooms and focus rooms
A drop and an access point within reach of every small room.
Reception and entries
Card readers, door contacts, intercoms and lobby cameras.
IDF and server rooms
Racks, cable management, fiber and labeled patch panels.
Pantries and lounges
Displays, access points and power-ready drops for equipment.
Work on floors people are using
CBRE put U.S. office vacancy at 18.2% in the third quarter of 2026, with 4.9 million square feet of positive absorption. Companies are moving, consolidating and refitting, and much of that work happens on floors that stay open.
We phase work by zone, run cable after hours where the ceiling has to open over desks, and keep port maps current so the help desk is never guessing.
Example
Refitting an occupied floor
- Walk the floor and test what is already there
- Remove abandoned cable from the zones being opened
- Pull new runs after hours, one zone at a time
- Move users to new ports and update the port map the same night

Common questions
How many cables does a Wi-Fi access point need?
TIA-568.1-E-1 adds a requirement for two Category 6A cables to each wireless access point. Two runs give room for multi-gigabit links and power.
Do I need Category 6A for Wi-Fi 7?
Wi-Fi 7 access points use multi-gigabit uplinks, and 10 Gb Ethernet over the full 100 meter channel needs Category 6A.
Does PoE affect how cable is installed?
Yes. Powered cables in tight bundles heat up. The NEC sets ampacity limits for 4-pair cables carrying more than 60 watts, so high-power runs are bundled and routed with that in mind.
Can you work while we are in the office?
Yes. We phase by zone, work after hours where needed and keep port maps current through the move.
