Cat6 vs Cat6a — which should I install?

Install Cat6 for standard office drops under 100 meters where 1 Gbps is the working requirement. Install Cat6a where you need 10 Gbps at full distance, are powering high-draw PoE devices such as Wi-Fi 6E/7 access points or PTZ cameras, or want the cabling to outlive two equipment refresh cycles.

Cat6 vs Cat6a: Which Should You Install?

The real difference

Both support 10 Gbps, but Cat6 only does it to about 55 meters and only in favorable conditions. Cat6a is specified for 10 Gbps to the full 100 meters and has tighter alien-crosstalk control. Cat6a is also thicker, less flexible, and needs more pathway space — that is where the extra cost lives.

Where Cat6a earns its money

Access point drops, camera drops delivering PoE++ power, conference room AV-over-IP, and any riser or backbone copper. Heat dissipation matters here: higher-wattage PoE runs warmer, and Cat6a handles it better in bundled trays.

Wi-Fi 6E / Wi-Fi 7 access points
PoE++ (60W–90W) devices: PTZ cameras, displays, LED lighting
AV-over-IP and high-density conference rooms
Any drop you do not want to re-pull within 10 years

The honest cost view

Cat6a typically adds roughly 20–40% to material and some labor per drop. On a full building that is real money. A common, defensible approach is Cat6 for standard workstation drops and Cat6a for AP, camera and AV drops — you spend the upgrade where it changes performance.
