[Glossary](https://telxpress.com/glossary/) / Network # Cat6 vs Cat6A **Cat6 vs Cat6A** is the choice between two grades of twisted-pair copper cabling; Category 6A supports higher-speed Ethernet over the full standard distance and resists interference better, at higher cost and a thicker cable. - Network - Updated October 11, 2026 - Written by the Telxpress advisory team 01 In depth ## What it is, why it matters and *what to ask a vendor* Both categories are defined in the ANSI/TIA-568 cabling standards. Category 6 is specified to a lower frequency and handles the fastest Ethernet speeds only over shorter runs; Category 6A is specified to a higher frequency, supports those speeds over the full horizontal distance the standard allows, and is built to reduce crosstalk between neighboring cables. It is thicker, needs more pathway space and costs more to install. For a growing business the decision is about the life of the building fit-out, not today's laptops. Wi-Fi access points for the newest generations, meeting-room systems, cameras and anything powered over Ethernet benefit from the extra headroom, and the labor to pull cable is the same either way. Many designs use Cat6A for access points and rooms and Cat6 elsewhere. Ask a cabling contractor what speed and power each outlet will need to support, whether the pathways and panels have room for the larger cable, how the links will be certified, and what the price difference is across the whole project rather than per foot. Ask them to show where Cat6A pays for itself and where it does not. 02 Related terms ## Terms that usually come up *alongside it* - Network ### [Structured cabling](https://telxpress.com/glossary/structured-cabling/) Structured cabling is the standardized, organized system of copper and fiber cables, patch panels, racks and outlets that connects every phone, computer, access point, camera and room system in a building to the network. - Network ### [PoE (Power over Ethernet)](https://telxpress.com/glossary/poe/) Power over Ethernet (PoE) delivers power to devices such as phones, Wi-Fi access points, cameras and room controllers through the same network cable that carries their data, so no outlet is needed at the device. - Network ### [Wi-Fi 6, 6E and 7](https://telxpress.com/glossary/wi-fi-6-6e-7/) Wi-Fi 6, 6E and 7 are the most recent generations of wireless networking; each handles more devices in a crowded office with less delay, and 6E and 7 add the less congested 6 GHz band. - Network ### [Packet loss](https://telxpress.com/glossary/packet-loss/) Packet loss is the share of packets that never reach their destination; on a voice or video call even a small amount causes dropped words, frozen video and a line that seems to cut out. 03 At Telxpress ## Where this shows up *at Telxpress* The pages and articles where this term does real work: what we advise, build and support. - Page ### [Structured Cabling & Fiber Installation](https://telxpress.com/solutions/business-technology/cabling/) Structured cabling, fiber, racks and clean terminations for new builds, expansions and office moves across Orange County, installed by our own team. - Page ### [Business Networking, Firewalls & Managed Wi-Fi](https://telxpress.com/solutions/business-technology/networking/) Switching, routing, Fortinet firewalls, Ubiquiti and Cisco Meraki Wi-Fi and managed network services for offices that depend on reliable connections. - Page ### [Conference Room AV & Digital Signage](https://telxpress.com/solutions/business-technology/audio-visual/) Conference rooms, displays, video conferencing, digital signage and sound systems designed for AI-enabled meetings and installed by our Irvine team. 04 Sources ## Public *references* The standard or law this definition rests on, as published by its owner.
