Cat 6A just overtook Cat 6 In 2026, for the first time, IT teams spent more money on Category 6A cabling than on Category 6, measured in dollars, not units installed. Frank Straka flagged the crossover at the BICSI Beyond 2026 conference, where I sat in the room and watched the numbers land. BSRIA's 2025 market data had put that crossover a year or two out, in 2027 or 2028 but the market got there first. It’s not a coincidence though. Five technology trends are converging at once, each one pushing infrastructure teams toward Cat 6A on their own. Together, they make a Cat 6 install look like a short-term fix inside a long-term commitment. What Does Cat 6A Deliver That Cat 6 Doesn't? Cat 6A runs at 500 MHz and holds a steady 10-gigabit connection across the full 100-meter channel. Cat 6 runs at 250 MHz and tops out at 1 gigabit reliably. Cat 6 can claim 10G in some setups, but signal interference from neighboring cables gets worse as speeds climb. Cat 6A cable also uses thicker conductors. That single spec difference shows up in every trend below. Five technology trends are converging at once, each one pushing infrastructure teams toward Cat 6A on their own. Together, they make a Cat 6 install look like a short-term fix inside a long-term commitment. Why Does Every New Wi-Fi Generation Push You Toward Cat 6A? Every Wi-Fi generation since Wi-Fi 5 needs a 10-gigabit uplink to hit its rated speed. That means Cat 6A is necessary behind the access point, not Cat 6. TIA's TSB-162B standard calls for a minimum of two Cat 6A cables per access point, and four per planning cell in a standard deployment grid. Wi-Fi 7 (802.11be) makes that two-cable rule non-negotiable. Its peak speeds can saturate a single 10G uplink on their own, so the standard calls for two Cat 6A runs per access point, combined to carry the load. The scale ahead is real: The Wi-Fi 7 market was worth $2.6 billion in 2025 and is projected to reach $24.2 billion by 2030 — a 56.2% compound annual growth rate. Wi-Fi 6, 6E, and 7 chipsets combined already represent a $33 billion market, projected to reach $67 billion by 2030. Every one of those radios needs cable behind the ceiling tile that can keep up. Why Do High-Wattage PoE Devices Need Cat 6A, Not Cat 6? IEEE 802.3bt — PoE++ — delivers up to 99 watts over a single network cable. That's enough to run, with no separate electrical line: A wireless access point An IP security camera with onboard AI processing A digital signage display A smart lighting controller Heat is the catch. Bundle multiple high-wattage cable runs in the same tray and they warm each other and warmer conductors carry power less efficiently. Industry testing presented at BICSI Beyond shows Cat 6A's thicker conductors run cooler in dense bundles than Cat 6 or Cat 5e, so you can pack more cables into a tray without the devices on the other end losing watts. Run high-wattage PoE devices over Cat 6, and you may not be delivering the power those devices are rated for. Why Does the IoT Buildout Need Cat 6A as the Baseline? There were 18.8 billion connected devices worldwide in 2024. By 2030, that number is projected to reach 39.5 billion. In enterprise and commercial environments alone, connected business devices are expected to grow from 4 billion to 9 billion over the same stretch. Smart buildings drive a big share of that growth. These are increasingly wired on Cat 6A as the baseline: Occupancy sensors HVAC controls Smart lighting Environmental monitors Access control panels The American Council for an Energy-Efficient Economy (ACEEE) found that buildings with properly functioning smart control systems can cut HVAC energy use by up to 18%, plug-load consumption by 28%, and lighting use by 33%. All of that runs on the cable you spec today. Cut a corner there, and you cap what the building management system above it can ever deliver. How Are AI Agents Changing the Math for Every Desk? Here's a trend that doesn't show up in a cabling standard yet but will: the assumption that one office connection serves one person doing one thing at a time is losing ground. Today's AI tools mostly wait for you to ask something a prompt in, a response out. Enterprise AI is moving toward persistent agents instead: software that runs continuously in the background, handling research, analysis, scheduling, drafting, and tool calls while you work on something else. These agents don't pause between queries. One BICSI Beyond speaker put it this way: traditional IT traffic is episodic, with “predictable quiet” between bursts. Persistent agents are “continuous, never idle.” For your network, that means a workstation running an active AI agent may generate real background traffic context exchanges, API calls, data retrieval at the exact moment the person at that desk is on a video call or working in an application. A 1-gigabit connection that was plenty for one person doing one task starts to look tight once that person effectively shares the connection with a second, constant participant. Cat 6A's 10-gigabit capability is the headroom a workstation may actually need over the life of a cable run installed today. Cable installed in walls and ceilings today could still be supporting your team in 2032. If you spec for what's already in the building and skip what's coming, you could be looking at an expensive oversight down the road. How Long Does a Cat 6A Investment Actually Last? Research presented at BICSI Beyond estimates that Cat 6A infrastructure deployed with two runs per wireless access point for link aggregation will support network demands through at least 2040. That's roughly 15 years of runway from today. The market data backs it up. Cat 6A revenue doubled from 2018 to 2024 and is projected to double again by 2030. Organizations building or refreshing infrastructure right now are running the same math and landing on the same answer. Specifying Cat 6A over Cat 6 costs a little more at install. Running Cat 6 into a building that needs to support Wi-Fi 7 radios, 90-watt PoE devices, and AI agent workloads for the next 20 years costs a lot more later in remediation work and capability gaps you didn't plan for. What Should You Spec for Your Next Install? If you're planning a new structured cabling deployment, or refreshing an existing one, every trend above points to the same spec: Cat 6A is the minimum viable cable for what's plugged in today, and almost certainly for what gets plugged in through 2040. Spec Cat 6, and you're making a short-term infrastructure decision inside a long-term installation. The 2026 revenue crossover isn't a marketing milestone. It's a signal that the industry already ran this calculation. Infrastructure teams got to that conclusion before the analysts did.
