What PoE Budget Do Wi-Fi 7 Access Points Need, and Which Switches Deliver It?

Wi-Fi 7 PoE Requirements: How Much Power, and Which Switches 

Wi-Fi 7 is the reason a lot of access switches are about to look underpowered. Not in throughput, in watts. Here's what the access points actually need, and how to make sure the switch can feed a whole floor of them, not just one on the bench. 

What PoE Budget Do Wi-Fi 7 Access Points Need? 

Most enterprise Wi-Fi 7 access points draw roughly 35 to 50 watts with all radios and features enabled, and want 802.3bt power, Type 3 (60W), for full operation. They will run on 802.3at PoE+ (30W), but in a reduced mode with some capability disabled. Plan for about 50 watts per AP, delivered by an 802.3bt switch port. 

That's per access point. The number that catches designs out is the total. 

The PoE Standards, and What Each Powers 

Power over Ethernet comes in tiers, and the jump Wi-Fi 7 forces is from PoE+ to 802.3bt: 

For Wi-Fi 7, the target row is 802.3bt Type 3. Type 4 (90W) buys headroom for the most demanding APs and future devices. 

Do Wi-Fi 7 APs Work on PoE+? 

Yes, but with a catch, and it's model-dependent. Cisco's Wi-Fi 7 access points can operate on 802.3at PoE+ (30W), but at that level some run with reduced functionality, features, radios or the USB port switched off to fit the power (Cisco Wireless Wi-Fi 7 access points). 

It varies by model. A lower-end Wi-Fi 7 AP may run fully on PoE+. A higher-end one may need 802.3bt to enable USB, or 4-pair 802.3bt to unlock all features and dual-port redundancy. 

So "it works on PoE+" is true and misleading at once. It powers on; it may not perform. If you want the AP you paid for, feed it 802.3bt. Check each AP model's requirement rather than assuming. 

Per-Port Power vs Total PoE Budget: The Maths That Trips Designs 

This is the mistake that turns a good spec into an under-powered floor. A switch quoting "90W per port" does not mean every port can deliver 90 watts at once. The switch has a total PoE budget, set by its power supplies, and every powered device draws from that shared pool. 

Do the sum. Forty-eight Wi-Fi 7 APs at 50 watts each is around 2,400 watts of PoE demand. If the switch's total budget is lower, it can't power them all at full draw, however high its per-port figure, and some APs drop to reduced mode or don't power at all. 

The fix is to size the switch's total PoE budget, and its power supplies, to the sum of the APs it feeds, usually with redundant, high-wattage supplies. Per-port class tells you a port can power one Wi-Fi 7 AP. Total budget tells you the switch can power the floor. 

Which Cisco Switches Deliver Wi-Fi 7 PoE? 

The Catalyst 9300 and 9300X. They support 802.3bt, delivering 60W UPOE and 90W UPOE+, with high-density options and the total PoE budget, via dual power supplies, to feed a full complement of high-power APs (Cisco Catalyst 9300 data sheet). 

Crucially, the same switches provide multi-gigabit ports, which matters because a Wi-Fi 7 AP exceeds a gigabit and would be throttled on a 1G port. So the right Wi-Fi 7 access switch does two things at once: high 802.3bt power and mGig. A switch that offers one without the other only half-solves the upgrade. 

Do You Also Need mGig for Wi-Fi 7?

Yes. A Wi-Fi 7 access point can push well over a gigabit, so connecting it to a 1G port throttles it regardless of power. Wi-Fi 7 access ports should be multi-gigabit, 2.5G or 5G at least, on top of 802.3bt power. Power and speed are a pair for Wi-Fi 7, not separate choices. 

Getting the Access Layer Right for Wi-Fi 7 

Sizing 802.3bt power, the total PoE budget and mGig together, so the switch feeds and connects a whole floor of Wi-Fi 7 APs, is exactly the design detail that decides whether a wireless upgrade delivers or disappoints. 

Proactive Data Systems, a Cisco Preferred Partner with 35 years of experience and more than 1,500 customers, sizes the access layer for Wi-Fi 7: the right 802.3bt switches, a total PoE budget that holds under full load with redundant power, and mGig where the APs connect.
