Hotel, 12,000 m2: 34 APs, IoT-heavy 8-VLAN fabric
Problem. A 12,000 m2 hotel spreads guest Wi-Fi, back-of-house operations, a large room-automation estate (locks, thermostats, GRMS), CCTV and the PMS across a big, low-density floor plate. The team needs an honest access-layer envelope — AP count, port count, PoE load and VLAN split — that reflects a footprint dominated by IoT endpoints rather than by concurrent human users.
Answer. At hospitality density the tool sizes 720 concurrent users, 34 Wi-Fi APs and 864 wired user ports; with 30 cameras and 200 IoT endpoints added, 1,128 total access ports land on 30 forty-eight-port switches and 1,467 Cat6A drops. The PoE load is about 2.4 kW, and because the profile is non-critical and the area sits below the enterprise boundary the tool settles on the commercial tier with 8 VLANs.

How this preset reads — the engineering view.
The calculator sizes the LAN from a building-profile density: users, APs and wired ports each scale off a per-m2 coefficient taken from Cisco, Aruba and Juniper Mist high-density design guides — conventions rather than a standard mandate. The hospitality profile runs a deliberately lower intensity than healthcare (0.06 users/m2, 0.0028 APs/m2, 1.2 ports/user), because a hotel is a large, thinly occupied floor plate where the endpoint count is driven by fixed room devices, not by a dense human population.
For this 12,000 m2 hotel the model returns 720 concurrent users and 34 APs (12,000 x 0.0028 = 33.6, rounded up). Wired user ports come to 864 (720 x 1.2); the PoE endpoints — 34 APs, 30 cameras and 200 IoT devices — add 264 more, for 1,128 total access ports. The 1.25 port-headroom factor over 48-port switches gives 30 access switches, and the 1.30 drop factor gives 1,467 Cat6A drops. The PoE budget is 34 x 25 W + 30 x 12 W + 200 x 6 W, about 2,410 W — roughly 2.4 kW, with the 200-endpoint IoT estate the single largest contributor. With 8 VLANs the design separates guest, back-of-house, IoT, CCTV and PMS traffic; the non-critical profile and the sub-20,000 m2 area put it on the commercial tier.
Every output tracks its input in a single direction: grow the area or user density and APs, ports, drops and switch count rise together; add rooms’ worth of IoT or more cameras and the PoE port count, PoE watts and drop count climb in step, which is why the IoT figure dominates the wattage here. Push the area past the profile’s enterprise boundary and the tier steps up; add VLANs to tighten segmentation without disturbing the physical port maths.
This is a provisioning envelope, not a distribution design. The tool does not lay out riser closets across the floors, size fibre uplinks or aggregation, model redundancy, or resolve where the 200 IoT endpoints physically home; it also does not cover guest-network captive-portal, PMS integration or room-controller commissioning, which sit in the hospitality-systems scope. Confirm the AP count with a predictive or on-site Wi-Fi survey before committing containment.
What this preset deliberately does not solve
- AP figure follows design-guide density conventions — verify with a real Wi-Fi survey.
- IoT endpoints are counted for ports and PoE only; homing, VLAN policy and commissioning are separate.
- Access-layer envelope only: no fibre uplink, aggregation, redundancy or core sizing.
How this preset differs from its siblings
This hospitality preset is the large-footprint, low-intensity case — 12,000 m2 at light user density where 200 IoT endpoints, not people, drive the PoE load, and the non-critical profile lets it settle on the commercial tier. The hospital preset is the inverse: half the area but far higher per-m2 density and a mission-critical flag that forces the enterprise tier and a richer 10-VLAN split. Use this preset when a big building with sparse users and a heavy device estate sets the shape; use the hospital preset when clinical density and hard segmentation do.
