Enterprise Campus Network Solution: Wired + Wi-Fi That Just Works — Offices, Hotels, Schools

One flat network where everything slows down at 9 a.m. is not a design. We engineer campus networks from your requirements, with the equipment brand chosen openly at design stage: access-aggregation-core layering, Wi-Fi planned from your floor plan, PoE power to APs and cameras over the data cable, VLAN isolation between departments and guests, and internet-behavior policy at the edge — sized honestly at 50, 200 or 1000 terminals.

Why Office Networks Fall Over

Four patterns we see in almost every building that calls us:

Wi-Fi dead zones & dropsCoverage planned by guesswork: one AP per floor, meeting rooms fighting for airtime, calls dropping as people walk between floors.
One flat networkPrinters, guests, cameras and finance share one broadcast domain — one cable loop or one infected laptop takes everything down.
A socket for every deviceAPs on the ceiling, cameras in corridors, phones on desks — powering each one separately doubles the cabling and the failure points.
Nobody to run itNo IT team on site — when something breaks, troubleshooting means rebooting switches one by one until it works again.

Architecture: Access — Aggregation — Core

The same layered structure used in carrier and headquarters campus designs, scaled to your building:

INTERNET EDGE CORE ACCESS · PoE ENDPOINTS Internet / ISP Enterprise router (egress) Firewall · policy NAT · internet-behavior policy · guest portal lands here Core switch A Core switch B redundant pair 10G uplinks Access switch · floor 1 Access switch · floor 2 Access switch · floor 3 PoE PoE PoE Wi-Fi AP · PCs · IP phones Wi-Fi AP · PCs · printers Wi-Fi AP · IP cameras VLAN plan VLAN 10 · Staff VLAN 20 · Guest Wi-Fi VLAN 30 · Cameras VLAN 40 · IP phones VLAN 99 · Management same cables, isolated traffic per department Management cloud or on-prem — all switches & APs in one dashboard

Why us: our founder spent 13 years inside the Huawei partner ecosystem delivering carrier networks. The design discipline is the same — only the building is smaller.

Equipment Options

The solution is sized to your requirements and budget first — the same architecture can be delivered on several vendors' product lines. We help you choose by supply availability in your destination country, budget and your team's operating habits.

Huawei — enterprise campus, WAN and security linesMature ecosystem with a global service network.
ZTE Wantone — comparable datacom linesPrice-performance direction; supply runs smoother in some markets.
H3C — campus and data-center linesWidely deployed campus and data-center portfolio.

What the Design Delivers

Six things a properly engineered campus network does that an accumulation of home routers never will:

Layered & redundantAccess-aggregation-core with a redundant core pair at larger sizes — a failure in one floor closet stays in that closet.
Full Wi-Fi coverageAPs placed from your floor plan — walls and materials considered, seamless roaming between floors, high-density rooms get their own plan.
PoE over one cableAccess switches power APs, cameras and IP phones over the data cable; a UPS on the core rack rides through power cuts.
VLAN isolationStaff, guest, camera, voice and management traffic ride separate VLANs on shared hardware — guests get internet, never your file server.
Access control & internet policy802.1X or portal authentication where it matters, URL and application policy at the gateway, logs kept for audits.
One management dashboardCloud or on-premises management: every switch and AP on one screen, alarms raised before users start calling.

Three Sizes, One Design Logic

Tell us your terminal count — wired PCs + Wi-Fi devices + cameras + phones — and the tier tells you the shape of the network:

Numbers we design around:
1 AP ≈ 25–30 busy Wi-Fi clients — density, not headcount, sets the AP count
PoE budget: AP ≈ 15–30 W · IP camera ≈ 6–13 W · IP phone ≈ 4–7 W, summed per switch
Uplinks: 1G to the desk, 10G access→core — so the core never becomes the bottleneck
Scale tierTypical siteWhat the design includes
~50 terminalsSmall office · boutique hotel · clinicOne gateway, one or two PoE access switches, a handful of APs, a clean VLAN plan — everything in one cabinet, manageable remotely.
~200 terminalsOffice building · school · mid-size hotelCore switch with dual uplinks, PoE access switch per floor, dozens of APs with roaming design, structured VLAN and addressing plan, firewall at the edge.
~1000 terminalsMulti-building campus · university · resortRedundant core pair, aggregation per building or floor, engineered Wi-Fi roaming across the estate, dedicated management and authentication, PoE budgets calculated per closet.

Equipment Roles (Categories, Not Models)

The solution is built from these equipment categories — the brand is chosen with you at design stage. Exact models depend on your port counts, PoE budget and country — so we spec models after your requirements list, not before.

RoleWhat it does
PoE access switchesConnect and power desks, APs, cameras and phones on each floor; sized by port count and total PoE watts, not just ports.
Aggregation / core switchesConcentrate floor traffic on 10G uplinks and route between VLANs; deployed as a redundant pair at larger tiers.
WLAN access pointsCeiling and wall APs placed from the floor plan; controller function on hardware or in the cloud manages roaming and radio tuning.
Enterprise router (egress)Terminates the internet lines, handles NAT and — when you have more sites — the VPN tunnels to headquarters.
Firewall (optional)Adds intrusion prevention, URL filtering and internet-behavior audit at the edge — recommended from the 200-terminal tier up.
Management platformCloud or on-premises network management — topology view, alarms, configuration backup, so the network survives staff turnover.

Send us your requirements list — floor plans, terminal counts, camera counts — and the model list follows. That order keeps the design honest.

Design Notes & Honest Limits

Read this before you commit:
  • Wi-Fi quality is a floor-plan question. Concrete walls, mirrored glass and long corridors change everything — we ask for your plans before we promise coverage, not after.
  • PoE is a watts budget, not a port count. Cameras plus APs add up fast — we sum the load per switch and leave headroom, so nothing browns out on a hot day.
  • Licensing policy and product availability differ by brand and destination country. We check and confirm both for your country at the design stage — before you commit to anything.
  • Physical cabling is best done locally. We design the network and hand over a cable schedule per floor — local contractors run the cat6 and fiber cheaper and faster than anyone we could fly in.
  • If you are 15 people in one room, an enterprise campus design is overkill — a business-grade router and one PoE switch will serve you fine. We will tell you so if that is your case.

Field notes from our engineers

FAQ

Can one network carry office data, Wi-Fi, cameras and IP phones?
Yes — that is exactly what VLAN isolation is for. Staff data, guest Wi-Fi, cameras, phones and management each ride their own VLAN on the same switches and cables, so they share hardware without seeing each other's traffic.
How many Wi-Fi access points do I need?
It depends on floor area, wall materials and user density, not just headcount. As a rule of thumb one AP serves roughly 25-30 busy clients; meeting rooms and lobbies need their own planning. Send us a floor plan and we place the APs on it.
Can guest Wi-Fi be fully separated from company data?
Yes. Guests land in their own VLAN with internet-only access — they never see printers, file servers or cameras. A captive portal page can front the guest network if you want branded login.
Do I need an IT team on site to run this?
No. Every switch and AP reports into one management dashboard, cloud-based or on-premises. Most day-2 issues are visible and fixable remotely, and we hand over the network documented so any engineer can pick it up.
Can the network start small and grow later?
Yes — that is the point of the layered design. You can start with one core switch and a few access switches, then add floors, buildings or a redundant core without redesigning what is already running.
