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.
Atlas industrial switches — industrial-scenario access layerOur own industrial line — compatible with any brand's core layer.

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.

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.

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.
