Partner kit · Typical topologies
Four typical topologies, from the studio flat to the whole estate
For planners: the network and radio topology of the system, shown for the four configurations found in real projects. Each diagram is followed by its table of links: medium, constraint, responsible trade. The exact positions and quantities for your project appear in the provisions drawing, drawn up by Neolia once it has checked your drawings.
The reference configuration
| Link | Medium | Constraint | Trade package |
|---|---|---|---|
| Operator feed → router | Fibre (ideally) | Subscription paid by the building (property manager) | Telecom operator / property manager |
| Router → PoE switch | Ethernet Cat 6 | In the plant room · the 802.3at PoE switch is part of the active equipment: in new builds the electrician buys it to the specified references; in renovation Neolia supplies it | Electrician (cabling and, in new builds, switch) · Neolia (switch in renovation) |
| PoE switch → door station | Cat 6 in empty conduit | Max length 100 m · PoE 802.3at | Electrician |
| Door station (relay) → door release | 2 wires | Door release supply 12 / 24 V, AC or DC depending on the model, close to the door | Electrician |
| Router → LoRaWAN gateway | Ethernet Cat 6 + 230 V | Mid-level or high point recommended, in a clear position | Electrician |
| Gateway → meters and sensors | LoRaWAN radio (EU868, 8 channels) | Coverage confirmed by the micro-survey, tested at commissioning · about 2000 measuring points per gateway | No wiring |
One plant room, one door station per stairwell
The router, the PoE switch and the gateway are shared: only the Cat 6 cable multiplies, one per door station, each limited to 100 m. If a stairwell is too far from the plant room, the opening schedule provides for the intermediate distribution point. On price, the count is per stairwell. On new builds, the active equipment is priced within the electrical works package, to the references we specify. On renovations, from 8 units per stairwell, the equipment and its installation work are at our expense, and below that threshold 2,000 CHF per stairwell, once. Everything else is shared at no extra cost.
Two gateways, decided on the drawings
As soon as the building is long, tall, split into several blocks or built in dense concrete, the micro-survey may call for a second gateway: all it takes is a Cat 6 cable left ready at the defined point (high point of the riser, roof space, another block) and a 230 V supply. With no effect on the price: the number of gateways is a survey parameter, not a chargeable option. If in doubt at drawing stage, run the spare Cat 6: it costs a few francs during structural work and saves drilling later.
If the project requires wired infrastructure
An existing stock of M‑Bus meters, or a client who prefers wiring: readings then come through a 2-wire M‑Bus riser and a concentrator in the plant room. Everything else is identical: PoE door station, platform, statements, resident app. This variant brings back the metering wiring that the LoRaWAN topology removes: it mainly makes sense in a refurbishment, when the riser is already there.
Your project fits none of these cases?
