① Gateway load&zoning
Deploy one wireless RCU gateway per room or floor; plan subnets by wall material and distance; suites and connecting rooms get separate gateways or repeaters.

Wireless Guestroom Control
Wireless hotel RCU retrofit — Mesh / ZigBee gateways with wireless panels and card-power modules; minimal wall damage for renovation hotels.
- 3–7 days Single-room wireless retrofit
(typical partial renovation) - 70%+ Low-voltage chase work saved
(depends on existing wiring) - 128–256 Points per gateway
(by protocol&layout) - 4 Wireless protocol options
Mesh · ZigBee · LoRa · Hybrid
* Schedule and load figures are engineering ranges; tender docs should state "subject to mock-up room and low-voltage survey".
Wireless engineering essentials · Four decisions first
For tenders, fix networking and power before panel silk-screen — table below reflects PurePoint Smart wireless project conventions; models per signed BOM revision.
② Panel power type
Battery keys suit minimal wall opening; live/neutral wireless suits always-on scene keys. Bedside and entry per contract branch selection.
③ Mains wiring still required
Wireless saves low-voltage runs only; card power, HVAC, and curtain motor mains circuits follow single-room wiring diagrams; relay modules in enclosure.
④ Local scene persistence
Welcome, vacant, and card-power linkages stored locally on gateway/host; room execution unaffected offline; upper system sync optional.
Retrofit schedule comparison
Switch by property type — for tender "technology route" chapter and closure plan; compare withwired solution.
| Comparison | Wireless RCU | Wired RCU | Hybrid (wired backbone + wireless endpoints) |
|---|---|---|---|
| Schedule | Interleaved with fit-out; low-voltage 5–10 days/floor | Full fit-out low-voltage 15–25 days/floor | 12–18 days/floor |
| Cabling | Gateway power + minimal runs to box; panels wireless | Star low-voltage to each panel | Riser bus + wireless bedside/bath |
| Best for | Boutique chains, tight-schedule new build | Full-fit luxury, stability priority | Standard room wired + suite wireless extension |
| Risk | Wall shielding needs survey; battery O&M | Chase cost and schedule | Two protocol doc sets to align |
| Comparison | Wireless RCU | Wired RCU | RS485 bus retrofit |
|---|---|---|---|
| Schedule | 0.5–1 day/room; 3–5 days/floor | Chasing 5–8 days/floor | Conduit 4–6 days/floor |
| Cabling | Gateway near LV box; wireless card power/panels | Full-room low-voltage rewire | Single bus + module addresses |
| Best for | Legacy hotels, economy upgrades | Full renovation, floor closure OK | Chain standard stores with existing conduits |
| Risk | Metal partitions affect signal; budget battery swaps | Revenue loss from closure | Address conflicts and terminal matching |
| Comparison | Wireless RCU | Panel swap only (keep existing wiring) | Modular chassis add-on |
|---|---|---|---|
| Schedule | 2–3 days/room (no full-floor closure) | 1–2 days/room | 3–4 days/room (add circuits) |
| Cabling | Add gateway + wireless modules; mains unchanged | Reuse existing low-voltage | Swap modules in box; minor LV adjustment |
| Best for | B&B, boutique rooms, mock-up first | Legacy system OK, UI upgrade only | Need more circuits for HVAC/curtains |
| Risk | Coexistence with legacy needs VLAN isolation | Features limited by legacy host | Enclosure space and cooling |

Wireless hardware topology · Layer guide
Network structure
Three layers as left diagram:input layerwireless scene panels, door sensors, PIR, card-power switches → in-roomwireless gateway(local scene execution) →output layerrelay modules drive curtains, HVAC, and controlled outlets.
- Chain: wireless panel / sensor → wireless gateway → output modules
- Mesh / ZigBee / LoRa by property structure; gateway usually in LV box with power and Ethernet
- Optional integrator upper system to PMS; offline does not affect in-room execution
Delivery boundary
PurePoint Smart primarily deliverslower two hardware layers: gateway, wireless terminals, relay modules, and terminal tables; excludes PMS, mini-program, and group cloud software.
- Single-room wiring diagram + wireless network table with BOM
- Fields mapped by integrator perprotocol integration
- Hybrid projects need separate network isolation notes
Input wireless terminals → in-room wireless gateway → output relays/modules → lighting, HVAC, curtain mains; optional uplink to integrator gateway / PMS. PurePoint Smart delivers gateway-to-terminal hardware and docs; software by integrator.Engineering docs download →
Survey and acceptance checklist
Signal survey
Measure RSSI in mock-up room; log metal door frames and elevator-adjacent rooms; add repeaters or live/neutral panels if needed.
Gateway power
LV box needs 220V and Ethernet; document gateway vs card-power main switch in scene table (vacant room gateway may standby).
Battery O&M
Tender lists battery model and replacement cycle; test card permissions, card power, and full scene chain.
Per-room sign-off
Test Welcome, card-out delay, DND door sign 3× each; attach toenergy-savingacceptance pack.
