A layered architecture, linked wirelessly at the field.
Wireless-first BMS is a specific engineering choice—particularly suited to retrofits, distributed sites and infrastructure where conventional communication cabling costs are high or disruptive.
Communication cabling runs between distributed controllers and BMS servers. Well-established, but retrofit-intensive and less flexible to expand.
Zigbee mesh replaces conventional inter-controller cabling. Local equipment interfaces (RS485/Modbus RTU) remain. Faster to commission, easier to expand.
Wireless field mesh, backbone via wired IP. Recommended for critical infrastructure where segments benefit from wired redundancy.
Six well-defined layers, engineered end-to-end.
Segmentation, credential hygiene, encrypted transport where supported, role-based access on the dashboard, and monitored gateway ingress. Cybersecurity is a project-wide discipline—not a single-product claim.
Controllers hold last-known state locally. Gateway buffers during transient network events. Critical outputs default to safe positions on communication loss. Redundancy and fail-safes are engineered per project.
Site survey, device density, mesh topology and interference profiles are engineered per building. Zigbee alone doesn’t guarantee performance—RF design does.
The NUOS platform can feed data upstream to supervisory/enterprise platforms via standard interfaces where required by the project.
