W-BACnet

BACnet MS/TP trough reliable wireless mesh.
W-BACnet replaces the cabling with a reliable wireless mesh eliminating the time-consuming installation planning, cabling, daisy-chaining and troubleshooting. With W-BACnet, it is easy to retrofit connectivity to already installed devices, instantaneously converting individually siloed devices to a wireless network. The product enables flexibility, saving time and costs, including during installation and steady-state operation.

The W-BACnet acts as a proxy for the connected BACnet MSTP device, effectively extending the bus and creating the possibility to make legacy products wireless. A W-BACnet network consists of a single W-BACnet Gateway with up to 100 W-BACnet Nodes. Connect your BACnet MS/TP controller using RS485 to the W-BACnet Gateway, and then each of your BACnet MS/TP devices with RS485 to the W-BACnet nodes.

The W-BACnet product is built upon LumenRadio’s patented meshing technology MiraMesh - providing ultra-reliable device-to-device connectivity, easy installation, concurrent Bluetooth and extended indoor range. MiraMesh is used in a large number of different applications around the world for building automation, HVAC control, lighting control and industrial sensor networks.

System overview

A W-BACnet network consists of a single W-BACnet Gateway with up to 100 W-BACnet Nodes. Connect your BACnet MS/TP controller using RS485 to the W-BACnet Gateway, and then each of your BACnet MS/TP devices with RS485 to the W-BACnet nodes.

The W-BACnet network is built on LumenRadio’s MiraMesh, a self-forming and self-healing wireless mesh technology.

FAQ

Is the communication in the network encrypted?

Yes, all communication in the W-Modbus Network is encrypted with AES128.

Can I connect several BACnet MSTP devices behind one W-BACnet unit?

The Gateway can be connected to an already existing RS485 bus, but each W-BACnet node can only be connected to one BACnet MSTP device.

Can multiple W-BACnet networks be installed in the same area?

Yes, as long as you commission one network at a time multiple networks can coexist next to each other.

How does W-BACnet work?

The W-BACnet devices acts as a proxy for each connected BACnet MSTP device, making it possible for all devices to be accessible over a wireless link.
