The Wireless Network Bridge family extends BACnet MS/TP, BACnet/IP, LonWorks, and Ethernet networks beyond the confines of individual buildings. This enables coordinated control of interior and exterior lighting, as well as other building loads, without costly building-to-building conduit runs or the maintenance associated with water seepage that can occur with direct burial.

• Synchronous point-to-multipoint communication
• Antenna options for close or long range wireless connectivity
• Maintains network architecture for optimal performance
• Encryped for secure data delivery
