Power Line/RF Bridge for Streetlight Control Networks
In a managed streetlighting solution with extremely low pole-to-transformer ratios (as low as 1 to 1) or extremely high electrical noise, you can use the PL/RF Bridge to connect segments of lights with a point-to-point RF connection. Management and monitoring of power line and PL/RF hybrid segments is seamless.
Features
- Provides reliable streetlight control and communications in even the worst electrical environments
- Mounts easily on streetlight fixtures into ANSI-standard twist-lock sockets; LED indicators provide visual confirmation of streetlight/RF connection
- Does not require additional installation tools
- Uses the same management tool as an all power line segment, without requiring additional software updates
- Brings many segments to one SmartServer streetlight segment controller, reducing hardware and WAN operating costs

SmartServer Controller
In our managed streetlight solution, the SmartServer follows rules to operate a segment of streetlights, invoking on/off time and sequencing, dimming time and percentage, and other functions. It also logs data such as energy use, provides alarms, and connects the segment to third-party system software via the city’s IP network.
