Quebec City's first managed-streetlight system was installed in the historical district of Charlesbourg to highlight the buildings' architecture. The lights add charm, especially in winter, making the area more attractive to tourists and residents. Photo: Echelon Corp.

Streetlights equipped with electronic ballasts communicate with the segment controller using power line communication and IP protocol. The segment controller provides operational data to, and receives control signals from, remote users via a Web portal. Illustration: Echelon Corp.


Quebec City's remotely controlled and monitored streetlight system uses Echelon's LonWorks power line technology and i.Lon Internet servers to reduce energy use at times of peak demand. Shown in this image are the street controller with the segment controller (mounted, upper right), energy submeter, and modem connection to the wide-area network. Photo: Echelon Corp.
