The SGDC-L38, SGDC-D28-LC, and SGDC-D23-LC are cellular street lighting controllers that provide directional connectivity from street lights to communication servers. The SGDC-L38 and SGDC-D28-LC adopt NB-IoT technology while the SGDC-D23-LC leverages LTE connectivity. In addition, a photo sensor and G-sensor are built in to the SGDC-L38 to provide light and drop detection.

The SGDC-D27-LC is a gateway that transmits and receives data to and from communication servers via LTE and forwards and collects data to and from the SGCM-W60-LC via sub-1GHz RF mesh. Both the SGDC-D27-LC and SGCM-W60-LC support on/off control, dimming, and power measurement of connected lights.
