LTE Lighting Gateway and sub-1 GHz RF mesh Lighting Controller
SGDC-D27-LC is a lighting gateway that provides LTE communication to connect to back end server and forwards control commands from server to RF lighting controller SGCM-W60-LC via RF mesh. SGDC-D27-LC also collects messages from SGCM-W60-LC and sends back to server. Both of them support lighting dimming control, relay on/off control, temperature and power measurement function as what NEMA node supports for street lighting control application.
