GSM is the global standard for digital mobile cellular communications. Lighting control via GSM allows you to individually control the luminaires without additional intermediate equipment. GSM modules do not require the deployment of a new network and operate without a central controller. The technology of work on existing networks of the GSM standard allows you to connect tens of thousands of devices in the coverage area of one base station - sensors, sensors, counters, both indoors and in open spaces with difficult signal passing conditions.
