GSM modem
To each homebase, a GSM modem can be connected, which ensures a reliable and cheap Internet connection without the necessity to be connected to the existing Internet network in the building.
The GSM modem includes a SIM card, which can work within the EU at any mobile phone operator that has the 2G/3G signal coverage available in the particular region.
In contrast to different technologies (Lora, Sigfox, NB-IoT), it is not necessary to deal with a special signal coverage only for IoT and it is not necessary to purchase other expensive devices to receive or intensify the signal.
