Communication channels

The carrier frequence in unlicensed range:

  • 433 MHz
  • 868 MHz
  • 2400 MHz

Automatic network construction, high reliability of data communication.

GSM/GPRS
GSM/GPRS

The usage of the ready public comminication channels GSM/ GPRS and usual SIM-cards with dynamic IP-address - low costs on the system deployment. There are 2 slots for SIM-cards installation of other operators - high reliability of the data communication.

LoRaWAN
LoRaWAN

LoRaWAN is open protocol for high-capacity networks (one network includes up to 1 000 000 devices) with long range of operation (up to 10-15km in open areas, 4-5km in urban areas) and low power consumption.
