Radio channel operation
The basis of the LPWAN technology data transfer principle (based on the NB-IoT protocol) at the physical level is the property of radio systems - an increase in the communication range with a decrease in the transmission speed.
A distinctive feature of NB-IoT is the use of the existing infrastructure base of mobile operators. The licensed frequency spectrum is used for data transmission. The following bands are defined in Russia — B20 (800MHz), B8 (900MHz) and B3(1800MHz).
A device with a NB-IoT module transmits data over the air to a base station. The station receives signals from all devices within its range and transmits to a remote server. The data obtained on the server is used to display and analyze data, build reports and make decisions.
