NB-Fi

NB-Fi Protocol employs a Narrow Band technology that enables communication using the Industrial, Scientific and Medical ISM radio band (and in other parts of sub-GHz license-free spectrum as well).

NB-Fi devices could be manufactured using widespread electronic components which could easily be manufactured or purchased in every particular country. WAVIoT has developed an NB-Fi transceiver that encapsulates the NB-Fi protocol at a physical layer.

The NB-Fi transceiver^[3] supports 430–500 MHz and 860–925 MHz frequency bands at 50 to 25,600 bit/s data rates.

The network is based on one-hop star topology and requires a SDR-technology base stations to operate.^[4] The signal can also be used to easily cover large areas and to reach underground objects.^[5]

NB-Fi Protocol stack is currently implemented on:

• STM32L0x/STM32L4x Series microcontrollers (manufacturer: STMicroelectronics) with NB-Fi transceiver^[6] (manufacturer: WAVIoT) or AX5043 transceiver (manufacturer: ON Semiconductor);
• AX8052F143 with AX8052 MCU and AX5043 RF transceiver (manufacturer: ON Semiconductor).^[7]
