What is NB-Fi Transceiver ?

The RF transceiver is a device which houses functions of both transmitter and receiver in a single device. The transmitter part transmits baseband information on RF modulated signal as per NB-Fi frequency. The receiver part does the reverse operation. Transmitter does up conversion where as receiver does down conversion. NB-Fi transceiver is a programmable modem used for long range communication for IoT LPWAN applications with ultra low power.
