The difference the iFrogLab NB-IOT WNB301H and WNB303R module are that.

#. WNB303R is able to adjust the frequency range by using the full frequency band of the joint MKT chip.

#. WNB301H is used in the frequency range of only 698-960 MHz and 1695-2180 MHz using HiSilicon chips


Advanced Solutions WNB301H is high performance NB-IoT module with extremely low power consumption for long battery life up to 10 years. The ultra-low power design is applied at system level, in the different 3GPP modes of operation. WNB301H supports various interfaces such as UART, I2C, SPI* and so on. The module provides customer high flexibility for different kind of applications. Due to the compact form factor, ultra-low power consumption and good performance, WNB301H is the best choice to be embedded to the design or solution for SmartX applications, ex. smart cities, smart metering and grid, security and asset tracking, environmental monitoring and control, health care monitoring, etc.
