Low Power Consumption

NB-IoT technology focus on the small data and small transmit speed application. So NB-IoT device power consumption can be very small, the device life can be significantly increased from a few months to several years.


NB-IoT does not need to re-build the network, radio and antenna are multiplexed.For example, like one of China’s network operators-China Mobile, there is a wider band in 900MHZ owned by China Mobile. Only need to allocate part of the 2G band, you can directly deploy LTE and NB-IoT at the same time. Low speed, low power consumption and narrow bandwidth also bring the advantage of low cost to NB-IoT chip and module.

Wide Coverage Area

NB-IoT has better indoor coverage capability than LTE. NB-IoT has enhancements of 20dB gain more than LTE, it is equivalent to an increase of 100 times coverage area capacity more than LTE.

Numerous and Powerful Nodes Connection

The Four-Faith LoRa module adopts a LoRa modulation technique, acquired through many years of wireless network experiences to achieve a maximum transmission distance of 8 km. Perfectly solving the problematic environment of small amounts of data transmission over long distances, providing an ideal solution for all industrial wireless networking needs.
