NB-IoT has four characteristics:
One is wide coverage, which will provide improved indoor coverage. In the same frequency band, NB-IoT has a gain of 20dB compared to the existing network, which is equivalent to improving the coverage area by 100 times
The second is the ability to support connections. One sector of NB-IoT can support 100,000 connections, supporting low latency sensitivity, ultra-low device cost, low device power consumption, and optimized network architecture;
The third is lower power consumption, the standby time of the NB-IoT terminal module can be as long as 10 years;
The fourth is lower module costs, and the company expects a single continuous module to not exceed $ 5.
