NB IOT focuses on small data volume and small speed applications, so the power consumption of Nb IOT equipment can be very small, and the endurance time of equipment can be greatly increased from the past few months to several years

The Nb IOT cellular wireless terminal does not need to be rebuilt, and the RF and antenna are basically multiplexing. Taking China Mobile as an example, 900MHz has a relatively wide frequency band. Only a part of 2G frequency band needs to be cleared, and LTE and Nb IOT can be deployed directly at the same time. Low speed, low power consumption
 

NB IOT has a strong indoor coverage, with a gain of 20dB higher than LTE, which is equivalent to a 100 times increase in coverage area capacity.

In the case of the same base station, the Nb IOT data acquisition terminal and the cellular wireless transmission terminal can provide 50-100 times of the access number compared with the existing wireless technology. A sector can support 100000 connections, low latency sensitivity, ultra-low equipment cost, low equipment power consumption and optimized network architecture.
