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 few months to several years.
NB-IoT need not to re-build the network, radio and antenna are basically multiplexed.For example, like one of China 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 the 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
In the case of the same base station, NB-IoT can provide 50-100 times access nodes more than existing wireless technologies.One sector can support 100,000 connections with low latency sensitivity, ultra-low device cost, low device power consumption and optimized network architecture.
