What is NB-IoT

NB-IoT refers to "narrowband Internet of Things" and is an emerging technology in the IoT field that supports cellular data connections of low-power devices in wide area networks, also called low-power wide area networks. NB-IoT supports efficient connection of devices with long standby time and high network connection requirements.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and consumes only about 180kHz of bandwidth. It can be directly deployed on GSM networks, UMTS networks or LTE networks to reduce deployment costs and achieve smooth upgrades.

NB-IoT is an emerging technology in the IoT field that supports cellular data connections of low-power devices in wide area networks, also called low-power wide area networks (LPWAN). NB-IoT supports efficient connection of devices with long standby time and high network connection requirements. It is said that NB-IoT device battery life can be improved by at least 10 years, while also providing very comprehensive indoor cellular data connection coverage.

NB-IoT has four major characteristics: First, 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 a 100-fold increase in coverage. The second is the ability to support connections. One NB-IoT sector can support 100,000 connections, supporting low latency sensitivity, ultra-low equipment cost, low equipment power consumption and optimized network architecture; the third is Lower power consumption, the standby time of NB-IoT terminal modules can be as long as 10 years; fourth, lower module cost, enterprises expect a single connected module to be no more than 5 US dollars.

NB-IoT focuses on the Low Power Wide Coverage (LPWA) Internet of Things (IoT) market and is an emerging technology that can be widely used around the world. It has the characteristics of wide coverage, multiple connections, low speed, low cost, low power consumption, and excellent architecture. NB-IoT uses License frequency bands and can be deployed in three ways: in-band, guard band or independent carrier, coexisting with existing networks.

Because NB-IoT has the advantages of low power consumption, wide coverage, low cost, and large capacity, it can be widely used in a variety of vertical industries, such as remote meter reading, asset tracking, smart parking, Smart agriculture, etc.
