This article will explain in detail what the characteristics of nb-lot technology are, the editor thinks it is very practical, so share it with you for reference. I hope you can get something after reading this article.

NB-IoT is a new technology of narrowband Internet of things based on honeycomb in the field of IoT. Its main features are: 1, wide coverage, can achieve higher 20db coverage gain than GSM; 2, many connections, up to 100000 connections per cell; 3, low rate; 4, low cost; 5, low power consumption; 6, excellent architecture; 7, stable and reliable; 8, high security.

NB-IoT (Narrow Band Internet of Things, NB-IoT) is a new technology in IoT field based on cellular narrowband Internet of things, which supports cellular data connection of low-power devices in the wide area network, also known as low-power wide area network (LPWA). NB-IoT consumes only about 180KHz frequency band and can be directly deployed in GSM network, UMTS network or LTE network to support efficient connections of devices with short standby time and high network connection requirements.

Its main features are: wide coverage, many connections, low speed, low cost, low power consumption, excellent architecture, stable and reliable, and high security.

NB-IOT uses the License band and can be deployed in three ways: in-band, protective band or independent carrier.

Advantages of NB-IoT technology

1. Massive connections: 100000 connections per cell; NB-IoT has 50-100 times higher uplink capacity than 2G/3G/4G, which means that NB-IoT can provide 50 times more access than existing wireless technology in the case of the same base station.

2. Ultra-low power consumption: battery life up to ten years

The energy consumed by communication equipment is often related to the amount of data or rate, that is, the size of the data packet per unit time determines the power consumption. If the amount of data is small, the modem and power amplifier of the device can be adjusted to a very small level. NB-IoT focuses on small data volume and low speed applications, so the power consumption of NB-IoT devices can be very small and the battery life can be guaranteed for more than 5 years.

3. Deep coverage: it can achieve higher 20db coverage gain than GSM.

NB-IoT increases the 20dB gain than LTE, which is equivalent to a 100x increase in transmission power, that is, a 100x increase in coverage, even in underground garages, basements, underground pipelines and other places where signals are difficult to reach.

4. Stable and reliable: it can provide carrier-level reliable access and effectively support IoT applications and smart city solutions.

NB- IoT is directly deployed in GSM network, UMTS network or LTE network, and can be reused with existing network base stations to reduce deployment costs and achieve smooth upgrades. However, a separate 180KHz band is used to ensure that traditional services and future Internet of things services can be carried out stably and reliably at the same time. Taking the application of intelligent meter reading as an example, compared with the data recovery success rate of wired PLC, NB-IoT can ensure that the successful data recovery rate can reach 99%, and the reliability is greatly improved.

5. Security: inheriting 4G network security capabilities, supporting two-way authentication and strict encryption of empty ports to ensure the security of user data
