A typical narrowband IoT technology architecture is a three-layer, application scenario

Sensing layer, network layer, and application layer.

Sensing layer: It is composed of various sensors, including temperature and humidity sensors, QR code tags, RFID tags and readers, cameras, infrared lines, GPS and other sensing terminals.

The sensing layer is the source of the IoT to identify objects and collect information. lte iot module If the network Internet of things is compared with a person, the perception layer is the sense organs, such as eyes, nose, ears, skin, etc.

Network layer: consists of various networks, including Internet, radio network, network security management control system and cloud computing technology platform, etc. It is the hub of the whole IoT, responsible for transmitting and processing the information obtained by the student perception layer.

Narrowband Internet of things through the network layer is equivalent to the human nervous system, transmission and various data signals.

Application layer: It is the interface between the Internet of things and the user. It is combined with the needs of the industry to realize the intelligent application of the Internet of things. The application layer of IoT is equivalent to human brain, which is responsible for analyzing and processing various data.

NB-IoT technology application scenes

It is widely used in oil field, oil well, gas field, steam pipeline, heating system pipeline, water pump room, refrigeration, storage, agricultural development shed, breeding and other environments for real-time information monitoring and early warning.

Widely applied in the machine room, the power of the station, the environment for monitoring and management system, low-voltage distribution monitoring and control technology system, power data can monitor and control system, factory machine learning equipment, production line operation working condition monitoring system, production cost information collection system and other wireless monitoring and early warning.

Do IoT jobs have a demand?

The research notes that the market for Internet of Things (IoT) security products is experiencing strong growth due to rising demand for connected devices including smart automobiles, smart meters, and machine-to-machine (M2M) interactions.

LTE Cat 18: Is it good?

Through the early stages of 5G, Cat 18-Cat 18 ultra-high-speed LTE will undoubtedly continue to rank among the fastest wireless wide-area network options.

LTE: Is it superior to 4G LTE?

What makes 4G and LTE different from one another, and which is better? In summary, 4G provides access to a wider range of online activities, more stability, and a significantly faster speed. In comparison to the fourth generation, LTE's performance suffers because it is halfway between 3G and 4G.

Can a laptop with LTE make calls?

LTE is an exclusive data network. You can make calls in the LTE network if the network supports VoLTE, which is the mobile equivalent of VoIP. You can only utilize LTE and cannot make calls if you are using a carrier that doesn't offer VoLTE.

Is VoLTE equivalent to 5G?

Although 2G and 3G do not enable VoLTE, VoLTE services are not available for networks below 4G. However, VoLTE supports 5G LTE devices and enables 5G users to effectively and uninterruptedly use voice over services.
