The personnel working in the Internet of Things industry will be familiar with the communication module. The communication module is the key link connecting the Internet of Things perception layer. There are many modules in the market, such as LoRa module, WIFI module, NB-IoT module, etc. Explain what is the communication module, what is the value of the IoT industry chain?

Explanation of the module

A module is a very broad concept. A module on a hardware is a fully functional system consisting of multiple components with basic functions. A module that conforms to a defined software is a collection of program statements that can only be individually named to perform a certain function independently. The definitions can be called modules. According to different functions, they can be divided into communication modules, positioning modules, photosensitive modules, etc. Most of the modules mentioned in the field of Internet of Things refer to wireless communication modules. In addition, Taiwan is used to calling modules as modules. Both are the same meaning.

In the Internet of Things era, the connection between objects and objects requires a wireless communication module to transmit and receive signals. The wireless communication module is a collection of peripheral circuits required for chips and chips. There is no uniform definition in the industry.

The wireless communication module enables various types of IoT terminal devices to have networked information transmission capabilities, and is an information portal for various types of intelligent terminals to access the Internet of Things. It is a key link connecting the IoT awareness layer and the network layer. The device data generated by all IoT awareness layer terminals needs to be aggregated to the network layer through the wireless communication module, and then the device is remotely controlled and controlled by the cloud management platform. Bring management efficiency improvements.

What is the value of wireless communication modules in the IoT industry chain?

In the IoT industry chain, there are chips upstream of the module and terminal applications downstream. Through the module manufacturers, the baseband chip, RF, memory chip, capacitor, resistor and other components are integrated to achieve its first value: hardware integration and software design, integrating multiple communication systems to meet different application scenarios. Environmental requirements simplify the work of application vendors.

Users do not need to understand the principle of radio communication, application vendors do not need to do their own complicated integration work, just need to buy the right product from the module manufacturer, you can use it directly.

The communication requirements between things are different. For example, a water meter needs to transmit less data, and it does not need to be transmitted every day. However, if it is a car, the amount of data it needs to transmit is very large. The real-time nature of the data is very high; other devices, such as street lights, home audio, etc., have their own communication needs.

These requirements make the module realize the second value in the IoT industry chain: the upstream of the wireless communication module is the production raw material such as the baseband chip, and the degree of standardization is high; the downstream is extremely dispersed for each subdivision application field. The IoT module itself is in the middle of the upstream standardized chip and the downstream decentralized vertical field, and needs to meet the specific needs of different customers and different application scenarios.

Shenzhen module manufacturers can purchase their own materials and design and sell their products. The production can be carried out by themselves or outsourced to the third factory. Manufacturers can customize development according to the requirements of different application scenarios by application vendors.

The full explanation of the communication module is as follows. It is classified according to different communication technologies. For example, the NB-IoT module refers to a module that can access the NB-IoT network. The wireless communication module plays an important role in the Internet of Things industry chain. It embodies its own value in different application scenarios. As people's needs continue to increase, the application of various industries is more abundant, and the market space is very large.
