Three parts make up the Internet of Things and common wireless frequency band division

Talking about the Internet of Things is undoubtedly one of the hottest topics today. From Germany's Industry 4.0, to smart transportation in the United States, to smart cities in China, the Internet of Things revolution has different applications in different countries based on different countries' different strengths and strategies.

The Internet of Things consists of three parts, the perception layer, the network layer, and the application layer. A metaphor seen on the Internet is quite an image. It can visually compare the Internet of Things system to a tree: the bottom layer is the root, the technical part. It consists of sensor technology & equipment, embedded processor technology & equipment, connection technology & equipment, and is the foundation for the survival and development of the entire tree. The degree of development of technology & equipment determines the extent of the trunk and canopy.

Sensor Technology & Equipment: Pressure Sensors, Temperature Sensors, Humidity Sensors, etc.;

Embedded Processing Technology & Equipment: Microcontroller MCU, Microprocessor MPU, Network Processor, etc.

Connection technology & equipment: NFC, Zigbee, GPS, WIFI, etc.

Above the root of the tree is the trunk, the software part. This is the trunk and central nerve of the tree. Includes device driver software, server software, and application client software.

As the carrier of the Internet of Things industry, intelligent hardware plays a vital role. A stable and mature wireless solution brings more stable products and better user experience. As a leader in the embedded industry, ZLG has been committed to the development and design of IoT wireless modules, providing the upper layer of products. A stable "root".

The common wireless frequency bands from the Internet of Things industry are as follows:

ZLG 's wireless products are widely used in industrial, medical, and consumer industries, and are known for their high stability. ZLG is also working on the development of wireless modules + MCUs in the form of core modules. The stability of the bottom layer is maximized, reducing the difficulty of secondary development of customers.

The emergence of new technologies is always generated to solve problems. Different technologies solve different problems. No technology can solve all the needs of IoT applications. The multiple wireless technologies coexisting in the Internet of Things are complementary and integrated with each other. For example, the LoRa gateway can be connected to the network via Ethernet or WiFi. BLE is superior to LoRa or ZigBee in the field of human-computer interaction.
