5G network is a new technology that has attracted much attention in recent times. With the gradual rollout of 5G networks, 5G networks will get closer and closer to us. For a long time, the industry has generally described 5G networks with high speed, low latency, and large capacity. What are the characteristics of 5G? Today we will take a look at the characteristics and applications of 5G network···

LoRa is a kind of LPWAN communication technology, providing users with a simple system that can realize long-distance, long battery life, and large capacity, and then expand the sensor network. At present, LoRa mainly operates in free frequency bands around the world, including 433, 868, 915 MHz and so on. So what is the application of LoRa base station?

The full name of DTU is a wireless data terminal of the Internet of Things, which uses the public carrier network to provide users with wireless long-distance data transmission. It adopts high-performance industrial-grade 8/16/32-bit communication processors and industrial-grade wireless modules, With embedded real-time operating system as the software support platform, it also provides RS232 and ···

5G can play its own powerful role through many applications of the Internet of Things: smart agriculture, smart logistics, smart home, car networking, smart city, etc.

5G refers to the fifth-generation mobile phone mobile communication standard, also known as the fifth-generation communication technology. Compared with 4G networks, 5G has more powerful communication and bandwidth capabilities, which can meet the requirements of high-speed stability and wide coverage of IoT applications.

The main function of DTU is to wirelessly transmit data from remote devices back to the back-end center. To complete data transmission, a complete data transmission system needs to be established. GPRS DTU is a wireless data terminal for the Internet of Things, which uses the public operator's network GPRS network (also known as G network) to provide users with wireless long-distance data transmis···

The main differences between LoRaWAN and 3GPP:Another major difference between LoRaWAN and 3GPP is the use of unlicensed spectrum. LoRaWAN allows easy deployment of "campus" networks (smart cities, smart buildings, smart airports, smart factories) with thousands of devices in a small area. The corporate network can be completely under the control of the customer, and the data is still encrypted en···

Many people confuse the two concepts of LoRaWAN and LoRa. In fact, LoRaWAN refers to the networking protocol of the MAC layer. And LoRa is just a physical layer protocol. Although the existing LoRaWAN networking basically uses LoRa as the physical layer, the LoRaWAN protocol also lists that GFSK can also be used as the physical layer in some frequency bands.

IoT gateway can integrate the data collected by different terminals and transmit it to the next level to complete the transmission of information between each level. The IoT gateway can realize the protocol conversion between perception networks and communication networks, as well as between different types of perception networks; it can realize both wide area network communication and local area ···

MQTT and Modbus can complement each other to improve the performance of the Internet of Things. Using Modbus as a local interface to manage devices, and using MQTT as a global protocol to expand the range of devices, both have played an important role.
