In the process of gradual development and advancement in the information age, wireless communication technology has become an inevitable choice and development trend in various industries and fields of national economic construction and development. Especially for wireless data transmission operations, the importance and application value

1. Hardware design analysis of wireless data transmission terminal based on GPRS From the perspective of wireless data transmission terminal hardware design, with support, the microcontroller serial port can complete the connection with the communication module. In this process, it can not only complete the

Wireless sensor network (WSN) is a collection of small sensor nodes with sensing, computing and transmission capabilities. Since the functions of a single sensor node are limited, especially energy storage and data storage, a good network topology and routing protocol need to be developed. This

How does LoRa achieve positioning? LoRa uses Time Difference of Arrival (TDOA) to achieve geographical positioning. A technology based on LORA positioning, including an information transmission system, a network transmission system and an information processing system, characterized in that the output end of the information

The automotive field has also encountered a chip crisis in the past few days. Due to the impact of the epidemic on chip manufacturers, coupled with the STMicroelectronics strike and the shutdown of chip assembly plants in Southeast Asia and other factors, there has been

As a common long-distance wireless communication technology, LoRa is very popular because of its simple installation, low cost, and long communication distance. There are many networking methods for LoRa. Today we will talk about: “lora networking method”. Basic introduction to LoRa LoRa Networking method Based

Delivering the thinking behind technology The weather is getting colder and colder, and electric car owners in the north have begun to cross the sea again, showing off their magical powers. Everyone is thinking about how to spend the long winter in electric cars. Faced
