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

Introduction: LoRa devices and wireless radio frequency technology are a long-distance, low-power IoT solution that has been widely adopted in recent years. This technology supports telecommunications companies, IoT application developers and system integrators to deploy low-cost and interoperable devices around the world. IoT networks, gateways,

There are two types of wireless data transmission terminals or wireless acquisition systems. The first is used in online laboratories, and the second is equipped with building video surveillance systems in buildings. The first is to use smart grids to build wireless data transmission terminals,

The outstanding features of LoRa technology in terms of high performance, long distance, low power consumption, and support for large-scale networking, ranging and positioning make this solution (terminal LoRa base station) an ideal technology for the large-scale promotion and application of the Internet of Things.

1. Product introduction of plc wireless transmission module GPRS communication is based on the existing communication network of mobile operators and is mainly used for data transmission. The purpose of Zongheng Intelligent Control’s development of PLC wireless communication control module is to enable people who

LoRa technology was originally a spread spectrum wireless modulation patented technology developed by a French company, Cycleo. After it was acquired by the American Semtech company in 2012, Semtech conducted strong marketing of the technology. In order to introduce other companies, including some mobile operators,

Microcontrollers were produced with the development of electronic computers (computers). With the development of society and the improvement of needs, computers are constantly updated and developed. Since computers were born in response to numerical calculations, electronic computer technology has long been developed to meet the
