Digital radio, also known as wireless data radio or wireless data transmission module, is a high-performance professional data transmission radio realized with the help of DSP technology and software radio technology. Its working principle is to convert pulse signals into analog signals for transmission through a modem, and then restore the analog signals to pulse signals when receiving.
Digital radio has the characteristics of high stability, wide coverage, low power consumption, and long battery life. It can support efficient data transmission between the device end and the cloud, and provide data support for edge computing. Digital radio also has the advantages of strong anti-interference ability and good compatibility.
Digital radio is widely used in the fields of Internet of Things, satellite communication, drone communication, scientific exploration, military communication, etc. In the Internet of Things, digital radio connects a large number of devices to realize remote data interaction. In satellite communication, digital radio is used for data transmission between satellite and ground station. In drone communication, digital radio transmits information such as images, videos, and telemetry data.Digital radio, especially digital radio using RTK technology, is the core component of the automatic driving system of agricultural machinery. It ensures that agricultural machinery can be accurately positioned when operating in the field by transmitting differential positioning data in real time, providing solid technical support for precision agriculture. Digital radio plays an important role in urban water supply, gas supply monitoring and data acquisition systems. Through digital radio, the system can collect the operating parameters of water supply and gas supply equipment in real time and control the equipment to ensure the normal operation of water supply and gas supply systems.
In the future, digital radio will be more intelligent and integrated, optimizing communication parameters and predicting network conditions through built-in AI algorithms and machine learning technologies. With the popularization of 5G/6G communication technology, digital radio will support higher frequency bands and communication protocols, achieving seamless connection and efficient communication with more IoT devices. Digital radio will also strengthen security mechanisms such as data encryption and identity authentication to ensure the security and privacy of data transmission. With the continuous development of IoT technology and the expansion of application scenarios, the application prospects of digital radio will be broader.
