Wireless radio frequency technology refers to the use of 30 ~ 3000MHz (the definition of the frequency range may be different) electromagnetic waves to achieve information and energy transmission technology in general. From the field of application, wireless radio frequency technology is mainly used for information transmission, such as the current mobile communication (cell phone), wireless Internet (WiFi), radar and so on. As an energy application, the most common is for heating (e.g., household microwave ovens). In addition, RF power sources are also used in high-energy physics gas pedals and medical equipment (e.g. nuclear magnetic **** vibration).
Radio frequency tag (RFID) technology belongs to a specific application of radio frequency technology, is the use of radio frequency electromagnetic waves to achieve a certain distance, contactless information recognition technology. In addition to the radio frequency technology covered by the transmission, reception, modulation, demodulation and other traditional technical means, the challenge of RFID technology is to achieve low-cost, small size, low-power conditions for the storage of information as well as the corresponding wireless communication functions.
The application of RFID technology also requires the corresponding software middleware and business model support. The application of the Internet of Things is one of the most optimized application prospects.
