GPRS (General Packet Radio Service) is the abbreviation of General Packet Radio Service technology. It is a mobile data service available to GSM mobile phone users and belongs to the data transmission technology in the second generation of mobile communications. GPRS can be said to be the continuation of GSM. It is different from the previous continuous channel transmission method. It is transmitted in packet (Packet) mode. Therefore, the cost borne by the user is calculated based on the unit of transmitted data, rather than using the entire channel. Theoretically cheaper.
The GPRS transceiver module is mainly aimed at industrial-grade applications. It is an industrial-grade communication terminal with embedded GSM/GPRS core unit. It uses the GPRS mobile communication network to build an ultra-long-distance data transmission platform for users to realize complex applications in the field of wireless data transmission.
The GPRS transceiver module can realize complex applications in the field of wireless data transmission and has been widely used in the fields of remote meter reading, industrial control, remote sensing and telemetry, and intelligent transportation. At present, the theoretical bandwidth of GPRS can reach 171Kbps. Of course, there are still problems such as transmission reliability and transmission rate in practical applications. The actual application bandwidth is around 40Kbps.
The GPRS transceiver module developed and produced by Zongheng Intelligent Control is designed with standard industrial specifications, has a complete power management system and a standard serial data interface. It has a compact appearance and simple and easy-to-use software and hardware interfaces. It can be widely used in many industrial and civil fields that require GPRS real-time data transmission.
