GPS technology is now widely used in agriculture, forestry, water conservancy, transportation, aviation, surveying and mapping, security, military, power, communications, urban management and other departments.
GPRS is the English abbreviation of General Packet Radio Service, which is translated into general wireless packet service in Chinese. Specifically, GPRS is a high-speed data processing technology, that is, it transmits data to users in the form of packets. Therefore, GPRS technology can save time, effort and cost for mobile phone to access the Internet. For example, GPRS is like ADSL of mobile communication equipment, while GSM is a common fixed telephone line. In the current domestic GPS vehicle equipment, GPRS is also used as the transmission medium of GPS data. It is so simple... At present, the domestic GPS industry equipment is divided into GSM/GPS GPRS/GPS CDMA/GPS based on the use of the network.
