Simply put, GPRS is a high-speed data processing technology that transmits data in the form of \"packets\". Network capacity is only allocated when needed and released when not needed. This transmission method is called statistical multiplexing. At present, the transmission speed of GPRS mobile communication network can reach 115k/s. GPRS is a technology developed on the basis of GSM. It is a technology between the second-generation digital communication and the third-generation packet-based mobile service, so it is usually called 2.5G. WAP (Wireless Application Protocol: Wireles…
