GPRS Connection
3.3.1
Overview
GPRS is a packet-switched technology, enabling multiple users to share the same transmission channel. In addition,
GPRS will transmit when there is outgoing data. This means that the available bandwidth can be dedicated solely to
data communication when needed. In general, a GPRS network can be seen as a special IP network offering IP
connectivity to IP terminals. Devices such as PCs, embedded computers, and PLCs that are PPP-enabled can be easily
connected to the IP network and the Internet.
