GPRS, or General Packet Radio Service technology 行動上網技術

GPRS technology is "always on-line and always connected" meaning that there are no special dial-ups required. GPRS users can remain on-line without continuously occupying a specific radio channel since a channel is allocated only when a data packet is to be sent or received. This means users will not have to log on each time they want to check their e-mail or use other services. Consequently, operators may encourage GPRS users to remain connected by charging them for data volume instead of connection time. GPRS will enable increase data transmission speeds from the current 9.6 kbps to over 50 kbps. Additionally, GPRS is just one step on the migration to EDGE and 3G, where speeds will approach 384 kbps and 1.5 mbps. GPRS is also a global standard and has the support of all telecom vendors, which means that your interoperability concerns are greatly reduced.
