GPRS General packet radio service. GPRS enables wireless access for
mobile phones to data networks (network service). GPRS uses
packet data technology where information is sent in short
bursts of data over the mobile network. The benefit of sending
data in packets is that the network is occupied only when
sending or receiving data. As GPRS uses the network efficiently,
it allows for quick data connection setup and fast data
transmission speeds.
You must subscribe to the GPRS service. For availability and
subscription to GPRS, contact your service provider.
During a voice call, you cannot establish a GPRS connection, and
any existing GPRS connection is put on hold unless the network
supports dual transfer mode.
GPS Global positioning system. GPS is a worldwide radio navigation
system.
HSDPA High-speed downlink packet access. HSDPA brings high-speed
data delivery to 3G terminals, ensuring that users requiring
effective multimedia capabilities benefit from data rates
previously unavailable because of limitations in the radio
access network.
