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.
