General Packet Radio Services
The introduction of GPRS (General Packet Radio
Services) is one of the key steps in the evolution of
today’s GSM networks for enhancing the capabili
-
ties of data communication. Data traffic is increas-
ing enormously (over both wired and wireless
networks), with the growth in demand for Internet
access and services paralleling that for mobile
communications. Users want access to the Internet
while they are away from their offices and homes,
and surveys have found that the vast majority of
business professionals want the ability to send and
receive email, browse the Web and transmit text
and graphics on a portable device. That is why the
main applications driving Mobile Internet develop
-
ment are email clients and Web browsers.
The demand for high-speed Internet access will be
the key driver for coming generations of wireless
services, and GPRS can deliver the necessary
speed. GPRS allows innovative services to be cre
-
ated, enabling new and previously inaccessible
market segments to be addressed and increasing
customer loyalty.
GPRS applications can be developed as both hori-
zontal and vertical applications. Vertical applica-
tions are specific, including those for operations
such as reaching police and emergency, taxi, deliv
-
ery or automated services (vending machines,
supervision, vehicle tracking). Horizontal applica
-
tions are more generic and include those for Inter-
net access, email, messaging, e-commerce and
entertainment.
GPRS is able to take advantage of the global cov-
erage of existing GSM networks. Applications
developed for GPRS can be deployed on a large
scale and can reap the associated benefits. GPRS
also provides a secure medium for connections to
private networks, banking and financial services.
With GPRS, the T290i/T290c sends data in “pack-
ets” at a very high speed. The T290i/T290c remains
connected to the network at all times, using trans
-
mission capacity only when data are sent or
received. For details, see
“GPRS technical data” on
