General
Packet Radio Services (GPRS) is a packet -based wireless communication service that promises data rates from 56
up to 115 Kbps and continuous connection to the Internet for mobile phone and computer users. The higher data rates allow users
to take part in video conferences and interact with multimedia Web sites and similar
applications using mobile handheld devices as well as notebook computers. GPRS is based
on Global System for Mobile (GSM) communication and complements existing
services such circuit- switched cellular
phone connections and the Short Message Service (SMS).

In theory, GPRS
packet-based services cost users less than circuit-switched services since
communication channels are being used on a shared-use, as-packets-are-needed
basis rather than dedicated to only one user at a time. It is also easier to
make applications available to mobile users because the faster data rate means
that middleware currently needed to adapt applications to the slower speed of
wireless systems are no longer be needed. As GPRS has become more widely
available, along with other 2.5G and 3G services,
mobile users of virtual private networks (VPNs) have been able to access the
private network continuously over wireless rather than through a rooted dial-up
connection.
GPRS also complements Bluetooth ,
a standard for replacing wired connections between devices with wireless radio
connections. In addition to the Internet Protocol (IP), GPRS supports X.25, a packet-based protocol that is used
mainly in Europe. GPRS is an evolutionary step toward Enhanced Data GSM
Environment (EDGE) and Universal Mobile Telephone Service (UMTS).
Services offered
GPRS extends the GSM Packet
circuit switched data capabilities and makes the following services possible:
§
SMS
messaging and broadcasting
§
"Always
on" internet access
§
Multimedia
messaging service (MMS)
§
Push
to talk over cellular (PoC)
§
Instant
message and presence
§
Internet
applications for smart devices through Wireless application protocol (WAP)
§
Point
to point (P2P) service: inter-networking with the Internet (IP)
§
Point
to Multipoint (P2M) service: point-to-multipoint multicast and
point-to-multipoint group calls
If SMS over GPRS is used, an SMS transmission speed of
about 30 SMS messages per minute may be achieved. This is much faster than
using the ordinary SMS over GSM, whose SMS transmission speed is about 6 to 10
SMS messages per minute.

The 3G has the speed that the user wanted and is the latest that has been wide spread to the world today. 3G is the most common use of the people today. Good Job ^_^

ReplyDeleteit is true that the GPRS packet-based services cost users less than circuit-switched services since communication channels are being used on a shared-use, as-packets-are-needed basis rather than dedicated to only one user at a time. nice work~!
ReplyDeleteGPRS enables any existing IP or X.25 application to operate over a GSM cellular connection..
