GPRS or better known as General Packet Radio Service is the world's most preferred wireless data service, available now with almost every GSM network. GPRS is a connectivity solution based on Internet Protocols that supports a wide range of enterprise and consumer applications. With throughput rates of up to 40 kbit/s, users have a similar access speed to a dial-up modem, but with the convenience of being able to connect from anywhere. GPRS customers enjoy advanced, feature-rich
data services such as color Internet browsing, e-mail on the move, powerful visual communications such as video streaming, multimedia messages and location-based services.

There are 3 classes of GPRS device being developed, of which only class B is currently available: -
Class A - Operates in GSM and GPRS modes at the same time, and hold simultaneous voice and data sessions.
Class B - Operates in GSM and GPRS modes at the same time, and but cannot hold simultaneous calls.
Class C - Can be active in either GSM or GPRS mode, but not at the same time
For operators, the adoption of GPRS is a fast and cost-effective strategy that not only supports the real first wave of mobile Internet services, but also represents a big step towards 3GSM or wide band-CDMA networks and services. GPRS is capable enough to support a wide range of bandwidths. It provides an efficient use of limited bandwidth and is particularly suited for sending and receiving small bursts of data, such as e-mail and Web browsing, as well as large volumes of data. GPRS can be
used for services such as Wireless Application Protocol (WAP) access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web access
GPRS or General Packet Radio Service network is an "always on", private network for data. It uses the existing GSM network to transmit and receive TCP/IP based data to and from GPRS mobile devices. Private IP addresses are typically dynamically assigned within the network to mobile devices. However, Access Point Names (APN's) provide a gateway route to other networks such as the Internet, WAP services or private corporate networks. Firewalls typically reside at the APN to isolate the public
and private networks. IP addresses allocated to mobile GPRS devices are therefore not addressable from outside the GPRS network , for example from the Internet without specialized services or infrastructure.
Some of the benefits of GPRS are as follows :
Efficient - GPRS mobile devices only use the GSM network when data is transferred. The GSM connection is not dedicated to each user, therefore it can be shared with many users resulting in efficient use of the network.
Fast - GPRS gives speeds of up to 5 time faster than GSM. GPRS offers maximum data rates of 56Kbps (down) and 14.4kbps (up),
however this is shared bandwidth therefore actual data rates are potentially lower.
Payment based on data usage - Billing is not based on time, but on the amount of data actually transferred.
There are a number of GPRS devices, each of which can offer GSM services too, such as voice calls and SMS.
- A GPRS Mobile Phone
- A GPRS Radio Card for a PC
- A Hand held PC with an in-built GPRS Mobile
- A remote machine enabled with a Comtech GPRS M2M device.
Lastly GPRS provides new business opportunities in making the Internet accessible from a mobile phone. It is a vital step on the road to an always-connected ubiquitous Mobile Internet as announced by 3G networks. Ideally a service based charging model, such as instituted by Blackberry, where a user pays a fixed charge for a specific service such as email or web access, is needed for end user acceptance of GPRS. The technology of GPRS is used for SMS on mobile and helps to send Instant Message which is an easy way to organize a quick online conference when it is not possible to have a telephone conference.
