GPRS Training

GPRS Training provides you with a comprehensive business and technical foundation in GPRS network, services and applications development.

GPRS Definitions by 3GPP

GSM™ is a circuit-switched network; ideal for the delivery of voice but with limitations for sending data. The standard for GSM was designed to evolve. In 2000 the introduction of General Packet Radio Service (GPRS) added packet-switched functionality and ‘kick started’ the delivery of the Internet on mobile handsets.

GPRS adds packet-switched functionality to GSM networks. General Packet Radio Service (GPRS) is a packet-data technology that allows GSM operators to launch wireless data services, such as e-mail and Internet access. As a result, GPRS provides operators with the ability to use data to drive additional revenue. GPRS is often called a 2.5G technology because it is a GSM operator’s first step toward third generation (3G) and a first step in wireless data services.

Based on specifications in Release 97, GPRS typically reached speeds of 40Kbps in the downlink and 14Kbps in the uplink by aggregating GSM time slots into one bearer. Enhancements in Releases R’98 and R’99 meant that GPRS could theoretically reach downlink speeds of up to 171Kbps.
The next advance in GSM radio access technology was EDGE (Enhanced Data rates for Global Evolution) or Enhanced GRPS.
With a new modulation technique yielding a three-fold increase in bit rate (8PSK replacing GMSK) and new channel coding for spectral efficiency, EDGE was successfully introduced without disrupting the frequency re-use plans of existing GSM deployments.

GPRS Training provides the attendees with an understanding of the GPRS architecture, protocols, air interface and functions involved in signaling and data transfer.

Upon attending GPRS training, you will gain an understanding of GPRS services, functionality of a GPRS network, e.g. the functions of GGSN and SGSN, the procedures of GPRS Attach, PDP-context activation, Border Gateway (BG), and GPRS QoS.
