The channel encoding process in GPRS as well as EGPRS/EDGE consists of two steps: first, a cyclic code is used to add parity bits, which are also referred to as the Block Check Sequence, followed by coding with a possibly punctured convolutional code. [5] In GPRS, the Coding Schemes CS-1 to CS-4 specify the number of parity bits generated by ...
Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
GPRS opened in 2000 [21] as a packet-switched data service embedded in the channel-switched cellular radio network GSM. GPRS extends the reach of the fixed Internet by connecting mobile terminals worldwide. The CELLPAC [22] protocol developed 1991–1993 was the trigger point for starting in 1993 the specification of standard GPRS by ETSI SMG.

Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU , but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.

GPRS Tunnelling Protocol is the defining IP-based protocol of the GPRS core network. Primarily it is the protocol which allows end users of a GSM or WCDMA network to move from place to place while continuing to connect to the Internet as if from one location at the Gateway GPRS support node (GGSN).
