	GPRS - General Packet Radio Service
		General Packet Radio Service: A GSM data transmission technique that does not set up a continuous channel from a portable terminal for the transmission and reception of data, but transmits and receives data in packets.
		General Packet Radio Services: is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users.
		General Packet Radio Services is an ETSI standard and is the first implementation of a packet switched wireless protocol, is that GPRS only uses the network when data is to be sent.

		General Packet Radio Service (GPRS) is a mobile data service available to users of GSM mobile phones.
		It is often described as "2.5G", that is, a technology between the second (2G) and third (3G) generations of mobile telephony.
		A radio noise induced pause can be interpreted by TCP as packet loss, and cause a temporary throttling in transmission speed.

	General Packet Radio Service GPRS , SGSN, GGSN, Path to UMTS
		GPRS (General Packet Radio Service) is a packet data communications system integrated with the GSM cellular telephone system.
		GPRS is a packet-based wireless communication service that, promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users GPRS is based on "regular" GSM (with the same modulation) and will complement existing services such circuit-switched cellular phone connections such as SMS or cell broadcast.
		In theory, GPRS packet-based service should 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 only to one user at a time.

	Introduction to GPRS, the General Packet Radio Service
		Packet switching is similar to a jigsaw puzzle - the image that the puzzle represents is divided into pieces at the manufacturing factory and put into a plastic bag.
		Packet switching means that GPRS radio resources are used only when users are actually sending or receiving data.
		In the case of mailbox email services, the emails are actually stored and the user gets a notification on their mobile phone and can then retrieve the full email by dialing in to collect it, forward it and so on.

	Emerging Technology: Clear Signals for General Packet Radio Service
		Packet service lets users maintain extended virtual connections, but only be billed when they actually communicate data.
		Theoretically, a user could have all eight time slots in the radio channel, but carriers are likely to limit the number of download slots to four (or fewer), for a maximum of 52Kbits/sec, and the number of slots available for uploads to one, for a maximum of 13Kbits/sec.
		EDGE is a new radio interface that employs a combination of new coding schemes, new modulation, and the ability to dynamically choose the best possible combination of coding scheme and modulation, based on instantaneous error rates.

	GPRS - General Packet Radio Service (Site not responding. Last check: 2007-10-20)
		GPRS is defined by 3GPP (Third Generation Partnership Project) and is employed to connect mobile cellular users to PDN (Public Data Network).
		Within the GSM network it shares the network databases and radio access network and employees functions known as the PCU (Packet Control Unit), SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node) to provide packet switching data services across the fixed and radio network.
		Billing for GPRS services will initially be based on volumes, but as services develop it is likely that URL billing from outside the GPRS network will be employed.

	Paper: GPRS
		A number of wireless data services are available today, but none are as exciting as a forthcoming data service for GSM networks called General Packet Radio Service (GPRS).
		IP packets from the Internet addressed for the mobile station are received by the GGSN, forwarded to the SGSN and then transmitted to the mobile station.
		This radio channel carries a raw digital radio stream of 271 kbps which for voice calls is divided into 8 separate data streams, each carrying about 34 kbps.

		In general, there is a many-to-many relationship between the SGSNs and the GGSNs: A GGSN is the interface to external packet data networks for several SGSNs; an SGSN may route its packets over different GGSNs to reach different packet data networks.
		The billing of the service is then based on the transmitted data volume, the type of service, and the chosen QoS profile.
		The GGSN decapsulates the packets and sends them out on the IP network, where IP routing mechanisms are used to transfer the packets to the access router of the destination network.

	General Packet Radio Service - Wikipedia, the free encyclopedia
		Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time.
		During its heyday, the mid 2000's, typical rates for GPRS service varied wildly, ranging from EUR €1 per megabyte to over €20 per megabyte.
		The maximum speed of a GPRS connection (as offered in 2003) is the same as modem connection in an analog wire telephone network, about 4–5 kB/s (depending on the phone used).
