General Packet Radio Service (GPRS) o servicio general de paquetes vía radio creado en la decada de los 80 es una extensión del Sistema Global para Comunicaciones Móviles (Global System for Mobile Communications o GSM) para la transmisión de datos mediante conmutación de paquetes. Existe un servicio similar para los teléfonos móviles, el sistema IS-136. Permite velocidades de transferencia de 56 a 144 kbps.
Una conexión GPRS está establecida por la referencia a su nombre del punto de acceso (APN). Con GPRS se pueden utilizar servicios como Wireless Application Protocol (WAP) , servicio de mensajes cortos (SMS), servicio de mensajería multimedia (MMS), Internet y para los servicios de comunicación, como el correo electrónico y la World Wide Web (WWW).Para fijar una conexión de GPRS para un módem inalámbrico, un usuario debe especificar un APN, opcionalmente un nombre y contraseña de usuario, y muy raramente una dirección IP, todo proporcionado por el operador de red. La transferencia de datos de GPRS se cobra por volumen de información transmitida (en kilo o megabytes), mientras que la comunicación de datos a través de conmutación de circuitos tradicionales se factura por minuto de tiempo de conexión, independientemente de si el usuario utiliza toda la capacidad del canal o está en un estado de inactividad. Por este motivo, se considera más adecuada la conexión conmutada para servicios como la voz que requieren un ancho de banda constante durante la transmisión, mientras que los servicios de paquetes como GPRS se orientan al tráfico de datos. La tecnología GPRS como bien lo indica su nombre es un servicio (Service) orientado a radio enlaces (Radio) que da mejor rendimiento a la conmutación de paquetes (Packet) en dichos radio enlaces.

General packet radio service (GPRS)
GPRS (General Packet Radio Service) is a very widely-deployed wireless data service, available now with most GSM networks.
GPRS offers throughput rates of up to 40 kbps, enabling mobile handsets to access online services at a similar speed to a dial-up modem, but with the convenience of being able to connect from almost anywhere.
GPRS enables people to enjoy advanced, feature-rich data services, such as e-mail on the move, multimedia messages, social networking and location-based services.
General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and 3G cellular communication system’s global system for mobile communications (GSM). GPRS was originally standardized by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP).[1][2]
GPRS usage is typically charged based on volume of data transferred, contrasting with circuit switched data, which is usually billed per minute of connection time. 5 GB per month for a fixed fee or on a pay-as-you-use basis. Usage above the bundle cap is either charged per megabyte or disallowed.
GPRS is a best-effort service, implying variable throughput and latency that depend on the number of other users sharing the service concurrently, as opposed to circuit switching, where a certain quality of service (QoS) is guaranteed during the connection. In 2G systems, GPRS provides data rates of 56–114 kbit/second.[3] 2G cellular technology combined with GPRS is sometimes described as 2.5G, that is, a technology between the second (2G) and third (3G) generations of mobile telephony.[4] It provides moderate-speed data transfer, by using unused time division multiple access (TDMA) channels in, for example, the GSM system. GPRS is integrated into GSM Release 97 and newer releases.
