What is GPRS?
| Technology: | GPRS (General Packet Radio Service) |
| Purpose: | An interface overlaid on existing GSM networks to allow for Internet access |
| Frequency: | Determined by host network |
| Range: | Determined by host network |
| Speed: | Theoretical maximum speed of 171Kbps; reality is 40-50Kbps |
| Devices: | GPRS-enabled cellular phones and networks |
| Compatibility: | Does not support CDMA networks |
| General Packet Radio Service |
|
Radio technology with packet-switching protocols used in GSM networks. Considered a 2.5G technology, GPRS can support data transmission rates of between 20 kbps and 30 kbps. General Packet Radio Service: a radio technology for GSM networks that adds packet-switching protocols, shorter set-up time for ISP connections, and offer the possibility to charge by amount of data sent rather than connect time. GPRS promises to support flexible data transmission rates typically up to 20 or 30 Kbps (with a theoretical maximum of 171.2 Kbps), as well as continuous connection to the network. A 2.5G enhancement to GSM, GPRS is the most significant step towards 3G, needing similar business model, and service and network architectures. GPRS started to appear in some networks during 2000. 2.5G, EDGE, GSM, HSCSD, Packet-switching |
