General Packet Radio Service (GPRS)

What is GPRS?

General Packet Radio Service (GPRS) is an extension of the GSM mobile communications standard that enabled packet-switched data transmission over mobile networks for the first time. While GSM was originally designed exclusively for voice communication, GPRS added a data path to the protocol model in which network resources are only occupied when data packets are actually being transmitted. This fundamentally distinguishes GPRS from circuit-switched connections, where a channel remains reserved for the entire duration of the connection. GPRS is therefore also referred to as 2.5G and served as a transitional technology on the path to UMTS (3G) and LTE (4G).

How does GPRS work in practice?

GPRS-capable devices share available time slots in the GSM network and can theoretically use up to eight time slots simultaneously. In real-world deployments, however, achievable transfer rates were frequently in the range of 20–50 kbit/s — sufficient for short text messages, simple status data and GPS position reports, but inadequate for larger file transfers or real-time video streaming. In transport telematics and vehicle tracking, GPRS was the preferred transmission medium for onboard units, remote tachograph readouts and mobile printing solutions in trucks for many years. GPRS-based radio data terminals also saw limited use in warehouse technology, particularly where Wi-Fi coverage was not available throughout a facility.

It is important to understand that GPRS did not require its own network infrastructure but was built on top of the existing GSM network. This significantly lowered the barrier to adoption and explains its widespread use in early telematics systems of the 2000s and 2010s.

What matters when evaluating GPRS?

For logistics and IT managers assessing or migrating existing systems, the following points are critical:

• Network shutdown: Several mobile network operators have already decommissioned their GSM and GPRS infrastructure or have plans to do so. Before deciding to continue operating GPRS-based systems, carrier support should be verified for all relevant countries of deployment.
• Bandwidth and latency: For simple position data or short status messages, GPRS may still be adequate. Applications with higher data volumes — such as real-time WMS integrations or over-the-air updates — require LTE or 5G as a minimum.
• Roaming: In international fleet operations, GPRS roaming availability varies considerably. Newer standards frequently offer more stable and cost-effective conditions.
• Hardware lifecycle: GPRS-only devices generally cannot be upgraded to LTE. New acquisitions should therefore opt for multi-standard modems (LTE Cat-M1, NB-IoT or LTE) to minimise migration investment.

Whether and for how long legacy GPRS devices can continue to operate depends heavily on the respective network operator and the country of deployment. It is advisable to address this aspect contractually and to establish a migration plan.
