GPRS could provide peak download speeds of up to 171.2 kbps. EDGE followed GPRS and increased the maximum download speed to 384 kbps. When the original GSM (Global System for Mobile Communications) networks were launched in the early 1990s, they only had the circuit-switched (CS) capability. 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).

These cellular technologies can transfer larger amounts of data than the newest NB-IoT, Sigfox and LoRaWAN technologies and differ between themselves in the speed of transmission (LTE is fastest, GPRS/GSM is slowest), power consumption (LTE ~800 mA, GPRS/GSM ~2.5 Amp peak power consumption) and network coverage (GPRS/GSM has largest coverage, LTE least coverage but growing).

They have in common: • a full-fledged QuadBand (850, 900, 1800, 1900 MHz) GSM/GPRS modem for worldwide deployment, Se hela listan på electronicsforu.com GPRS, General Packet Radio Services, är en plattform för mobila datanätverkstjänster i GSM- och 3G-nätverk.GPRS innebär att man kan överföra data till mobiltelefoner (och andra handhållna apparater) vid hastigheter mellan 30 och 100 kilobit/sekund och att telefonen kan vara ständigt uppkopplad mot Internet. GPRS implements the concept of packet switching for allowing the data services to be sent and received across the network while GSM uses circuit switching. Applications: If you are using a smartphone and want to navigate through a city, chances are that you will be using the GPS system to accurately position yourself while you find your way through the use of Google Maps.

3.GPRS is a packet data bearer and transmission service developed on the basis of the GSM system. 4.The most fundamental difference between GPRS and GSM system is that GSM is a circuit switching system, and GPRS is a packet switching system. 5.GSM can only use SMS to transmit data, and it can't be "real-time online" or "charged by volume". • Global Systems for Mobile Communications or GSM is the standard bearer of the 2G technologies. It is the most widely used technology in the world for mobile phone communications. • GPRS is an upgrade over the basic features of GSM. It allows mobile handsets to obtain much higher data speeds than what standard GSM can offer.

But how do these two receiver architectures compare? to Manufacturing Implementation and Yield : A Receiver Comparison for GSM / GPRS Applications .

Parmi les avantages de GPRS comparé au GSM  5 Mar 2021 GPRS is an up-gradation of GSM features over the basic features to obtain much higher data speeds and simple wireless access to packet data  30 Sep 2020 EDGE, or Enhanced Data GSM Evolution, is another type of 2G technology network.

However the real change in 2.5G came about in how it worked. 2G would not let you call and use data at the same time, however 2.5G would, so for the first time you could be on a call but also downloading data in the background. GPRS has more range as compare to Wi-Fi. 3G has a more extensive range as compare to Wi-Fi and GPRS.
