GPRS, or General Packet Radio Service,  was a notable advancement in mobile data services within the context of 2.5G technology. It emerged as an improvement over traditional circuit-switched data services utilised in 2G networks. Unlike its predecessor, GPRS relies on packet-switching technology, breaking down data into packets for more efficient transmission over the network. This departure from circuit-switched systems, primarily designed for voice calls, marked a shift towards enhanced data handling.

An essential characteristic of GPRS is its provision of an “always-on” connectivity feature. This means that users can maintain a persistent connection to the internet or other data services without the need to establish a new connection for each session. This continuous connectivity represents a departure from the on-demand nature of earlier data services, offering greater convenience for users engaging in various online activities.

In terms of data speeds, GPRS represents a moderate improvement over traditional 2G technologies. While it is faster than its predecessor, with typical speeds ranging from 56 to 114 kbps (kilobits per second), it still falls short of the higher data speeds associated with later generations like 3G and 4G.

Crucially, GPRS is designed to be backward compatible with existing 2G networks, ensuring a smooth transition and coexistence of both voice and data services. This compatibility facilitated the integration of GPRS into mobile networks without disrupting the established communication infrastructure.

GPRS played a pivotal role in the early development of mobile data applications. It laid the foundation for various functionalities, including basic web browsing, email services, and the emergence of simple mobile applications. Although not widely used today, GPRS’s legacy is evident in the technological progression towards faster, more efficient, and more versatile mobile data communication technologies.
