2.5G ("second-and-a-half generation") refers to 2G systems that incorporate a [[Packet switching|packet-switched]] domain alongside the existing [[Circuit switching|circuit-switched]] domain, most commonly implemented through General Packet Radio Service ([[General Packet Radio Service|GPRS]]).<ref>{{cite web |url=https://www.igi-global.com/dictionary/security-mobile-systems/26010 |title=What is Second and a Half Generation (2.5G) |website=IGI Global |access-date=2019-10-06 |archive-date=2019-10-06 |archive-url=https://web.archive.org/web/20191006162125/https://www.igi-global.com/dictionary/security-mobile-systems/26010 |url-status=live}}</ref> GPRS enables packet-based data transmission by dynamically allocating multiple timeslots to users, improving network efficiency. However, this does not inherently provide faster speeds, as similar techniques, such as timeslot bundling, are also employed in circuit-switched data services like High-Speed Circuit-Switched Data ([[HSCSD]]). Within GPRS-enabled 2G systems, the theoretical maximum [[transfer rate]] is 40 kbit/s (5 kB/s).<ref name=":1">{{cite web |url=https://www.3gpp.org/technologies/keywords-acronyms/102-gprs-edge |title=GPRS & EDGE |website=3gpp.org |access-date=2019-08-17 |archive-date=2020-04-17 |archive-url=https://web.archive.org/web/20200417193611/https://www.3gpp.org/technologies/keywords-acronyms/102-gprs-edge |url-status=live}}</ref>
