'''2.5G''' là bước chuyển đổi từ [[công nghệ thông tin]] [[2G]] sang [[3G]]
'''2.5G''' is a stepping stone between [[2G]] and [[3G]] cellular wireless technologies. The term "second and a half generation" is used to describe 2G-systems that have implemented a packet switched domain in addition to the circuit switched domain. It does not necessarily provide faster services because bundling of timeslots is used for circuit switched data services (HSCSD) as well.

While the terms "2G" and "3G" are officially defined, "2.5G" is not. It was invented for marketing purposes only.
