نسل دوم شبکه تلفن همراه
Sign in to save2G refers to the second generation of cellular network technology, which were rolled out globally starting in the early 1990s. The main differentiator to previous mobile telephone systems, retrospectively dubbed 1G, is that the radio signals of 2G networks are digital rather than analog, for communication between mobile devices and base stations. In addition to voice telephony, 2G also made possible the use of data services.
2G is the second generation of cellular network technology that became widespread in the early 1990s and used digital radio signals instead of the analog signals of earlier 1G systems. It mattered because the shift to digital technology enabled not only voice calls but also data services on mobile devices, expanding what phones could do.
