AI overview
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.
