The previous generations of mobile networks are 1G, 2G, 3G, and 4G.
First generation - 1G : 1980s: 1G delivered analog voice.
Second generation - 2G : Early 1990s: 2G introduced digital voice (e.g. CDMA- Code Division Multiple Access).
Third generation - 3G : Early 2000s: 3G brought mobile data (e.g. CDMA2000).
Fourth generation - 4G LTE : 2010s: 4G LTE ushered in the era of mobile broadband.
1G, 2G, 3G, and 4G all led to 5G, which is designed to provide more connectivity than was ever available before.
5G is a unified, more capable air interface. It has been designed with an extended capacity to enable next-generation user experiences, empower new deployment models and deliver new services.
With high speeds, superior reliability and negligible latency, 5G will expand the mobile ecosystem into new realms. 5G will impact every industry, making safer transportation, remote healthcare, precision agriculture, digitized logistics — and more — a reality.
