1G Launched by Nippon Telegraph and Telephone in 1979 , 1G wireless technology was first introduced to the citizens of Tokyo, Japan. It was an analog system and offered no data capabilities, but by 1984, the network covered all of Japan, making it the first country to have 1G service nationwide.

The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit) . These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently.
Read moreWhat was the first 1G phone?
In 1983, the first 1G network launched in the USA was Chicago-based Ameritech using the Motorola DynaTAC mobile phone. Several countries then followed in the early to mid-1980s including the UK, Mexico and Canada.
Read moreWhat is the frequency of 1G?
Early cellular networks, including 1G, operated at a frequency of 850 MHz and 1900 MHz . Then, 2G and 3G networks operated at additional frequency bands and spectrum around 2100 MHz, and 4G LTE technology operated at additional frequency bands and spectrum around 600 MHz, 700 MHz, 1.7/2.1 GHz, 2.3 GHz, and 2.5 GHz.
Read moreWhat is the frequency of 5G?
High-band 5G uses frequencies of 24–47 GHz , near the bottom of the millimeter wave band, although higher frequencies may be used in the future. It often achieves download speeds in the gigabit-per-second (Gbit/s) range, comparable to cable internet.
Read moreWhat is difference between 3G 4G and 5G?
4G is more spectrally efficient than 3G, just as 5G is more spectrally efficient than 4G . Each generation delivers more data per hertz than the previous one. 3G works at frequencies up to 2.1Gigahertz, 4G up to 2.5Gigahertz and 5G can be up to 95 Gigahertz. That is why there is a lot of hype around 5G.
Read moreIs 5G faster than 1G?
5G is shorthand for fifth generation, and it promises cellphone speeds as much as 100 times faster than the norm today, 4G LTE . Gigabit internet (so named because data are transmitted at up to 1 gigabit or 1,000 megabits per second) also promises that kind of speed — about double that of the fastest cable internet.
