What is spectrum 2G and 3G?

Radio spectrum refers to a range of radio frequencies. The bandwidth of a radio signal is the difference between the upper and lower frequencies of the signal. The amount of bandwidth needed for 3G services could be as much as 15-20 Mhz, whereas for 2G services a bandwidth of 30-200 KHz is used.

What is 1G 2G 3G 4G and 5G?

1G, 2G, 3G, 4G and 5G represent the five generations of mobile networks where G stands for ‘Generation’ and the numbers 1, 2, 3, 4 and 5 represent the generation number. Since the early 1980s, we see a new generation of mobile networks almost every ten years.

Are 2G networks going away?

Cellular networks are changing, and 2G and 3G networks are sunsetting. In order to provide a faster, more responsive network to their customers, they must re-use the spectrum with newer, more efficient cellular technology. Old 2G/3G infrastructure makes way for new networks, and older cellular devices must be retired.
