5G is the fifth generation of wireless network technology. Its speed is faster and able to handle more connected devices than the other network. 5G has been launched in 2018. The history of 5G technology involved many people and companies before it was successfully deployed and widely used.

The fastest 5G network are expected to be at least 10 times faster than 4G LTE. Frequencies are above 24GHZ, reaching up to 72GHZ, which is above the extremely high frequency band’s lower boundary.

China, SouthCorea and U.S are the countries that have changed the way of life by developing 5G technology.Probably it is possible that 5G can replace Wi-Fi; there is a good chance that it would not. Both 5G and Wi-Fi can work better rather their competition.

5G has also many limitations like capacity and coverage issues. 5G will expand the mobile ecosystem into new realms, with high speed, superior reliability and negligible latency.

5G also incorporates many technologies, many of which are new, to enable it to provide the very high levels of performance required of it.


The technologies of 5G mobile communication include: Waveform modulation, multiple access, Millimeter wave communications, Massive MIMO with beam-steering and Dense networks.

5G provide many benefits but it also has some bad effects on our lives. 5G uses between 24 to 90 gigahertz frequency and then asserts that within the RF radiation portion of the electromagnetic spectrum, the higher the frequency, the more dangerous it is to living organism.
