There are mainly 5 Technologies used in 5G
1. Speeds and Feeds
2.Utilizing the unlicenced spectrum
3.IOT devices
4.Virtualization:NFV & SDN
5.New radio
Explanation :
1. Speeds and Feeds:
          Â
The speed increased in 5G by using higher modulation scheme such as
256 QAM. Due to this QAM technic 5G will achive 3 GBPS without
overhauling radio technologies.
2.Utilizing the unlicenced spectrum:
          Â
To achieve higher thoughput requirements, the licensed carrier
spectrum is not enough.
- Â Â Usage of polar codes such as LDPC for error
correction
- 4X4 MIMO(multi input multi output) to increase throughput and
work with more users simultaneously
    3. IOT devices:
               Â
