Fifth Generation (5G)


                  5G refers to the fifth generation of cellular service launched in 2016. It is based on OFDM (Orthogonal
                  frequency-division multiplexing). 5G technology is  meant to deliver high speeds, superior reliability,
                  negligible latency, and improved efficiency.
                  Transmission speed in 5G is around five hundred times faster than 4G. 5G provides more features than 4G
                  with data transfer speed upto 20 Gbps. 5G can be used in services like extreme reality (XR), instant cloud
                  access, virtual reality (VR) and entertainment.

                  5G has been introduced in more than 50+ countries and counting. The first country to adopt 5G was
                  South Korea in 2019.
