South Korea and the U.S. became the first countries to commercially launch the 5G Wireless Technology in April 2019. China is also moving towards launching 5G by providing commercial 5G licenses to its major carriers. Japan plans to launch 5G in time for the 2020 Tokyo summer Olympics.
The Central government in India has also set a target of 2020 for the commercial launch of 5G Wireless Technology, which is mostly in time with the other countries. The government already launched a three-year program in March 2018 to promote research in 5G. Also, Ericsson has created a 5G test base at IIT Delhi for developing applications that are tailor-made for the Indian scenario.

In a landmark study conducted on the 5G Economy by Qualcomm, it emerged that the full economic effect of 5G Wireless Technology would appear around 2035 in a broad range of industries which would produce up to $12.3 trillion worth of goods and services that were directly enabled by 5G. It also emerged that the 5G Wireless Technology could potentially generate up to $3.5 trillion in revenue in 2035 and also directly support up to 22 million jobs. Also surprising is the fact that over time, the total contribution of 5G to the Global GDP growth could be as much as the contribution of India (Which is the seventh-largest economy in the world.

The Radio Access Network mainly includes 5G Small Cells and Macro Cells that form the crux of 5G Wireless Technology as well as the systems that connect the mobile devices to the Core Network. The 5G Small Cells are located in big clusters because the millimeter wave spectrum (that 5G uses for insanely high speeds!) can only travel over short distances. These Small Cells complement the Macro Cells that are used to provide more wide-area coverage.
Macro Cells use MIMO (Multiple Inputs, Multiple Outputs) antennas which have multiple connections to send and receive large amounts of data simultaneously. This means that more users can connect to the network simultaneously.

5G Wireless Technology is now the latest cellular technology that will greatly increase the speed of wireless networks among other things(And who doesn’t want that?!!). So the data speed for wireless broadband connections using 5G would be at a maximum of around 20 Gbps. Contrasting that with the peak speed of 4G which is 60 Mbps, that’s a lot! Moreover, 5G will also provide more bandwidth and advanced antenna technology which will result in much more data transmitted over wireless systems.
