South Korea launched the world’s first nationwide 5G mobile networks on 11 pm April 3, 2019. Three top telecom providers SK Telecom, KT, and LG Uplus launched the 5G services.
South Korea launched the 5G services two days ahead of the schedule as there were speculations that US mobile carrier Verizon might start its 5G services early. Verizon began rolling out its 5G services in Chicago and Minneapolis on April 3, a week ahead of schedule. Reports suggest the 5G network in South Korea was launched in South Korea two hours ahead of the US.
Benefits of 5G
5G will provide smartphones with near-instantaneous connectivity, 20 times faster than 4G. This allows users to download entire movies in less than a second.
5G will deliver vastly increased capacity, lower latency, and faster speeds. 5G networks will operate in a high-frequency band between 28 GHz and 60 GHz. This range is known as the millimeter wave (mmWave) spectrum and the sub-6 GHz range that LTE calls home will also be used. As a result, a lot of bandwidth will be available to users.
In addition to greater bandwidth, the new 5G networks will have a dense, distributed network of base stations in the small cell infrastructure. This will allow more processing to happen on the edge, leading to lower latencies.
The 5G technology is crucial for the future development of devices such as self-driving vehicles and is expected to bring about $565 billion in global economic benefits by 2034.
