While the rest of us still wait to upgrade our hardware to support 4G, South Koreans will have a strong reason to laugh at the world by 2017. The country is planning to roll out 5G networks all over South Korea in the next 3 years and complete the rollout by 2020. In terms of speed, 5G blows minds! The wireless network will offer fiber-line like download speeds on your gadgets - allowing to download an 800 Mb file in just a second. Now compare that with your old-school 4G network that takes about 40 odd seconds to do that.
South Korea has been ahead of the world in terms of mobile communications. The country has operational 4G since 2010 and while the rest of the world is still to adopt it as a norm; South Korea is talking about upgrading their networks to the next generation. The government is already serious about making it all possible and has committed $1.5 billion to the rollout project. A number of local telecom companies including SK Telecom and Korea Telecom have shown keen interest in the 5G rollout and it's expected that the hardware makers like LG and Samsung will join in. Samsung has already demonstrated that 1 Gbps download speeds are possible with 5G networks.
5G networks would open a plethora of opportunities to South Koreans, allowing smooth streaming of 4K and even 8K videos over the network. It looks like South Korea might be the first country in the world to get a commercial 5G network; but other countries aren't far behind.
