South Korea is planning to roll out a 5G wireless service, the country’s government claims.

It has revealed plans to invest $1.5bn into the endeavour, which they claim would allow downloading full-length films within a second, according to the country’s science ministry.

Aimed to be made available by the end of the decade, the move would require consumers to buy devices that support 5G networks.

"We helped fuel national growth with 2G services in the 1990s, 3G in the 2000s and 4G around 2010," the ministry said.

"Now it is time to take pre-emptive action to develop 5G.

"Countries in Europe, China and the US are making aggressive efforts to develop 5G technology … and we believe there will be fierce competition in this market in a few years."

Recently, South Korea’s SK Telecom revealed plans to launch a new 300Mbps wireless broadband service, which is four times faster than to its existing standard 75mbps LTE mobile broadband.

The company will use its latest "LTE-Advanced 3 Band Carrier Aggregation (CA)" which incorporates 20MHz and two 10MHz bands together and doubles the standard LTE-A speed of 150Mbps.
