The science ministry said it aims to implement the technology – about 1,000 times faster than the 4G services currently available – within six years.
"We helped fuel national growth with 2G services in the 1990s, 3G in the 2000s and 4G around 2010. Now it is time to take preemptive action to develop 5G," the ministry said in a statement.
Under the roadmap, a trial 5G service will be rolled out in 2017 and a fully commercial service in
Priority will be given to developing key features for the new network, including Ultra-HD and hologram transmission as well as cutting-edge social networking services.
Related industries will be able to rack up sales of 5G-related devices and infrastructure equipment worth KWD $331tn from 2020 to 2026, the ministry estimated.
The government hopes to implement the plan with investment and cooperation from operators such as
It also aims to expand the telecom infrastructure equipment industry, which is relatively weaker than the mighty mobile device sector.
Led by Samsung – the world's top handset maker –
"But the [telecom] infrastructure equipment industry has only a 4.4% share in the global market, with exports very limited," the ministry said.

5G technology will allow users to download a 800-megabyte movie file in one second, compared with 40 seconds using 4G, the science ministry said, adding that such speeds would help South Korean firms win overseas deals.
Officials said the new service would also mean people on bullet trains running faster than 500 kilometres (310 miles) an hour would even be able to access the Internet, compared with 300 kph currently.
"Bullet trains around the world keep getting faster, with some in
"If we have the technology to allow fast Internet access in these trains, it can open new opportunities for us globally," he said.
Samsung said it had found a way to harness millimetre-wave bands which have proved to be a sticking point for the mobile industry to date.
The test used 64 antenna elements, which the tech titan said overcame the issue of "unfavourable propagation characteristics" that have prevented data travelling across long distances using the bands.
However, it made clear that the technology would not be available commercially before the end of the decade.
