Samsung has announced the development of 5G mobile technology that could allow users to download an entire film in a second.
The South Korean firm has successfully tested "ultra-high speed" fifth-generation equipment, which it hopes will transmit data several hundred times faster than existing 4G networks.
It claims subscribers could use the technology to download high-quality digital films "practically without limitation" and watch 3D movies or stream high-definition programmes in real-time.
Samsung believes its new transceiver is the world's first device capable of providing "ubiquitous" 5G broadband and hopes to bring the service to customers by 2020.
It announced the development after conducting a test where data was transmitted at speeds of more than one gigabit per second over a distance of up to 2km.
Customers using 4G services – currently provided in the UK by EE – access average speeds of between eight and 12 megabits per second (Mbps).
"The new technology sits at the core of 5G mobile communications system and will provide data transmission up to several hundred times faster than current 4G networks," Samsung said in a blog post.
The company believes the equipment could provide a solution to recent surges in wireless Internet usage.
It added: "Samsung's new technology will allow users to transmit massive data files including high-quality digital movies practically without limitation.
"As a result, subscribers will be able to enjoy a wide range of services such as 3D movies and games, real-time streaming of ultra high-definition content, and remote medical services."
In the blog post, Samsung claims its technology uses high-frequency wavebands, which were previously deemed unsuitable for mobile networks.
It said: "The implementation of a high-speed 5G cellular network requires a broadband of frequencies, much like an increased water flow requires a wider pipe.
"While it was a recognised option, it has been long believed that the millimetre-wave bands had limitations in transmitting data over long distances due to its unfavourable propagation characteristics.
"However, Samsung's new adaptive array transceiver technology has proved itself as a successful solution. It transmits data in the millimetre-wave band at a frequency of 28 GHz at a speed of up to 1.056 Gbps to a distance of up to two kilometers [sic]."
