Samsung Electronics has successfully transmitted data over a 28GHz 5G network at a speed of 7.5Gbps in a stationary environment, achieving a speed record using the future mobile standard.
At the same time it has also managed to achieve an uninterrupted, stable connection of 1.2Gbps in a vehicle travelling at 100km/h.
The test results mean Samsung can now transmit data more than seven times faster than it could 18 months ago, when it hit 1Gbps over a 28GHz 5G network.
The result is significant as it also marks the first successful outdoor 5G test – previously all 5G testing had been conducted in stable lab environments with a minimum of outside influences.
The use of the 28GHz frequency is also noteworthy, Samsung explained, because previously the industry has shied away from higher frequencies as their range is generally shorter than lower bands.
Samsung deployed its own Hybrid Adaptive Array Technology to overcome this drawback. This uses millimetre-wave frequency bands to enable high-frequency transmission over longer distance.
More on 5G networks
Head of digital media communications at Samsung's research and development centre Chang Yeong Kim said the company will continue to develop technologies that contribute to the 5G standard.
“Whether you are talking about mobile devices, the cloud, or the internet of things, the demand for 5G telecommunications standards and its supporting technologies will continue to grow,” he said.
5G networks will continue to get faster as the standard is improved upon and refined before commercial availability sometime next decade, possibly sooner in advanced markets such as South Korea.
The current maximum speed available in the UK over a 4G network is 60Mbps on EE, but it is in the process of deploying a 300Mbps network using technology known as carrier aggregation, which rival Vodafone has also just begun to roll out.
Also known as Long Term Evolution (LTE) Advanced or 4.5G, the technology allows Vodafone to leverage both its portfolio of low frequency 800MHz and higher frequency 2.6GHz spectrum bands to offer better average speeds to simultaneous users.
It said the lower frequency component would offer better service indoors, and the higher frequency component ensures greater peak speeds and network capacity.
Like EE, Vodafone’s top speeds currently top out at around 60Mbps, and the operator claimed carrier aggregation would allow it to go up to three times faster than that.
It is making LTE Advanced available in October 2014 in Birmingham, London and Manchester, and plans to roll out in other cities by Christmas 2014.
