The rollout of the 4G mobile phone network is not yet complete, however Samsung have already claimed that its new 5G technology could offer “ubiquitous” access to ultra-high-speed networks. These are claimed to operate at 100 times the speed of current connections and offer regular gigabit access.
In a blog post, Samsung said that 5G networks could allow “a wide range of services such as 3D movies and games, real-time streaming of ultra-high-definition content, and remote medical services”.
Whilst research into 5G has been taking place in laboratories around the world for some time, the ‘mmWave Mobile Technology’ is the first system that claims to be fully fledged. Last year, the University of Surrey announced £35m funding for a research centre supported by Huawei, Samsung, Fujitsu, Telefonica and others.
Scientists had previously believed that high-frequency wavebands were generally not suitable for long-range communications required by mobile networks. Samsung said “the implementation of a high-speed 5G cellular network requires a broad band of frequencies; much like an increased water flow requires a wider pipe. While it was a recognized 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.”
Current 4G networks in the UK use bands as low as 800MHz, but Samsung’s new research has concentrated on much higher frequencies. The company claims it has worked over distances up to 2km.
“Our new adaptive array transceiver technology has proved itself as a successful solution,” the company claims. “It transmits data in the millimetre-wave band at a frequency of 28 GHz at a speed of up to 1.056 GB per second up to a distance of two kilometres. The adaptive array transceiver technology, using 64 antenna elements, can be a viable solution for overcoming the radio propagation loss at millimetre-wave bands, much higher than the conventional frequency bands ranging from several hundred MHz to several GHz.”
It is anticipated that a 5G network will not be commercially available until after 2020, although Samsung is allegedly aiming to have commercialised 5G by then. This focus on mobile infrastructure technology could mark a new plan to challenge the dominance of companies such as Huawei in this area.
“Samsung’s latest innovation is expected to invigorate research into 5G cellular communications across the world,” Samsung claimed. “We believe it will trigger the creation of international alliances and the timely commercialization of related mobile broadband services”.
