An important milestone towards a 5G future

A European consortium of engineers and scientists have demonstrated what they claim is the world’s first real-world environment transmission of data in point to multipoint within part of the wireless frequency spectrum W-band, which is between 92-95GHz.

The field test, at the Universitat Politecnica de Valencia in Spain, comes after more than three years of work designing components and systems to enable the first point to multipoint wireless system above 90GHz.

The European Commission Horizon 2020 TWEETHER project, led by Professor Claudio Paoloni, Head of Lancaster University’s Department of Engineering, enabled the transmission of up to 10Gigabit per second over a large area to feed base stations for mobile networks or wireless fixed access broadband.

The system is said to offer lower cost and higher flexibility than fibre. It also enables broadband to be delivered to residential or rural areas where fibre is too expensive to be deployed, the team says.

Prof. Paoloni commented: “The development of European technology at millimetre wave aims to solve two major challenges of modern communications – a way of wirelessly transmit to and from a grid of new 5G small cells networks, and the digital divide that affects million houses without broadband in areas where the fibre cannot be deployed.

Millimetre waves are part of the frequency spectrum that is currently unused, but it is very promising, from the wide frequency bands available, to support high data rate. Challenges with wireless communication data volumes and speeds can only be met by exploiting millimetre waves and TWEETHER is addressing these technical hurdles.

This new TWEETHER millimetre wave technology, when it becomes available to mobile network providers, will be deployed as part of future 5G networks.
