Vodafone, Huawei team up for 4.5G trials

Vodafone UK and Huawei Wednesday partnered to initiate 4.5G (TDD+) with LTE TDD trials to increase the capacity and efficiency of their 4G network in urban areas and step closer to the introduction of 5G by 2020.

New Multiple-Input Multiple-Output techniques eight-way transmit and receive (8T8R), together with multi-user beam forming are being tested in Manchester, Chinese gear maker Huawei said in a statement.

These, according to it, will support the expected rapid growth in video and virtual reality applications with the arrival of next generation smartphones.

Beam forming and four-way receiver diversity significantly improve performance in heavily built up areas, by combining the signals from multiple angles and co-located antennas in order to reduce interference and improve throughput.

The trial involves 4×4 versions of MIMO in order to deliver mobile data services at much greater speeds and with improved accuracy, the company added. “We are working hard with our radio network equipment partners to ensure our network is future-proofed for the expected arrival of 5G in four to five years’ time, whilst continually improving our 4G performance for customers throughout the UK,” Vodafone UK’s Chief Technology Officer, Jorge Fernandes said.

“This joint innovation with Vodafone has proved that 4.5G (TDD+) is a good solution to release the potential of TDD spectrum and will help Vodafone build the most advanced LTE network available,” said Huawei LTE TDD President, Veni Shone.
