Vodafone UK and Huawei are conducting technical trials of a new mobile technology, 4.5G (TDD+) with LTE TDD, to significantly increase the capacity and efficiency of its 4G network in urban areas, as well as lay the foundations for the introduction of 5G by 2020.

New 4 x 4 MIMO, eight-way transmit and receive (8T8R), together with multi-user beamforming are being tested in Manchester, U.K. These will support the expected rapid growth in video and virtual reality applications with the arrival of next generation smartphones.

By combining MIMO with beamforming, Vodafone is better able to focus customers’ mobile signals in specific directions to ensure the best user experience and minimize interference during peak times in highly populated areas. As a result, more signal reaches more subscribers particularly at the edge of the base station coverage, in order to provide higher average speeds across the network.

Vodafone UK’s Chief Technology Officer, Jorge Fernandes, said: “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.”

Huawei LTE TDD President, Veni Shone, 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. We are very proud of this collaboration, and are dedicated to providing optimal solutions to customers. The newly deployed LTE TDD network immediately serves the LTE TDD capable commercial smartphones and successfully carries significant live network traffic. This trial proves that LTE TDD with the most recent technologies can be naturally converged with LTE FDD and improve the overall experience enjoyed by all users on the network.”
