Cosmote Greece, Huawei successfully trial ‘Super Dual Band’ backhaul

8 Mar 2016

Greece’s largest mobile operator by subscribers Cosmote and Chinese technology giant Huawei have announced the successful completion of field trials of a new multi-gigabyte microwave backhaul solution named ‘Super Dual Band’ which began in January. Huawei notes in a press release that the demand for such a solution is driven by accelerating mobile broadband usage, as existing microwave-based mobile backhaul networks struggle to meet the need for multi-gigabyte bandwidth at long distances. Multi-gigabyte throughput links often require multiple hardware components, large antennas, and high spectrum resources in congested frequency bands, impacting significantly operators’ total network operating costs. Huawei’s Super Dual Band solution aggregates the traditional frequency (6GHz-42GHz) together with E-band (71GHz-86GHz), combining the long-distance benefits of the former with the large capacity advantage of the latter, ensuring efficient multi-gigabyte transmission for links exceeding 7km.

Bob Chen, president of Huawei’s microwave product line, said: ‘Deutsche Telekom [Cosmote’s group parent] and Huawei will jointly focus on potential microwave innovation technology looking forward to LTE-Evo and even 5G.’
