Huawei and Cosmote completes pilot of multi-giga backhauling

Chinese technology company Huawei and Greece largest mobile operator by subscribers Cosmote, a member of OTE group, say they have successfully completed field trials of innovative multi-gigabyte microwave backhaul solution called ‘Super Dual Band’ which they began in January.

Huawei in its press release noted that microwave transmission, a key solution on mobile backhaul networks throughout the years, struggles to meet the need for multi-Giga bandwidth at long distances.

Wireless backhaul is the wireless communication and network infrastructure responsible for transporting communication data from end users or nodes to the central network or infrastructure and vice versa. It is the intermediate wireless communication infrastructure that connects smaller networks with the backbone or the primary network.

According to the press statement, multi-giga throughput links often require multiple hardware components, large antennas, and high spectrum resources in congested frequency bands, impacting significantly operators’ overall network total cost of ownership.

Huawei “Super Dual Band” is an innovative solution, which bonds the traditional frequency (6-42GHz) together with E-band (71-86GHz) in a unique manner, offering increased protection via special link aggregation techniques and advanced Quality of Service mechanisms. “Super Dual Band” solution combines long distance benefit of traditional frequencies together with the large capacity advantage of the E-Band, ensuring efficient multi-Giga transmission for links even exceeding 7 Km.

“The growing capacity demands for fixed and mobile backhaul require innovative solutions on wireless backhaul technologies. The combination of E-Band and traditional microwave frequency spectrum could play a significant role on this direction,” said George Tsonis, OTE Group Fixed & Mobile Network Planning & Development Executive Director.

According to Bob Chen, President of Huawei Microwave Product Line, “Huawei has started microwave cooperation with the OTE Group, member of Deutsche Telekom Group, since 2009 and we are very honored to be Deutsche Telekom microwave transmission partner now. Deutsche Telekom and Huawei will jointly focus on potential microwave innovation technology looking forward to LTE-Evo and even 5G,”

In Huawei’s submission, years of intensive Radio Access Network development proved that mobile broadband applications increase the need for backhaul bandwidth in an exponential manner.
