Huawei Announces World’s First LTE-A Inter-Band Carrier Aggregation Solution

[Barcelona, Spain February 27, 2012]: Huawei, a leading global information and communications technology (ICT) solutions provider, today announced the launch of world's first LTE-A (LTE-Advanced) inter-band carrier aggregation (CA) solution at the Mobile World Congress 2012 in Barcelona. This solution will significantly improve the utilization of discontinued spectrum resources and increase user peak rate and network throughput.

In an era of mobile broadband (MBB), diversified MBB services and increasing data traffic used by individual subscribers have huge impacts on mobile networks. Scarcity of spectrum resources, however, prevents proportional increases in network capacity. Recent years have seen considerable discussion over how operators can effectively utilize spectrum asset for greater capacity.

At the Mobile World Congress 2012, demonstrations of Huawei's LTE-A inter-band CA solution showed inter-band carrier aggregation at 800MHz and 2.6GHz with peak throughput of over 225Mb/s. The solution is expected to revolutionize user experience by allowing networks to meet bandwidth requirements of data-heavy applications, marking an industry milestone and demonstrating Huawei's leadership in field of LTE-A innovation.

Inter-band CA is the most difficult to realize of the three forms of LTE-A CA (continuous CA within the band, non-continuous CA within the band, and non-continuous CA outside of the band). Given existing spectrum allocation policies, inter-band CA not only dramatically increases spectrum resource utilization, but also helps operators flexibly combine bandwidth and solve spectrum discontinuity to increase user peak rate and experience. With this solution, Operators enjoy greater returns and spectrum assets will appreciate in value.

"Through customer-centric innovation and strong partnerships, we are dedicated to creating maximum value for our customers by providing competitive solutions," said Ying Weimin, President of Huawei GSM&UMTS&LTE Wireless Network Business Unit. "Huawei has been partnering with global leading operators in the fields of LTE/LTE-A. Huawei's leading end-to-end advantages help operators build efficient, sustainable, and profitable mobile broadband networks, as well as bring people a wonderful service experience."

According to recent reports from the 3rd Generation Partnership Project (3GPP), Huawei has contributed more than 260 approved LTE/LTE-A core specifications since 2010, comprising an industry-leading 20% of all approved contributions. Huawei's dedication to sharing its technological innovations continues to play a fundamental role in the development of the global LTE industry.
