Huawei, a leading global information and communications technology (ICT) solutions provider, on Monday launched 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.

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 rates and experience. With this solution, operators enjoy greater returns and spectrum assets will appreciate in value.
