At the Mobile World Congress 2013 in Barcelona, ​​Huawei first demonstrated the TD-LTE-based four-carrier aggregation (Carrier AggregaTIon) technology, enabling a single RRU to achieve 1Gb / s in the industry under MIMO 4X4 conditions The highest rate sets the benchmark for the broadband network era, and individual users can enjoy higher TD-LTE download rates in the future.
In recent years, with the evolution of LTE networks, wireless networks are developing in the direction of multi-mode and multi-frequency. At the same time, the widespread use of mobile broadband has made end users' requirements for mobile data service rates increasingly higher. , Deployment and other aspects are increasingly challenged. In the LTE-A era, carrier aggregation has received intense attention from operators around the world. It can double the download rate of single users without affecting network capacity.
The TD-LTE four-carrier aggregation technology demonstrated by Huawei this time is equipped with Huawei's TD-LTE ultra-broadband series RRU, which supports 80MHz large bandwidth. In the future, only software upgrades can expand the network to 4 carriers, achieving a high 1Gb / s Transmission rate. As early as the TDSCDMA era, Huawei helped China Mobile take the lead in launching broadband RRUs and stayed ahead in TDD broadband. At the 2013 Mobile World Congress, Huawei's TD-LTE ultra-wideband RRU combined with 4-carrier aggregation undoubtedly pushed broadband technology to a higher level. Broadband development of wireless-side equipment will help operators' network investment in one step and achieve long-term stable development of the network.
In the first half of 2012, Huawei dynamically demonstrated TD-LTE-based MIMO 4X4 two-carrier aggregation at multiple analysts conferences such as the Global Analyst Conference and the CTIA (Cellular TelecommunicaTIons Industry AssociaTIon) in the United States. In the 2X20MHz networking environment, the single user peak rate Reaching 520Mb / s, Huawei's TD-LTE carrier aggregation will be truly commercial end-to-end in 2013.
Huawei TD-LTE has always been committed to providing the best performance commercial networks, providing the best user experience in network convergence and evolution, providing rich terminals and innovative services, and ensuring the business success of operators end-to-end. Up to now, the TD-LTE network deployment provided by Huawei for the world has covered the core regions of Asia-Pacific, Middle East, Europe, America and Africa.
