Telecom network vendor Huawei has achieved peak download rates of 63Mb/s during the tests of 3-Carrier-High Speed Downlink Packet Access (3C-HSDPA), clocking 50 percent increase in downlink user speeds compared with Dual Carrier-High Speed Downlink Packet Access (DC-HSDPA).
When commercially available in the coming years, the technology could benefit billions of mobile data users on UMTS networks worldwide, said Huawei.
For the 3C-HSDPA test, Huawei utilized the latest version of Huawei’s access network equipment and the Qualcomm Snapdragon 801 processor. In 2013, Huawei and Qualcomm Technologies completed a joint test of DC-HSUPA (Double Carrier High-Speed Uplink Packet Access).
Wang Yixiang, president of UMTS Domain in Huawei, said: “The relevance of higher speed downlink is also of significance for a growing number of multi-carrier networks, especially 3G 900 MHz and 2100 MHz band network deployments where improving download speeds through multi-carrier aggregation technology is critical for maintaining user experience and retention.”
Release10 of 3GPP introduces 3C-HSDPA technology, effectively aggregating three carriers for a single downlink subscriber over one or two mainstream UMTS bands at 850-900MHz and 2100MHz. Bringing superior service experiences for mobile broadband users and significantly boosting multi-carrier aggregation efficiency, this technology also improves the efficiency of wireless spectrum usage.
