Huawei achieved a peak download rate of 63 Mbps in a laboratory test of 3-Carrier-High Speed Downlink Packet Access (3C-HSDPA). The result represents an improvement of 50% increase in downlink user speeds compared with Dual Carrier-High Speed Downlink Packet Access (DC-HSDPA).
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.
Huawei said continuous improvement to HSDPA potentially benefits billions of users currently on UMTS networks worldwide.
"This is a timely and important milestone in a fast expanding world of smart phones, growing mobile video demand and real-time large file download expectations," said Wang Yixiang, President of UMTS Domain in Huawei. "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."
