Huawei says that it has successfully completed
tests of 3 Carrier High Speed Downlink Packet Access (3C HSDPA). The
trial achieved peak download rates of 63Mb s, a 50% increase in downlink
user speeds compared with Dual Carrier High Speed Downlink Packet
Access (DC HSDPA).
"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."
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.
