Huawei has completed the first HSPA+ call with an uplink speed of up to 10.4 Mbps to the cellular base station.
This HSPA+ call was configured to HSUPA cat 7, a 3GPP Release 7 feature defining a new channel configuration that supports 11 Mbps on the uplink to the basestation. This next step in the evolution of HSPA+ capabilities also benefits operators through increased spectrum efficiency on the uplink. The call combined 16QAM modulation with Huawei's E-DPCCH (Enhanced Dedicated Physical Control Channel) boosting technology and Renesas Mobile's advanced mobile platform. http://www.huawei.com
