Huawei announced it has achieved peak speeds of 63Mbps during tests of the in-development three-carrier HSDPA (3C-HSDPA) technology.

The 3C-HSDPA technology is part of 3GPP Release10. It involves aggregating three carriers over the mainstream 850-MHz and 2100MHz UMTS bands.

The tests used Huawei network equipment and a Qualcomm Snapdragon chipset, building on the collaboration between the two vendors for testing dual-carrier uplink transmission technology DC-HSUPA last year.

In a statement  announcing the trial Huawei said it expects such advances in carrier aggregation technology to “ensure [that] 3G will remain a viable alternative to 4G networks as they get rolled out progressively over time.”

The company added that improving download speeds through multi-carrier aggregation technology is critical for maintaining user experience and retention on UMTS 3G networks.

Over the past few days, Huawei has also announced two networking R&D partnerships with APAC operators. The vendor has agreed to set up a 5G and LTE-Advanced research lab in Seoul with LG U+ and enter a networking R&D collaboration with Telekom Malaysia.
