MWC 2013: Huawei showcases first 4-carrier aggregation for LTE TDD

Huawei showcased what it claims was the world’s first 4-carrier aggregation (CA) solution for LTE TDD at the 2013 Mobile World Congress. Utilising 4×4 MIMO (Multiple Input Multiple Output) technologies, the solution provides 1Gb/s data speeds for the industry’s best capacity with a single remote radio unit (RRU).

The company said that the solution establishes a wideband network benchmark, allowing a single user to enjoy higher data speeds on an LTE TDD network than previously possible.

Huawei’s 4-CA solution for LTE TDD is a part of the company’s GigaSite solution for meeting growing end users demands for higher data speeds. It employs a series of Ultraband RRUs which support 80MHz and can expand to four carriers with only software upgrades to achieve a 1 Gb/s data speed.

Huawei has also launched a similar series of Wideband RRUs for China Mobile’s TD-SCDMA network. The 4- CA solution highlights the importance of wireless network equipment supporting multiple broadband frequencies in order to build easy-to-deploy networks that are suited for long-term development.

Huawei has previously demonstrated 4×4 MIMO 2-CA for LTE TDD, which allows for peak data rates of a single end user to reach 520 Mb/s. In 2013, the chipset series will launch to support end-to-end LTE TDD CA.
