Huawei has showcased 4-Carrier Aggregation (CA) solution for LTE TDD at the 2013 Mobile World Congress. According to company, solution utilizes 4×4 MIMO (Multiple Input Multiple Output) technologies to provide 1 Gb/s data speeds with a single RRU. 

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 80 MHz 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. 

Company 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.
