Ericsson announced that Angolan operator Unitel has successfully demonstrated LTE-A Carrier Aggregation technology on its network, based on equipment supplied by Ericsson. The demonstration was made on both 1800MHz and 900MHz spectrum bands on a commercial network, using a commercial terminal, and took place on 18 December, when Unitel transferred data across its live network in Luanda, Angola, carrying commercial traffic.

LTE Carrier Aggregation is the next step in the evolution of high-speed mobile broadband services, enabling operators to make the most of their existing spectrum assets by combining multiple spectrum bands to enable higher mobile broadband download speeds. Unitel did not indicate when it will deploy the service commercially.
