Unitel and Ericsson demonstrate LTE-A CA in Angola

13 February 2015 |


Angolan operator Unitel and Swedish vendor Ericsson have completed the successful demonstration of an LTE-Advanced carrier aggregation (LTE-A CA) solution, capable of supporting data speeds of up to 450Mbps.

The trial utilised 60MHz of spectrum, with three 20MHz LTE carriers split between the 1800MHz, 2600MHz and 2100MHz bands.

“The 450Mbps demo in Unitel’s LTE commercial network ascertains our leading position in technological innovation not only in Angola, but globally,” said Amilcar Safeca, board member and deputy CEO.

“At the same time, it aims at ensuring that our network has the capabilities to be among the most advanced mobile networks in Africa and in the world.”

The trial was carried out on December 5, 2014, and marks the first time a speed of 450Mbps has been achieved on a commercial LTE network in Africa.

LTE-A CA allows operators to use spectrum more efficiently and provide a higher quality service to end-users.

“Mobile broadband is opening up a world of opportunities by facilitating industry transformation and bringing inclusion and empowerment to communities,” said Fredrik Jejdling, head of Ericsson sub-Saharan Africa.

“This is especially true in countries across Africa, where the technology enables access to tools, services, expertise, entertainment and information that was previously out of reach to the majority.”

Operators and vendors worldwide have been experimenting with LTE-A CA, including Nokia Networks, Ooredoo Qatar and Telekom Austria
