Huawei Technologies claims to have successfully completed trials for HSPA+ Dual Carrier network tests for Portugal-based Sonaecom’s Optimus achieving download speeds of 41.4 Mbps with average download limit of 39.7 Mbps.

On the tests, Mr Pinto Correia, Optimus Board Member, stated, “The success of the HSPA+ Dual Carrier technology tests reinforces the high quality of our network and represents the confirmation of Optimus as the best integrated telecommunications operator in Portugal. Optimus was one of the first European operators to develop a technological partnership with Huawei, and that has allowed us to introduce several innovations in the Portuguese market, which represent truly benefits to all our customers”.

Dual Carrier technology is based on the principle of using two carrier waves, both on the transmitter and the receiver, which allows the increase of the transmission rate to double the current maximum value (21 Mb/s).

Mr. Xie Xinping, Managing Director of Huawei Portugal, said, “We are working closely with leading operators, such as Optimus since the introduction of 3G technology. Implemented with dual carrier capabilities, Huawei's HSPA+ solution will enhance spectral efficiency and provide capacity gains for operators. With the widespread adoption of mobile broadband, Huawei is well positioned to provide its customers with a faster and better mobile broadband experience.”

Huawei claims to have already established 36 HSPA+ networks with global operators, among which 20 HSPA+ commercial networks and 16 HSPA+ network in deployment or in trial.
