Huawei, Optimus conclude dual carrier tests

The HSPA+ Dual Carrier technology, which, together with the HSPA+ technology which has already been implemented in Optimus' network, allows maximum download speeds of up to 42 Mb/s on wireless Internet access.

The tests, performed 100pc on the Optimus network, reached maximum download speeds of 41.4 Mb/s, very close to the theoretical limit of this technology, and the average download speed reached 39.7 Mb/s.

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).

Pinto Correia, Optimus Board Member, said: "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".

This capacity has been placed at the service of its customers through the continuous evolution of the Optimus Kanguru service, a pioneer in wireless Internet access in Portugal.

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."

As of January 2010, Huawei has established 36 HSPA+ networks with global operators, among which 20 HSPA+ commercial networks and 16 HSPA+ network in deployment or in trial.
