PT has partnered with Huawei to conduct the first 4.5G mobile network demonstration in Portugal, reaching speeds of 1.7 Gbps.
The demonstration also pioneered NGPON2 technology developed in its entirety by Altice Labs in Aveiro to support the connectivity between the mobile stations and the network core.
PT said the need for constant connectivity, anytime, anywhere, has created a real "data tsunami" with the proliferation of video content, Internet-of-Things (IoT) or Machine-2-Machine solutions ( M2M). Thus, the High-speed data transfer needs in mobile networks are increasingly high and are responsible for the evolution of the current LTE (4G and 4.5G) networks to 5G.
In the demonstration held at the Web Summit, the largest technology event in the world, a multiband spectrum was implemented, currently used by commercial 2G/3G/4G networks, complemented by the aggregation of up to 5 carrier frequencies in FDD + TDD and using MIMO technology (4X4 MIMO) and conjugating 256QAM modulation.
During the demonstration, PT and Huawei showcased the latest 4.5G technology solutions using commercial HW and SW platforms, Huawei Lampsite FDD and Macro TDD in conjunction with two prototype devices with the ability to transmit data traffic through five carrier frequencies using MIMO 4x4.
Alexandre Fonseca, CTO of PT
It is a further commitment to the country and our clients, in a commitment to invest in technology and high-speed networks, which will enable the development of increasingly innovative services aimed at improving people's daily lives, such as mobile content, the "Internet of Things" and "Industry 4.0."
Paulo Gomes Pereira, Key Account Director of Huawei Portugal
It is with great satisfaction that we are here today to carry out this demonstration with PT, putting into action the MoU signed a month ago in Beijing and which reflects the long-standing partnership as well as the innovative and entrepreneurial DNA of both companies which is in line with the spirit of the Web Summit.
