Claro Brazil partners with Huawei to launch 4.5G

Huawei announced that Claro Brazil recently launched what is claimed to be the first commercial 4.5G network in Brazil, incorporating 4 x 4 MIMO, carrier aggregation (CA) and 256QAM technology, in the city of Brasilia.

Claro demonstrated 4.5G data rates averaging 250 Mbit/s on compatible smartphones during the release ceremony in Brasilia, which is claimed to be around ten times the average rate delivered on the existing 4G network. Claro also announced its new tariff policy at the event, which features increased data allowances for existing packages.

Huawei noted that as smartphones featuring support for both 4 x 4 MIMO and 256QAM become available in the market, users will be able to access the enhanced capabilities offered by the 4.5G network. On the network side, Claro is able to provide mobile Internet access with fibre-like speeds to mobile customers with suitable devices.

Huawei noted that 4.5G Evolution helps operators enhance their networks by introducing 5G technologies into existing 4G networks. This can allow operators to trial 5G-like services and develop the business models that 5G will support in the future.

Separately, Huawei announced that working with French operator SFR it had completed the first pre-commercial field verification of 4 x 4 MIMO technology in France, enabling a downlink throughput of 628.3 Mbit/s using a commercially available phone on SFR's 4.5G network.

The tests with SFR involved a commercial phone operating on the live SFR 4.5G network and served to verify that the use of 4 x 4 MIMO, combined with 2 CC carrier aggregation and 256QAM modulation, can enable throughput of up to 628.3 Mbit/s. Huawei noted that SFR is aiming to extend its 4.5G network coverage to 90% of customers in France by the end of the year, and to increase this to 99% during 2018.


Commenting on the network launch, Claro CEO Paulo C├ęsar Teixeira said, "The commercial release of the 4.5G network, with 4 x 4 MIMO, carrier aggregation, 700 MHz spectrum activation and advanced modulation, will help the Brazilian communications industry to play a significant role in the worldwide arena, as the country is a pioneer in this technology… Claro will use the recently acquired 700 MHz frequency band as a part of its ongoing effort to build a quality, next-gen mobile network nationwide".
