São Paulo, November 1 - Claro, a pioneer in 4.5G tests in Brazil, announces along with Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated, and Ericsson the completion of network tests aggregating 2600 MHz and 1800 MHz frequencies. The pilot project, which took place in Araras, São Paulo, reached speeds up to 682 Mbps and used a Qualcomm® Snapdragon™ X16 LTE modem test device. The tests showed the possibility of obtaining improved network performance on the road to 5G.

In the tests performed at Rio Verde, Brazil, in December 2015, Claro aggregated frequencies at 2600 MHz, 1800 MHz, and 700 MHz, acquired from a previous auction. At that time, each spectrum had only one band released. For the Araras tests, the 2600MHz spectrum already operates with two released bands, increasing the capacity of utilized frequency.

"This is an important step for the evolution of the mobile networks in Brazil, and one more action from Claro to offer a better experience to our customers. This work started months ago, with the tests at Rio Verde, where we reached speeds of 300 Mbps in our network. Now, we are doubling this result, even without the spectrum 700 MHz spectrum that is still on going. We are pleased be a part of this action along with two leaders of this mobile industry, Ericsson and Qualcomm Technologies," says André Sarcinelli, Director of Engineering, Claro Brazil.

To reach this speed, in addition to the aggregated frequencies, optimizations of the LTE network software, available today, were performed. The combined features include the use of 4X4 MIMO technologies, which doubles the data transfer capacity to the user's smartphone, allowing better data transfer capacity; and 256 QAM, which increases modulations in the available spectrum and improves the efficiency of the network, multiplying the transfer rate to 1.33 to the mobile stations.

"The LTE–Advanced and Gigabit LTE patterns will allow operators to offer a speed increase to their customers, as we pave the way toward 5G. Ericsson has a commitment to the evolution of mobile networks and the Brazilian market, bringing the most recent and innovative technologies available internationally," says Eduardo Ricotta, Vice President of Ericsson Latin America & Caribbean.

"Qualcomm's Snapdragon X16 LTE modem is one of our most recent technology modem innovations, in addition to being an important step toward 5G. We're very confident to work with Claro and Ericsson to bring these innovations to Brazilian users," says Rafael Steinhauser, Senior Vice President and President, Qualcomm Latin America.

This type of architecture and transmission capacity in the access radio require further optical capillarity to the backhaul, fortress that the group has, both on-site access to the Net's network and the long distance with Embratel.

It is with the synergy of infrastructure of Claro, Embratel and Net that can evolve to deliver the best content and applications, in all locations and devices you require. Be it a person, a residence or a corporate user.

Rio Verde

In December 2015, Claro was the pioneer provider in performing tests on the 700 MHz frequencies in an external environment in Brazil. The 4.5G pilot project aggregated three frequencies: 700, 2600 and 1800 MHz This combination made it possible to reach speeds nearing 300 Mbps.
