Claro Brasil has teamed up with Ericsson and Qualcomm to stage a successful 5G New Radio (NR) data trial at the cellco’s headquarters in Sao Paulo using its existing 4G frequencies. The tests used Ericsson Spectrum Sharing functionality and a 5G smartphone prototype, equipped with the Qualcomm Snapdragon X55 5G modem RF system.
Andre Sarcinelli, engineering director at Claro, commented: ‘The sharing of existing spectrum will allow Claro to implement 5G in an agile and dynamic way as the penetration of 5G smartphones grows. And, at the same time, it will allow the operator to rationalise its investments, optimising its network for coverage and performance in all technologies.’
TeleGeography notes that Claro launched its original LTE network in December 2012, using the 2600MHz band, and went on to upgrade to the LTE-A standard using 700MHz and 1800MHz frequencies.
