Claro Puerto Rico has announced that it has conducted LTE-Advanced (LTE-A) tests over its commercial mobile network, in association with Ericsson of Sweden. The vendor has deployed a 4×4 MIMO (multiple input, multiple output) platform, which effectively doubles the number of data paths between a cell site and an end user’s phone, allowing download speeds of up to 300Mbps. The trial also includes 256 QAM (quadrature amplitude modulation) and 64 QAM functionality and utilises the Ericsson Lean Carrier platform to ‘clean up’ the signal space, the cellco’s press release notes. The tests, which have taken place in San Juan and Ponce, commenced on 21 October and are due to conclude today (28 October).
As previously reported by TeleGeography’s CommUpdate, earlier this month Claro revealed plans to deploy carrier aggregation (CA) LTE technology across its Puerto Rican wireless networks in 2017, on the back of a USD370 million investment. Claro’s existing 700MHz LTE network will be augmented with CA, as the operator seeks to use the 2100MHz/1700MHz AWS-3 spectrum it acquired at auction in early-2015.
