In the latest series of fixed and mobile broadband quality measurements, Oi was once again the worst-performing operator, having not met the minimum targets in several Brazilian states and even worsening its performance compared to previous assessments.
"On the results of broadband quality measurements by Anatel, Oi stresses that the cases in which the stated goals were not met have been mapped and are being carefully analyzed and addressed by the company," the operator said in a statement sent to BNamericas after being questioned about its performance in the reports.
The operator also said it invested 6.6bn reais (US$2.8bn) last year, of which 70% was used to improve the quality of its telecoms networks "focusing on the pillars of operations, engineering and IT."
In 2013, investments up to the end of Q3 amounted to 4.7bn reais according to Oi, which were mostly aimed at "the expansion and improvement of 3G and 4G networks and the fixed network for broadband and pay TV services.
In the statement, Oi also cited its Wi-Fi network as being a "complement" to its 2G, 3G and 4G mobile broadband coverage. The company has over 500,000 hotspots deployed nationwide, making it the country's largest Wi-Fi network.
