Brazilian news journal Teletime says that domestic mobile operator TIM Brasil is currently working to connect around half of its mobile towers to fibre-optics by 31 December 2012. Quoting the president of TIM Fiber, Rogerio Takayanagi, the online portal says that the operator’s target is to have deployed fibre in 42 municipalities by that date, at which point it will carry around 50% of TIM Brasil’s traffic. The carrier has already connected 70% of its base transceiver stations (BTS) in Rio de Janeiro and Sao Paulo to fibre, and aims to add another ten cities by the end of this year – including Belo Horizonte, Brasilia, Curitiba, Porto Alegre, Recife, Fortaleza and Salvador. Responsibility for the infrastructure investment programme falls to TIM Brasil’s Intelig subsidiary. The carrier has also announced that its CAPEX plans include provisions to in increase the number of transmitters at its towers to 253,000 in 2014, up from 157,000 last year.
