More Efficient Infrastructure and SelectiveSwitch-Off
Old generations of Rectifiers can be renovated using the power savings to pay the bill. Four years payback periods are not difficult to find.

Telefonica has already 225 renewable base stations, as well as many renewable fixed sites.We are currently performing an assessment, supported by GSMA, to implement
another 100 sites in Latam in 2011, aiming at 3 years payback periods.
