Informa Telecoms & Media expects the number of femtocells deployed by the end of 2013 to exceed the 40 million mark, with 22 million net additions in 2013 alone. This installed base could help operators to make significant savings by offloading up to 8 per cent of total mobile traffic to fixed networks via the end-user subscriber line. However, whether these savings materialise depends on such factors as the nature of the operator, the mobile access technology involved, the value proposition to the end-user, the region targeted, and the level of investments the operator has already made in upgrading its mobile network.
