Telefonica Deutschland has announced that it will shortly activate Voice-over-LTE (VoLTE) technology within the O2 network for smartphone devices, as soon as manufacturers provide the compatible firmware. The first to be activated for VoLTE from this month onwards will be the Samsung Galaxy S5, to be followed shortly by the Nokia Lumia 830 and 640 handsets, as well as the Sony Xperia Z3 and other models. ‘For us as a leading digital telecommunication provider, the implementation of VoLTE establishes the next important step towards providing the best network experience for our customers,’ noted the firm’s COO Markus Haas, adding: ‘Making calls directly via the latest mobile communication standard completes customers’ LTE experience of the O2 network.’ Telefonica says that the new technology will provide higher speech quality and shorter call setup times across the O2 network. Circuit-Switched Fallback, which automatically switches calls from the LTE network to GSM or UMTS networks, will continue to be available for all customers whose smartphones are not VoLTE-enabled or nor yet activated. Telefonica is planning to increase coverage of its LTE network from 62% of the population to up to 90%.
