Swisscom has announced that 94% of the Switzerland's population can use its 4G/LTE network. For 2G or 3G technology, the figure is over 99%. Swisscom is also now seeking to improve the quality of indoor reception. Coverage inside buildings will be improved in the coming weeks as new mobile frequencies are rolled out and LTE is expanded. From the second half of 2015, Swisscom customers will also be able to make calls on their mobile phone via their home WLAN network with WLAN interworking technology.

Over the next few weeks, operator's network will be expanded to include the newly available UMTS and LTE frequencies. In addition, Swisscom is introducing WLAN interworking, with that customers can make/receive call on their normal mobile phone number without a need to open a separate app. The new technology will be expanded by Swisscom over the coming months and is due to go live in the second half of 2015.

With WLAN interworking, calls are not interrupted by the switch between networks. If reception at home on the WLAN is better than on the mobile network, the mobile phone selects WLAN. Swisscom is offering this service in Switzerland at no extra charge. Calls are charged at the same rate as standard calls on the mobile network. The first smartphones supporting the WLAN technology will be launched over the coming months.
