DNA is the first operator in Finland to introduce Voice-over-LTE (VoLTE) technology, i.e. 4G calls, across its nationwide mobile network. DNA’s mobile network has also been upgraded to support Voice-over-WiFi (VoWiFi) technology. The new technologies will enable higher-quality phone calls, better reception indoors, and more affordable roaming calls. The new technologies will be available for pilot customers already during the spring.
Finnish operators’ 4G networks currently only carry data, and all calls are transmitted across 2G and 3G networks. VoLTE enables phone calls across 4G networks, which improves voice quality and shortens the connection time of calls to a fraction of what it is now.
WiFi technology on mobile networks to challenge traditional roaming calls in the future
Voice-over-WiFI (VoWiFi) technology allows users to make phone calls from their home, office, or public places such as airports using WiFi. This improves voice quality and indoor reception, if, for example, the user lives far away from the nearest base station. WiFi calls made abroad will also typically be cheaper than normal roaming calls.
“We want to continuously bring our customers new technologies that improve their experience. We will be testing these new technologies with our customers during the spring, and will then gradually make the technologies available to all our 4G mobile communication subscribers”, explains DNA’s Business Manager for Mobile Communication Subscriptions Mika Husso.
Both technologies are dependent on the handset. Mobile phone manufacturers’ most advanced models, such as Samsung Galaxy S7, Apple iPhone 6S and Microsoft Lumia 950, typically support both technologies. Manufacturers are also expected to make their more affordable models compatible with these technologies in the future.
VoLTE and VoWiFi technologies have already been adopted in other countries around the world, such as in the United States, Switzerland, and the Netherlands. Finnish operators have not made commercial use of the technologies previously.
