Three, Ireland’s largest mobile telecommunications provider, has today announced the launch of its next-generation voice services, Voice over LTE and Voice over Wi-Fi. These new services will allow customers to make and receive calls over 4G and also over Wi-Fi. This follows EIR and Vodafone which previously launched these services in Ireland.

Voice over Long-Term Evolution (VoLTE) is an LTE high-speed wireless communication standard for mobile phones and data terminals, including Internet of things (IoT) devices and wearables. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. It uses less bandwidth because VoLTE’s packet headers are smaller than those of unoptimized VoIP/LTE.

The introduction of VoLTE and VoWiFi will mean superior call quality for Three Ireland customers, as well as faster call setup times and seamless coverage when moving between indoor Wi-Fi and outdoor 4G. VoWiFi will also see indoor coverage improved when Wi-Fi is available as well as allowing customers to retain 4G data connectivity while making voice calls outside of the home or office.

David Hennessy, Chief Technology Officer at Three Ireland and Three UK said: “Annually Three Ireland invests over €100 million into its network, and the introduction of next-generation voice services for our customers is a clear demonstration of this investment. While data usage on our network has increased 275% since 2017, we know how important staying connected through voice calling is and the introduction of VoLTE and VoWiFi will deliver a marked difference in call quality for our customers.”
