Tele2 AB, announced that Tele2 is the first operator in Europe to have tested voice over LTE (VoLTE) in the live Swedish Tele2 LTE network. The tests proved much better voice experience in the IP based LTE network compared to 2G and 3G networks.
The tests have been conducted in a fully end-to-end standards
compliant manner using technology from Mavenir Systems and Nokia Siemens
Networks implemented in the live LTE network in Sweden.
VoLTE technology improves voice quality significantly and enables much faster call setup times.
Joachim Horn, CTIO Tele2 AB, commented: “We have consciously built in
support for VoLTE in the 4G network, covering almost the entire
population of Sweden. The tests we have conducted have shown tremendous
results in a multi-vendor environment. From a technical standpoint we
could be ready to launch commercially within a year.”
VoLTE is the next generation technology for transporting voice
traffic as an IP data stream in LTE. Today the LTE networks are solely
used for data traffic whilst voice traffic is still handled in the 2G
and 3G networks. By moving and converting the voice traffic to LTE data,
the opportunities for a superior and seamless user experience of voice
integrated in new LTE services and applications are increasing.
Joachim Horn continued: “Not only does VoLTE enable superior voice
and data experience simultaneously for our customers, but the technology
is also more cost efficient”.
