LTE developers did not include voice communication in this standard. Therefore, mobile operators are forced to maintain GSM (2nd generation) or 3G networks to provide subscribers with the ability to make voice calls. In order to be able to make calls over an LTE network, its owner is forced to implement a platform for transmitting multimedia content based on the IP protocol (IP Multimedia Subsystem, IMS), and on top of it - the technology for transmitting voice over the IP network Voice over LTE (VoLTE). The growing volume of voice traffic in LTE networks gives mobile operators hope that sooner or later they kazakhstan whatsapp number database will be able to abandon the GSM and 3G standards, reusing the frequencies used for them for LTE and, in the future, for 5G (such reuse of radio frequencies is called refarming).
region became the leader in voice traffic via VoLTE in the MTS network. There, the share of calls via LTE was 48%, while in 2022 for the same period it was 39%. Following the Moscow region is the Novosibirsk region - there the share was 43%. In the Ivanovo region, St. Petersburg and Leningrad regions, Krasnoyarsk and Perm territories - 40%.

Rostov and Sverdlovsk regions and the Chuvash Republic. There, the ability to call over the LTE network appeared at the end of last year. In the Kaliningrad region, VoLTE traffic increased sixfold, in the Mari El Republic - more than four and a half times, in the Kursk region - four times.

No more than 5% of MTS PJSC subscribers in Russia use devices without LTE support. "This share will decrease in the coming years, which will allow us not only to transfer all voice traffic to LTE, but also to complete refarming - reuse 3G frequencies in 4G networks. And the release of frequencies will make it possible not only to improve the quality of voice services, but also to increase the speed of mobile Internet by about 30%," said Inessa Galaktionova, First Vice President for Telecommunications Business at MTS.

A representative of the press service of PJSC MegaFon told ComNews that the operator is also seeing growth in this area: "For the first nine months of 2023, compared to the same period in 2022, the share of VoLTE traffic in the MegaFon network exceeds 60%, and in Moscow - more than 70%."
