Voice traffic takes up a very small share of the allocated f

Denis Kuskov, CEO of TelecomDaily, expects that the volume of traffic transmitted via VoLTE will continue to grow. "This is a forced, but positive measure. Forced, because there are few frequencies and they are moving to LTE. Positive, because speeds are growing. Considering that there are no base stations, the effect is rather positive," Denis Kuskov said.
requency bands, notes Sergey kazakhstan whatsapp number database Efimov, CEO of the Association of Telephone Operators (AOTS). "Even if we expand the 4G band at the expense of the 3G band, this will force users of cheaper phones to buy more expensive ones. In places where there are problems with the bandwidth, mobile operators use Wi-Fi ranges. The pursuit of increasing the speed of data flow transmission is more of a marketing nature. The government has long called on operators to share both frequencies and base stations, but this contradicts the principles of competition as understood by mobile operators," said Sergey Efimov.
He assumes that the quality of voice communication will not improve, since base stations are gradually failing, and there are no domestic stations yet, as well as imported supplies. "There is no need to rush to abandon 3G yet. Quality can be improved by creating economical versions of sites and portals, especially for mobile networks," believes Sergey Efimov.
Still about half of the traffic goes in CS (Switched Domain). VoLTE is PS (Packet Domain).
It is good to talk about disabling GSM/3G in the Western regions inclusive of the Urals and the Volga region, where the communication channels are relatively good, there is a reserve. The point is that if the channel to IMS or IMS itself drops, VoLTE ends there. Each operator has a switch in each region. So what kind of emergency is there in the region... and so what?
No more than 5% of MTS subscribers in Russia use devices without LTE support.
Plus we add subscribers with phones on which VoLTE did not start for some reason. For example, a phone with firmware for another region of use.
Such subscribers, when making a voice call, drop in CSFB to GSM or 3G. Where can such subscribers be served better, in GSM or 3G?
freeing up frequencies will not only improve the quality of voice services, but also increase the speed of mobile Internet by about 30%
We are talking about frequencies 2100, where each operator has 15 MHz. If you refarm the remaining 5 MHz, the figure is about the same. But the operator also has other frequencies - 2600 (FDD and TDD), 1800, 900 and 800, which are almost never used compared to Megafon and Tele2. As a result, 10 percent!
"A call via LTE is more comfortable, since thanks to modern voice codecs, the voice quality is better there, so with stable LTE it is better than 2G," said Alexey Slukin.
And routing has nothing to do with it? A call in St. Petersburg from a Moscow Beeline SIM card to a St. Petersburg MTS number:

We look at SPD (speech path delay), RTT (round-trip time) - this is similar in the Ping RTT Packet Domain.
Under 3 seconds of two-way delay - this is like in Sputnik. =) If you turn off VoLTE, the delay time is about 600 ms. That is, optimal routing works even at the inter-operator level. In VoLTE, traffic obviously goes to Moscow, and from there back to St. Petersburg.
MOS POLQA SWB is a five-point assessment of the quality of voice call transmission on networks using the most modern Super Wide Band algorithm.
It is clear that the indicator is below the baseboard. Disconnect from VoLTE, and on a short route even on old codecs the quality will be noticeable and the assessment is about 3.5. If you use 3G with the maximum codec AMR-WB 23.85, the assessment will grow to 4.
