What Internet data transmission standards from 2G to 4G are used by Russian mobile operators?

Question

network hardware

It's stupid to take 0G and 1G, I don't need them...
→ In general, which of the listed standards work in Russia?!
• 2G:
"CDMA (TIA/EIA/IS-95 and ANSI-J-STD 008)"
• 2.5G and 2.75G:
"GPRS", "EDGE/EGPRS (UWC-136)"
"CDMA2000 1X (TIA/EIA /IS-2000)", "CDMA2000 1X Advanced"
• 3G:
"UMTS (UTRAN)", "WCDMA-FDD", "WCDMA-TDD", "UTRA-TDD"
"CDMA2000 1xEV-DO Release 0 (TIA/IS -856)"
• 3.5G, 3.75G, 3.9G:
"HSPA: (HSDPA, HSUPA)", "HSPA+", "LTE (E-UTRA)",
"CDMA2000 1xEV-DO Revision A (TIA/EIA/IS -856-A)", "EV-DO Revision B (TIA/EIA/IS-856-B)", "EV-DO Revision C",
WiMAX-Advanced (IEEE 802.16m)

Answer 1

These standards are only in 4G - a dozen or two.
Moreover, in different regions and with different operators - different combinations.

Answer 2

Yes, in general, everything works. Different operators and in different regions have a different set of standards, but to one degree or another they all were or are.
The GSM line is more widespread, mainly because it is used by the Big Three operators (although probably already the four).
CDMA line is used more by regional operators. its frequencies are of no interest to the big three and are easier to obtain.
WiMAX used Yota earlier, it seems refused. Now it is more often used by Internet providers to provide Internet where it is not profitable to pull wires.
LTE is again in the priorities of the Big Three.
