Which driver supports 2300Mhz-2500Mhz and 4900Mhz-5850Mhz frequencies
what do you mean with which driver? in router os these frequencies are supported. you need an additional license, please write to support@mikrotik.com for more info.
Do any cards support up to 6.100 GHz?
So you are using licensed freqencies up there now 
each country has it’s own allowed range. btw in 2.9 you can simply enter what country you are in - and it will only allow you to use the appropriate frequencies
Yes I know, but in NZ, 6.1Ghz is a licensed frequency..and i was just curios as some of the others he was talking about are too…
Yes, your software supports these frequencies, but does any radio support it? The AR5212 Radio (used together with 5213 MAC in AR5004X package from Atheros) is only tunable from 2.3-2.5 and 4.9-5.85.
All the chipset details can be found under product bulletins here:

Maybe some companies have combined the Atheros MAC with their own radio chip? I don’t know. This is why I am asking, are there any wireless cards on the market that support up to 6.100 GHz? If so, which ones?
NZ license fee for the first year of use of 6GHz on a link is only about 600 USD & subsequent years 180 USD. 4.9 is also licensed here, and we can use Mikrotik, but requirements on the licensing include a 30km minimum path and 3meter parabolic antennas. 6GHz has no such requirements and would be very useful to us.
Up there? Where are you, the South Pole? Not too many people live further south than we do.
Seriously though, our business customers are wary of unlicensed and need more range than 20-60 GHz DMR or laser links can provide. And the weather survivability of 6GHz is better than higher frequency links. If we can start deploying licensed links of 8km with Mikrotik costs and ease of install, we have some interesting times ahead of us.
hi John,
Where are you, the South Pole? Not too many people live further south than we do.
may I know where are you located and what are usual {eventually some minimal} winter temperatures there and how often? What is the weather there - does it snow very often and quite heavy?
There are several interesting issues starting from ca. -40 degrees Celsius. All is related to performance and behaviour of radio cards is such cold conditions - also, I don’t know how WRAPs/Routerboards behave with this conditions. Also, have in mind that Atheros cards are optimised for mid-5GHz range and 4.9GHz or 6.1GHz is going to mean a lot of troubles for them. Try to test signal strength in your living room on 5.1GHz, 5.5GHz, 5.9GHz and 6.1GHz - you will see very huge dropout.
bye, mp3turbo.
-40 in new zealand? 
damn, didn’t notice that New Zealand. He was talking about not many people living more south than he is, so I panicked : OMG, South Pole or something.
once again, sorry. I always wanted to spend Christmas on beach in swimsuit.
Am in Otago

Sounds interesting. Have you tried to see who uses 6g stuff already?
I know some people in Christchurch who would be interested in 6Ghz licenced if it was just a nominal increase in equipment cost.
Send me an email or grab me at NZNOG in Hamilton next month. Prefer before I find my way to the bars. 
why not look into using an up convertor?
