55 km wireless link is possible,minimum 10Mbps throughput which device you preferred (mikrotik or eny product)
That is a long long link. I hope you have a tall tower to mount equipment on as line of sight will be hard.
If the link was not so far, I would use Sextant on both ends, but I do not know if that would work for you.
You will need a very directional and high gain antenna to make this work. A directional antenna puts the signal into a very tight beam and does not ‘spread’ the end of the beam so bad.
Don’t use SEXTANT this is to weak for this.
I think Netmetal units with mANT30 antennas.
Remember the laws of your country.Concerns the legal broadcast limit
Thats very funny.
You need 30dbi anntenas (at least) and 2 radios like netmetal or basebox5.
I agree Sextant is not enough.
Good grid antennas would also be good if you don’t need MIMO. If MIMO is needed - dish antennas.
And of course extremely precise alignment.
Most of the regulatory domains make this kind of link impossible.
