Do you have that much freq /channel available in 5ghz to Burn ? (or thrash for yourself and everyone else ?)
Can one do it with 5ghz, answer is YES, but will it allow you to sleep well at night day after day for long periods of time... chances are NO.... Whatever you can do with 5ghz, you can do with licensed 6ghz (take this a bit loosely) yes the costs may be a wee bit different. FWIW, talk to the folks who are most likely have done something similar. Cambium Exalt and possibly Radwin. Ceragon (licensed) These folks have deep roots in working with Telco world, and as such most likely have done long links over water. Just my 2 cents worth.
