Hmmmmm..... Yes / No....sort of.... Things get interesting when you realize that 60ghz Band has been extended to include (57ghz to 71ghz) BTW.. the antenna gain (60ghz) is 42dBi on the 60-35 units.
Right now the current chip set supports up to 64.8ghz .. which has a significantly less oxygen fade then 59/60ghz channel... Will we see a PTMP doing 1-3 miles ? not very likely Will we see a PTP doing 1-3miles ? Yes, very likely.... (there are folks who are running/testing 1mile links). Will it have rain fade ? Yes Hope that clarifies !
