Re: Only 3 x 60Ghz bands for 60G devices?

So far it all works out fine: One tower: 4 x 60Ghz Metrolinq's backhauls running towards 200 - 400 meter remote towers. They do backhauling and deliver 200-800Mbps one way traffic what is plenty for us... Same tower: 4 x 60Ghz Mikrotik AP's. Each has at least 2 clients connected, one actually has 5 ...
