Re: LHG 60G experience

what do you expect more if you bond 5ghz+60ghz? anyway there is 1gbps ethernet port, i dont get your idea (:
my point, just to get ANY connection during bad weather, okay let it be at least 100mbps for snow fall or heavy rain, so the customers would not fuck up to red our phones :)

still under big question, will they beat 2.7-3km range or not, so far as I calculated should be on the limits, with fail-over to existing 5ghz could be a good improvement.
