That is for certain, gotta use exotic substrates. Not sure even teflon is good at that freq.

I have read that building a 60ghz antenna is a whole new ball game of complicated compared to other bands. Until recently 60ghz antennas where built SOC style, directly on the PCB of the board next to or on the radio itself. I believe this may actually still be the case. Ignitenet's design is based on this smartly utilizing some tricks in the 'feed horn' of the radio from what I recall. I can't find the articles I was reading of course, but it came up when people had taken apart the Ignitenet radio and saw the usb dongle that was used, however, for cost effective 60ghz I'm not sure what else exists for the market.

I tried to get a pair of Metrolinqs to work at just under a mile (which should theoretically work), but I never could get them to link. I tested at about half that distance and it worked fine... I don't remember what the signal was, but I thought at the time that it would probably link with 17dbi less antenna. Even so, 1000' should be workable, which still has a lot of potential. I've been toying with the idea of putting them on street lights - I'm thinking you could do something like one 30 degree sector at the end of each street and cover a block or two. Heck, even if you only figured 500'-1000', you could build a network pretty cheaply using street lights. Of course it is only going to be useful in pretty specific areas... at the majority of our towers 60ghz is going to be completely worthless, but I can certainly find places where it would work.

Would not be the case with any sort of 60 GHz sector antenna, you'd be looking at much less gain. On Mon, May 8, 2017 at 2:39 PM, Bill Prince <[email protected]> wrote: Very location specific.

Lots. Lots of places. I’ve got, and can get fiber up main roads in neighborhoods very easily. What costs me is the last mile backbone that winds across streets and through ROW in front of houses etc. That is the majority of my costs right there. If I can get in with ‘normal’ wireless pricing per AP/CPE but at 1000Mbps I can do the hybrid model easily at much less costs. It will be amazing for potential customers at the moment. Might not hold up over time as bandwidth needs increase, but provides an immediate solution at a fraction of the cost of fiber, with the ‘feel’ of fiber.
