IgniteNet has done a good job at getting them to work at more than a mile with no problems by using the edge of the 60GHz band. Now, does that mean it’s going to work near the ocean, the Midwest near the lakes, etc…. at those distances? Of course not. But it will work for ½ mile at least in most cases and drop to 5GHz when it can’t. Considering the distance you will use it at, 5GHz at PTP for ½ mile is still going to pull 200Mbps or more.

I'm definitely able to be wrong, and I don't need to smoke anything to be wrong. I've done 60ghz exactly zero times. I've smoked things I probably shouldn't more than zero times, but zero times in the past 15 years. I'm just taking free space loss and adding tx power and antenna gain from the spec sheets, then comparing to RSSI required for a given MCS. Seems like 1/2 mile for top performance and maybe you get MCS 1 at 5 miles.

I want some of whatever you're smoking because it must be some primo stuff. If you put up a few 500 to 800 meter distance 60 GHz PTP links and monitor them over a multi month period, you'll see that you really don't want to go much longer than that. I can't imagine that the gain of the Ignitenet 60 GHz sector antenna is much better than a typical 25, 30 or 60cm parabolic antenna used for 60 GHz PTP stuff. If I had to guess the 60 GHz PtMP will be reliable at distance of more like 400-500 meters, tops, with properly aimed CPEs.

It's understood that the 60ghz connection will go down due to rain fade, but the built-in 5ghz backup should keep the customer trucking (with reduced capacity). I think you'd be installing at ranges of 1-3 miles for the 60ghz to run at decent MCS, and at that range I think you'll still get decent capacity out of the 5ghz. You'll get a lower speed test, but I'd bet it's possible to design so that Netflix keeps running. ------ Original Message ------ From: "Chuck McCown" <[email protected]<mailto:[email protected]>> To: [email protected]<mailto:[email protected]> Sent: 6/27/2017 11:38:32 AM Subject: Re: [AFMUG] So Silicon Valley WISP startup gets $7M investment? 1. What is acceptable downtime on pure 60GHz. It is possible to engineering it to practically no downtime although less economical. Zero. If it goes down the phone will ring. With a well designed and installed Canopy system there was no downtime. 2. What is the acceptable backup bandwidth? If there is at least SOME internet available during 4-5" rains, is that acceptable? If you are talking about something built in, then the acceptable backup is whatever fools the customer into thinking that Netflix is not impacted.
