You have to have a perfect optical line of sight for mm wave. You cannot have much precipitation. Oxygen absorption hits a max at 60 GHz. Half mile ranges or less in real deployments if you want even 99.99 available. And you want to do point to multip-point. So you lose probably 30 dB right off the starting line due to the difference in the AP antenna and an PTP antenna.
Doug Clark was all over some 24 GHz PTMP product several years ago. I guess it never worked out.

For example, 60GHz and 240GHz. Yes they cannot go very far, but it seems none of the other high frequency stuff can either. And these are very high capacity.

I'm trying to think outside of the box, but every time I do I get back to the same place. Nothing I can do this with is on the market yet or never will be. I'm getting more and more tempted every day to start manufacturing my own stuff. I've already started looking into that. Anything you guys would like to see come to market? If I go into manufacturing I'm going to be all in. Thank you, Brett A Mansfield On May 29, 2015, at 4:19 PM, Rory Conaway <[email protected]> wrote: You need a different strategy.

I know several companies are working on something in 60GHz which would be ideal because it's not a very large area and can be daisy chained into a ring. 80GHz would be fine, but like you said nothing seems to exist. These CCS devices look great and might be exactly what I'm looking for. I just hope the price is right. They are 26 and 28GHz. But I think Vivint has a bit of a monopoly in my area with all of their 28GHz radios all over the place. I'm afraid the noise would be too much, even with the narrow beams.

I don't know if anything exists for PtMP in 80ghz... or maybe 60ghz? It seems like the only real option here is 28ghz.

You can have a whole lot of sync'ed APs/masters at the one site and as long as they're transmitting at the same time and the client/slave sites aren't nearing the different master's you'll be fine.

I need something inexpensive comparatively and it needs to be PtMP. I could use airfibers if I could do PTP, but that would be FAR too many radios in one location competing for airtime. Josh, I currently use 3.65, but I need high capacity. 80Mb at best is not near enough.

If that is the case, then CCS has a 28GHz offering with StraightPath. But not sure what you’re looking at price wise. You may just investigate multiple 23GHz shots or something similar depending on distance. Just want to make sure the request is clear. *************************************************************************** Daniel White - Managing Director SAF North America LLC Cell: +1 (303) 746-3590 [email protected] Skype: danieldwhite Social: LinkedIn *************************************************************************** From: Af [mailto:[email protected]] On Behalf Of Brett A Mansfield Sent: Friday, May 29, 2015 3:42 PM To: [email protected] Subject: Re: [AFMUG] PTMP backhaul solution I'm looking for backhaul.
