If you have a 40Mhz channel, the B11’s can pull 480Mbps+ depending on modulation rates. If you have 80MHz channels, they can pull 1Gbps. Seriously, if he has them in stock, why go buy more radios? I’m not saying there aren’t different radios out there but I’ve made more money off of one link of B11’s in one year than the net worth of many of the smaller WISPS out there. That being said, we finally hit their bandwidth limit on one link and we are upgrading to PTP820’s in 2 bands for redundancy and capacity. But I wouldn’t have been able to afford the original installation of PTP820’s when we started this project. I still have several links up and haven’t had a single failure. How is that a bad thing?

I think you'd have to go to the Integra to get the full 80mhz with SAF. There are some pretty cheap radios out there now though that can use a full 80mhz. If I remember right, Alcoma and Cablefree both will sell links for somewhere around $4k that will do about 650Mbps on an 80mhz channel... but I have no experience with either one, other than that I got pricing from them both at one point. I think there are some others out there for similar prices as well.

I thought the Luminas (at least the ones I have) can only do 56Mhz or something, as opposed to the new ones that can do the full 80 mhz? If I had a Lumina where I can jump up the channel size, that would be ideal, another 30% throughput. Couple that with another link on the same antenna would be hippie skippy 😊 From: Af [mailto:[email protected]<mailto:[email protected]>] On Behalf Of George Skorup Sent: Friday, October 27, 2017 11:51 AM To: [email protected]<mailto:[email protected]> Subject: Re: [AFMUG] Considerations for upgrading passed SAF Lumina link I have exactly 1 SAF Lumina link, 6GHz at 30 miles, that does ~360Mbps (56MHz/256QAM weak-FEC ACM). I have fiber on both sides of this link, so the full-duplex is needed. And even if it wasn't, I'd still want it for the sub-millisecond latency, and rain fades on other paths causing traffic reversal. We'll probably end up upgrading that to an IP20/PTP820 within the next year or so. So when you say 270Mbps... is that a 40 or 80MHz (56 usable) channel? But I thought 40MHz would yield ~250Mbps on a Lumina? Anyway... if it's 40, can you re-coordinate for 80? I'd also agree with what others have said, get another set and do 2+0 since you want to keep the same antennas. I'm sure you can still find an OMC or whatever SAF calls it.
