When I say 270Mb, it means the modulation is on the edge with 3ft dishes which was a conscious design suggestion / decision 4 years ago because of the extra tower cost and wind load.
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]] On Behalf Of George Skorup Sent: Friday, October 27, 2017 11:51 AM To: [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.
