Hello just planning a new micro-pop. plain area, with forest all around. the customers are within 250mt radius. I can get there via a 60GHz link with about 1gig capacity. What about an EPMP3000 L + Omni 13dBi ? I have tried it with a 40mhz channel and worked absolutely great. What about 80mhz? D…

Of course dude. I run 8 towers all on 80mhz and can get over 400mbps to many customers. Inuse the 75/25 too. I recommend setting max mcs manually to keep retransmits to 0%. I dont usually use omni’s, but one tower has epmp3000l with 13dbi ubiquiti omni and another tower has epmp3000 with 4x4 omni. B…

Hi do you recommend to set up MCS manually on the CPEs radio but do also leave DLMax rate on the AP at MCS 9 or do you lower on the AP as well?

Always leave AP on highest possible mcs rate and make adjustments on sm only. Use Monitor - Performance to see what rate packets are passing, then drop rates to match. Keep resetting and running speed test and reducing mcs until all packets pass 100% on the set max mcs rate. Do in both directions.

thank you, one question if a CPE performance % is 90% under MCS8 for example, but I know customer plan in MBPS is 30Mbps DL/10Mbps UL is there any problem if I set up manual rate at Mcs5? I know that at mcs5 can easily do the 30/10 plan. I was thinking to standarize all my CPE at Mcs5 as long as t…

The only reason to reduce max mcs is to keep latency as low as possible, by stopping retransmits. Tune each sm separately and I recommend setting it to one step lower than necessary. ie if you can get 99% of packets to pass at mcs7, set it to mcs6. I would not set all max mcs the same (ie mcs5) beca…

got it thank you I will give it a try.

[image] riddle: running speed test and reducing mcs until all packets pass 100% on the set max mcs rate. Do in both directions. Good gracious. If only there was an automatic way of doing this. You know..like a software algorithm?

There is - just let the radio do it itself :grinning_face_with_smiling_eyes:

well, the radio itself is not so extraordinarily good doing that! A nice feature from a competitor is the “DATA RATE ALGORITM”, maybe “default” or “alternative” (aka conservative).

It’s been a long while since I’ve had to mess around with max MCS rates. I’m wondering if Cambium have changed their algorithm in later firmware releases.
