That sounds familiar, did someone from Cambium post awhile back that they were already looking at it? Or am I just experiencing déjà vu?

If an SM is performing at a poor MCS, then its throughput suffers because additional time is not allocated. The other SMs get their time allocated time and do not have their time taken away at the expense of a poorly performing SM.

It's possible they reduce the effect by allocating less airtime to the weak CPE. Basically make the slow one slower rather than making everybody slower. *IF* they do, that's not a unique feature to the ePMP. ------ Original Message ------ From: "Kurt Fankhauser" <[email protected] <mailto:[email protected]> > To: [email protected] <mailto:[email protected]> Sent: 11/21/2016 10:33:42 PM Subject: Re: [AFMUG] ePMP 5ghz issues I dont know how they can make that claim when their "flagship" 450 product will suffer from decreased capacity when SM's with weak signals connect to it and pass traffic. Same thing with LTE. Burns up more airtime so why would EPMP be better than all the expensive gear? Doesnt make sense. Sent from my iPhone Kurt Fankhauser Wavelinc Communications P.O.

At first there was an install on a customers private tower to get service. I noticed the MCS downlink and uplink were sitting around MCS 1 with 80% or so of packets. So it affected all other customers on the AP and brought those other customers into 20% MCS 1 levels. Now his SM has been raised and signals are great, -60dBm, SNR of 37dB, MCS 13/15. The SM is also operating at mostly MCS 14-15 with only 1% in MCS 1. I changed the management to be MCS 0 to attempt to help with the minimal connection to MCS 1 so it will be allowed to pass traffic at that rate. However, this customer still has issues where the internet connectivity is random. Sometimes it just completely drops when you put traffic to it, but when it is on, speed tests of 37 Mbps down and 12 upload. All other customers are still on MCS 1 with levels ranging from 7% to 20%. I can assume they are having the same trouble as the customer listed above. All software is 3.1 My question is, what is the issue? This SM shows nothing but good results, yet connectivity is poor at best, and all other customers are still having issues. I even disconnected the SM that caused customers to have problems and they were still modulating at the 7-20% MCS 1 level. Tried changing channels, etc. but still no results. Any help would be appreciated. Josh
