.a has only 54Mbit/s Phy rate. RB800 is quite powerful. With N/AC you see a lot more cpu work.
With TDMA protocol the cpu has to work in fixed cycles with low latency. So if it is busy while it has to send the next map for the cpes at an exact timing the whole sector suffers. So the cpu should stay at a low level to keep the protocol running. Von: Af [mailto:[email protected]] Im Auftrag von Mike Hammett via Af Gesendet: Donnerstag, 30.

If you're running NV2 on an A card in an RB800, your CPU is going to be low, but your radio is going to be very busy and yet not including that information. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com <https://www.facebook.com/ICSIL> <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> <https://www.linkedin.com/company/intelligent-computing-solutions> <https://twitter.com/ICSIL> _____ From: "Stefan Englhardt via Af" <[email protected] <mailto:[email protected]> > To: [email protected] <mailto:[email protected]> Sent: Thursday, October 30, 2014 2:19:30 PM Subject: Re: [AFMUG] Feature Request of all radio manufacturers: Radio utilization or duty cycle meters This is not quite right.

Tell me how busy the AP is so I know how much more can fit... and break down into different categories why it's busy. TX, Rx, retransmit, overhead, MCS 15, MCS 0, which stations are using what percent, etc. I'd say that knowing how busy the radio is is more important than knowing how many bits are flowing through it. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com <https://www.facebook.com/ICSIL> <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> <https://www.linkedin.com/company/intelligent-computing-solutions> <https://twitter.com/ICSIL>
