1000 to 3000L upgrade question

Since my reply was marked spam for some reason, ill make a new post

Tommaso,

If you're only deploying 802.11n subscribers then you won't see a benefit with an ePMP3000L AP. The ePMP3000 line employs the 802.11ac wave 2 chipset so compared to its 802.11n predecessors of ePMP1k/2k it's capable of a higher modulation mode (256QAM), larger channel size (80MHz) and the ePMP3000 is capable of 4x4 MU-MIMO while ePMP3000L is a 2x2 SU-MIMO device. Since the 802.11n radios cannot modulate up to 256QAM or operate in an 80MHz channel size they won't be able to take advantage of the new features of the ePMP3000L.

On a related note, if you were to deploy an ePMP3000 AP with a 4x4 MU-MIMO antenna it would be able to beamform to the 802.11n SM's and grant a 3dB gain on the UL due to array factor gain. 


In regards to the lack of gain for a 802.11n network

Knowing that current 1000 AP's have a max frame usage which can limit the total possible throughput. Would the 3000L see the same max throughput? Or would it allow a higher total throughput in the exact same setup?. So if i have 20 customers on the panel with all near 14MCS and link tests of something along the 70/10 lines, but realistic we only move a total of 60ish mbps at 100% frame usage. Will the 3000L allow more total? I know the 3000 do not show a frame usage, so i cannot compare to the 3000's we have deployed
