Dont try to neglect the newer .ac chipsets are better than 11n chipsets. They have faster processing and they achieve higher modulations at short distance. The fact that UBNT AC do not perform well enough now does not mean that the hardware base is worse compared to older HW. I guess if cambium would use this HW base and add GPS it would perform and scale quite well.

ePMP 802.11n chipset is manufactured by Atheros-Qualcomm. In next generation ePMP ( based on 802.11n radio) will be used the same Qualcomm chipset. But new ePMP hardware ( board with CPU, and also radio) will be more powerful and efficient. We believe, that new ePMP platform will have increased pps, higher MAC TDMA and radio performance. And current ePMP now and next generation 802.11n based ePMP are (and will be) more efficient ( more max CPEs per sector, more sector throughput, lower and stable latency and jitter, lower PER. etc. ) then any N and AC chip based systems from other vendors.
Ubnt AC is based on 802.11 AC wave 1 chipset. They say that AC wave 1 chip is not good enough for outdoor BWA product. It seems new ePMP AC will be based on 802.11 AC wave 2 MU-MIMO chipset ( I suppose , it will be also Qualcomm). At the beginning ePMP AC will be Point-To -Point. In regards to AC multipoint, I would say, that AC in multipoint may be efficient do not due to using 256QAM ( it requires high CINR, that it is hard to achieve in real multipoint network), but due to MU-MIMO. It means that users ( CPEs) in multipoint are separated by timing ( TDMA) and also by using different polarizations. It should increase efficiency of multiple access. May be sometime we will see also Cambium ePMP AC with TDMA MU-MIMO multiple access for multipoint networks. And if it happen, it will be completely other product ( not only GPS sync will be advantage) in comparison with UBNT AC.
2 Possibilities:
1. You are a cambium employee and get fired now as you are whistleblowing
2. You have a realy big glass sphere at home
I would like you get fired ;-)
