We use all the AF products except the 4x. Here are some observations from the field.
The AF24 is impressive. And consumes 51 watts. If it rains, link will fail.
The AF5 iworks well but it does degrade with any Cambium product nearby. Affects all Cambium products as well.
The AF11FX is better than the Mimosa B11 in terms of latency but not throughput. It is more spectrally efficient. It is not comparable to the 820c or s in any way other than they require an 11Ghz license.
AF2, 3, and 5x radios are comical. ePMP stomps on the AF2x and AF5x in moderate to high interferance environments. Where the 2x and 5x are barely operational (<10Mbps), ePMP will come through with MCS14 and MCS15. Non-GPS model as well but you are constrained by the FE interfaces. Seal the Cat5 caps on the AFx with something or rain will blow up into the radio and it will fail. They are cheesy. NxN? Good luck with that.
AF3x offers a 40Mhx channel width in NA. So it is usefull to near 200Mbps FD currently if everything is perfect.
Other considerations are PPS limits and how PPS affects latency. This is where Mimosa falls apart. AF11FX too. 500Mbps indicated capacity = 400Mbps throughput at 40k PPS. Pathetic. 820s sub ms RTT ramps to 8ms on B11.
Lack of SFP cage is going to be an issue for Ubiquiti BH with fs.com selling BiDi lasers for $9.
Were MikroTik to pick up the code from Bitlomat (Fluidmesh with Nokia engineers), they'd walk on water. No halfduplex radio beat Bitlomat in terms of throughput, multipath or interference robustness.
Conclusion -
For economical PtMP, ePMP is the only choice. For many reasons.
