1- Dual band is a must these days.But i have a feeling that outdoor 256qam with 160mhz channels won't work very well...
For most outdoor deployments, the correct antenna choice and placement is so much more important than the technology of the radios, that, future-proofing aside, i see no compelling reason to try out AC
(keeping in mind that, as most consumer equipment only really works well in G/N mode, and 20mhz fixed channels, we plan our public-outdoor networks based on those constraints)
I would buy a better antenna with a standard technology radio attached/in it any day of the week.
2- Consumers/Event guests don't tend to keep their devices's antennas oriented in H/V, it is a very chaotic scenario in that sense.
You guys think that MiMo 3x3 would be able to work better with standard 2 antenna equipment? if that's the case, then yes, we would pay more for it.
If 3x3 would only affect "3x3 ready" consumer equipment, then we have the same problem we have with AC tech: Our connecting device demographics wouldn't benefit from the feature.
3- What difference does it make? the majority of consumer equipment will take at least 3 years to start to really benefit from AC-1, let alone AC-2.
4- Make the transmitters clean, if possible with better "knee" / edge-roll-off characteristics so we can put more channels closer together.
26dbm is waaay past overkill. I've never seen a cell-phone putting out more than 14dbm conducted power, and laptops are usually in the 18dbm region.
Keeping in mind the bi-directional nature of wi-fi comms, there is little point having an AP that can talk way much louder than the devices connected to it.
An AP with 30dbm output power would only confuse the device's roaming algorithms, and the guy with the 14db tx-power cell-phone would be shouting profanities about the full-bars wi-fi network that won't connect.
it is a very misleading capability, that perpetuates the myth that "more power is better".
5- really depends on what part of the world you're in?
6- USB port, so we can plug in an NFC terminal, Mr.user touches his iphone and pays for 30mins connection with Apple-pay?
7- Standard. so it will be compatible with all POE switches out there.
If there would be a secondary-aux port, standard is good too, as the new epmp gear supports it.
8- 512 user density with csma protocol? I think radio-side roaming and "user number ballancing" would give better results.
But i don't have any issues with the AP's being able to handle an arbitrary number of users.. :)
9- USB port is a very cheap and almost guaranteed way to make future expansions..
