Thanks, that helps a lot.
So version 1 I understand.
Version 2 is working as a receive for the existing Wifi signal. Would this also have to be setup at 20 mHz as in version 3?
Version 3 is working as a transmitter sending the signal.
For Version 1 (2 units), I could use them at the higher 2.4 GHz or 5 GHz depending on the unit? Is there some kind of conversion needed at the receiving end?
Do both ends utilize the POE adapter?
Ver 2 would need to be on the same channel width as the existing wireless router. If its a 2.4ghz only wireless router (not dual band- both 2.4 and 5) then yes it needs to be on 20Mhz channels.
Keep in mind that Ubiquiti makes a 2.4ghz and 5ghz nano station. They arent interoperable(not dual band) so if u used 2 they both have to be the same model.
Also keep this in mind, 2.4ghz goes farther and penetrates objects better but has less available bandwidth and more interference issues due to there only being 11 channels total and only 3 non overlapping channels. If theres other wireless aps in the area with good signal, u need to make sure to setup all your devices on channels that are different than the other aps. However, because of the limited channel spectrum and only 3 non overlapping channels, this can be difficult. Also, if u have multiple APs, make sure theyre on different channels or are far enough apart on the same channel so that they dont interfere with each other.
5Ghz doesnt have the same issues as 2.4Ghz. It has more channel spectrum available and way more bandwidth however it doesnt go as far and has issues penetrating objects(keep in mind wireless signlas dont bend around corners or objects. They have to go directly through them)
Question 3: Version 1 needs to have the same radios on both ends. 5ghz is actually higher than 2.4ghz as far as which units to use in your situation, it all depends on the environment so i couldnt say sitting here on my phone. U have to do some analyzing to figure that out. And no there isnt a converter needed. The 2 radios talk to each other.
Yes each radio needs a POE(power over ethernet) adapter. But the radios come with them. Keep in mind, if u have a POE switch, u cant use it for mich of Ubiquitis equipment because they use 24v POEs(which isnt a standard POE voltage). If u plug these into a POE switch(48v) u will instantly burn up the radio.
