Hi, I'm looking to upgrade some ubiquiti acces points that are only 2.4ghz.

I think I have narrowed my search down to a 3pack of either the X50 or the X50PoE, I have the PoE in place for the current access points so either will work.

I am just trying to work out which is the better unit? 

Ii see something on the X50 about HE160 and 4 streams less lag thats not listed in the specs of the X50PoE but as a bit of a technophobe I dont know what this will mean for me in use.

I will have 2 of the units in the house on in my loft near my switch and router and anothe down stairs, the other will be at the opposite end of my garden in a summer house aprox 30M away, this has a wired connection from the switch in the house and its own switch to power multiple wall outlets.

TIA for any Help Keith.
