Super efficient implementation amazingly simple.

I plug in a RJ45 cable coming out of the BOX free - revolution on the Airport terminal.
I plug the Airport terminal to the sector.
I parameter with I phone that recognizes the terminal (Very, very, very simple) almost Plug and Play.
I connect to the wifi network created, or it can extend an existing network.
I have deported a RJ45 cable 1 or I have my box, I like the DRC or to surf with my IPAD, I have my airport that difuse the stable and fast wifi.
Whereas before I hardly could use signal too weak, now it is a treat.
Beware the power and range may vary depending on the distance and walls, my box diffuses the wifi on the 1st floor, my Airport diffuse the wifi on the ground floor. You can verify network performance with apps Nperf.
I had tried a repeater wifi, 1d after inefficiently setting nightmare, return to sender repeater and purchase of this Airport Terminal. Apple Congratulations you're the strongest.
