The UBIQUITI NanoStation NANOSTATION-M2 is a device working in 2x2 MIMO (Multiple Input Multiple Output) standard.
Using bi-polarization antenna with 11dBi gain and MIMO standard operation allow to establish more efficient links.
The NANOSTATION-M2 is additionally equipped with 2 LAN ports, which one provides PoE supply function (PoE Output), and the other allows to access the next device to the network without the use of additional switches.
