Question: what is the difference with the M5?
Document: Works good for narrower radius than regular M2. For point to point you would be better with 5ghz M5 model, if you want fastest speeds, broader bandwidth, and less signal congestion problems. But then, if you use the M5s, you would still would still need another 2.4ghz access point, as most consumer devices do not support the 5ghz band.
I purchased the M2 after playing around and using the M5 as a bridging pair to shoot wifi 1km. the M2 is on the 2.4ghz range and has a built in spectrum analizer, perfect for troubleshooting SNR related issues..something that std ap's don't do.Ubiquiti products are amazing..easy to use..easy to setup and able to run....I am moving my home off of 3 wifi ap's (linksys running DDWRT), and moving over to the UNifi product from Ubiquity.
nanostation wifi antenna. still working with it ,it is above an amatures knoledge to set it up ,have a geek friend working with me to get it going
nanostation loco m2 was just what I needed, setup went well with the help from Ubiquiti and youtube vids. Got almost 100 mbs speeds between buildings.
i use this as client antenna about a mile and half and no complain since i bought it.its not in a good position and still works great.
have two of these about a half mile from each other. I share my internet connection with my shop. Have as good of a signal as I do from my wireless router in my house.
great adapter, I use this nanostation m2 and have long range, I connect a wifi station and is far away from my home and have great performance
compre 4 equipos de estos, los verifique cada uno, y todos funcionaron perfectamente, con ellos he logrado enlaces wifi de mas de 3 km, lo maximo ha sido 5km con linea de vista.
attention 5ghz n est pas standard dans les terrains de camping il faut choisir 2,4 ghz qui est plus universel
artifacts that don't exist in real life. It also runs way too slowly on this particular product. Typically, on other UBNT products, Airview will update at 20-30 Frames Per Second. However, on this device, with the latest firmware (AirOS 5.5), the updates only occur at 1-2 FPS.You can verify that the signals are fictional by narrowing the range of frequencies that you can see, i.e.
Answer: The M5 is functionally identical to the M2. The M5 operates in the 5 Ghz frequency range while the M2 is in the 2.4 Ghz range. Benefits of using 5Ghz is usually much less interference from other wifi access point signals. However the 5Ghz doesn't penetrate walls and trees etc as well as the 2.4 Ghz. That being said as long as you have a clear line of sight it should work fine.  Really depends on what purpose you are using the Nanos.  Antenna gains tend to be somewhat higher for the same physical size at 5 Ghz. I would expect the ranges between two identical M2's or M5's to be similar provided you have a clear line of sight and minimal interference from other radio sources. Of course a M5 can not connect to a 2.4Ghz wifi access point. But many newer routers are "dual band" and have a 5Ghz access point too, if enabled.
