Re: Ubiquiti Nano
said by 76580315  :13dB is the absolute lowest we would go on a CPE regardless of power levels. That's twice the gain of a 10dB. 10dB at a 60 degree beamwidth with 400mW has no place in our outdoor deployments. It would spread RF absolutely everywhere we don't want it. Can anyone else here see why you would want a 60 degree beamwidth for a client CPE? especially at 400mW. How much harder would it have been to use a 13dB? Sure, you wouldn't be able to use the Canopy look alike housing with a 13dB antenna. Paul I am going to agree with this. While I somehow think this unit was designed for more indoor installs than outdoor, this is way to much power in such a wide antenna. At 400mw, this unit is going to see EVERYTHING around it for quite a distance. In some of the places I am deploying CPE's, it would probably see at LEAST 30 AP's on a site survey because of the wide beam.
When deploying in areas like the one I just mentioned, it seems the only way to roll is with a very high gain antenna unit with very low power.

| This may explain the small antenna. Europe has much lower EIRP limits. Also noticed there is no way to tilt without purchasing an additional tilt style pole mount.  |

Alvin, TX | Just because it runs 400 mph don't mean it has to run 400 mph. The nice part is you can add your on antenna. You can't buy any outdoor cpe for 79 bucks. |

I have a few of the NS5 and NS2 an the way to test out, I'll post my results after I get them deployed.

The transmit power on the unit doesn't have anything at all to do with its receive sensitivity. Conversely, the wide beamwidth can greatly contribute to picking up extra noise. |

Here again, the higher the power of the radio, the further the signal will travel, irregardless of its receive sensitivity. the more the signal travels, the more noise and other radios it will see.
