Ubiquiti LiteAP Sector

The confusingly named LiteAP (LAP-120) is a very good, cheap 120' sector antenna. 120' means you need three to get a full 360'. It used to be called a LiteBeam 5AC AP LBE-5AC-16-120, and is still named that on parts of their website.

We use it as a sector antenna for most hub and supernode installs. As with all Ubiquiti gear you need to flash it with the latest firmware first.

The AC in the name is not 802.11ac, it is Ubiquiti's own "AirMax" protocol. These devices can only connect to other Ubiquiti "AirMax" devices like LiteBeams, NanoBeams, PowerBeams etc.

Configuration Instructions:

LiteAP 120 sector standard configuration

The default IP of a factory reset unit is https://192.168.1.20/. Username: ubnt Password: ubnt

In Wireless set the following settings:

  • Wireless mode to Access Point PtMP airmax AC
  • SSID "nycmesh-xxxx-direction" (for exemple: nycmesh-1635-east)
  • channel width 40 Mhz
  • Control Freq. ON
    • Select all freq. and uncheck from 5565 to 5705 (5565 and 5705 included), as well as some other assorted frequencies. 
      • Just paste in the following, rather than doing manual checkbox selection:  5220,5225,5230,5240,5260,5265,5270,5275,5280,5285,5290,5295,5300,5305,5310,5315,5320,5325,5330,5485,5490,5500,5505,5510,5515,5520,5525,5530,5535,5540,5545,5550,5555,5560,5710,5740,5745,5750,5755,5760,5765,5770,5775,5780,5785,5790,5795,5800,5805,5810,5815,5820,5825,5830,5835

      • (This is extremely important. Due to FCC regulations in NY, we need to make sure to not use any channel overlapping 5590 - 5677)
