How to get the best ODU placement?

---

Factors to consider when choosing ODU location:

• Customer’s indoor router placement
  • 40m max cable run to Indoor Unit or PoE injector
  • Get as much height as you can
• Avoid obstacles, get best line of sight
  • Obstacles: buildings, walls, rooflines, metal, double glazing
  • Is there two chimneys? Pick the one closest to the signal
• Think about: height, reflections, obstructions

Tips for ODU installation:

• Use only SIM A slot
  • Ensure the SIM is sprung into place properly
• Use Eth 1 only for uplink cable, Do not use booted RJ45
• Use the signal strength indicators, which are the green LED lights on the unit
• Ensure the ODU door is closed and clicks into place

Pre-Alignment:

There are a couple of mobile phone apps that can assist with alignment by giving you an indication where to point the ODU:

1. Open Signal – Use the ‘coverage’ tab
2. Network Cell Info Lite – Use the ‘MAP’ tab

NB: You must be using a mobile phone with the same data carrier as the ODU. These apps provide a guide only.

First Alignment

• Connect the ODU to the Controller
• Check all compass points first and then begin to narrow down the optimum direction for signal
• Rotate slowly and pause for five seconds
• Find peak LED lights, then locate half way between the next best signal lights
• Login to the WiFi from the SimRush controller
  • The SSID is unique, “SimRush-xxxxxx”
  • The password is the Controller Serial No.
  • It is case sensitive, use CAPS
  • Use only the digits before the “/”

Fine adjustment

• Once WiFi is connected, web browse to: http://172.16.1.1
  • The screen on the right will appear in your browser with live graphs
  • You will need a laptop or WiFi AP for installing a SimRush Power or SimRush Core as there is no WiFi provided by these Controllers.
• Further detail is available by logging into the ODU
  • If you want to see the associated mast info then login
    • Username: installer (all lower case)
    • Password: Leave blank
  • Rotate slowly and pause for 5 seconds
  • SINR is the key indicator to watch, this needs to be as high as possible.
    • The higher the SINR level the better the service
    • A minimum of “+5” is required
