Terminal Signal weak – Accurate Pointing is Vital

It is vital that you point the terminal as accurately as possible.

Establishing a connection with the BGAN network requires the careful orientation of the BGAN terminal towards the satellite, a process called pointing. Accurate and precise pointing is important, because a badly-pointed antenna may mean you cannot register with the BGAN network, and will reduce the data rate achievable over the network.

To point accurately, ensure clear line of sight: obstacles such as buildings, mountains, trees and vehicles will reduce your signal strength. Also, be aware when pointing a terminal through a window that many windows in offices, hotels and so on have a metallic finish to the glass which will also affect signal strength. Where possible, position the terminal outdoors.

NOTE: During pointing, the location shown on the coverage map in BGAN LaunchPad is based on your previous location, or one that you entered yourself. The coverage map displays your current GPS position only after you are registered with the network. Your current city location only updates after you next register with the network.

NOTE: On the HNS 9201, if your terminal tries to register automatically on start up, you may have automatic registration configured. If you have moved your terminal since you last registered, turn off automatic registration, and re-point the terminal manually.

What is the minimum signal strength I require for registration?

The typical minimum signal strength required to register on the BGAN network is as follows:

HNS 9201 49 dBHz

Thrane & Thrane   EXPLORER 300, 500, 700  46 dBHz

Nera WorldPro 1000/1010 41 dBHz

If you are connected to BGAN LaunchPad, check the signal strength on the status bar.  You can also use the LEDs or the display on the terminal to monitor signal strength. The amount and type of information provided depends on the terminal.
