Testing the Data Service
With the PC connected to the "Data" port on the BDE open a browser on the Windows computer and
attempt to connect to http://speedtest.iridium.com. Once the site is visible click the "start" button. This
is a customized speed test that accurately measures the performance of satellite communications. Satellite
communication differs from terrestrial communications. In transitioning from stand-by to full load about
20 seconds are required to acquire the network resources. The speedtest tool has been specifically designed
to account for these characteristics.
Note the speed should typically be within 20% of the provisioned rate. While checking a 128kbps link note
that local activity may have the effect of slowing the link. This is not an issue at the sea since the use density is
significantly reduced over that of a major port. Seldom are the lower provisioned rates affected by traffic. If a
rate is out of specification wait 5 minutes and try again.
Now that the site survey, voice call, and data call have provided nominal performance you can initiate routine
use of the terminal.
