The World wants broadband connectivity…
» The world is in the "cloud" and
everything is connected
» In the next 5 years data traffic
will triple and Mobile data traffic
will increase 10 times

… from everywhere …
» Terrestrial Line Of Sight systems are limited to small
areas and affected by orography
» This aspect is critical for
large areas and aircrafts
and ships that can travel
large distances and for
systems in remote areas

Summary
» Satellite communications have entered in the broadband
curve and are an option to cable and ADSL connectivity
» Satellite networks can allow the deployment of high
speed connectivity on large underserved areas (South
America, Africa, …) or on emergency situations
» Mobile/portable SatCom terminals enable broadband
experience for nomadic & mobility applications
