Aeronautical VSAT & Terestrial Interface Commercial airlines are rapidly discovering the advantage of in-flight connectivity. It’s absolutely essential to compete for the loyalty of more than one billion people who travel each year. And it’s critical to improving operational productivity in an industry constantly facing rising costs.
While the concept of in-flight connectivity took decades to get off the ground, the technology is taking firm hold today. Nearly every major airline has rolled out, or is planning to install, some form of in-flight connectivity service. The other primary solution for in-flight connectivity is VSAT, which is rapidly being embraced by airlines. With VSAT, airlines are able to offer higher data rates, with continuous coverage for both domestic and international routes. To linking with VSAT, we have several products to interface from IP VSAT network to almost any ground communication facilities (voice & data).
