Question 26C3
Element 9 (GMDSS Maintainer)Which of the following best describes Inmarsat BGAN Streaming Data service?
Explanation
Inmarsat BGAN Streaming Data provides a dedicated, guaranteed data rate connection. Unlike BGAN Standard IP, which is a shared, best-effort service, streaming data reserves a specific bandwidth slice exclusively for your terminal for the duration of the connection. This "exclusive, high-priority" characteristic ensures consistent throughput and minimal latency.
This guaranteed performance makes it ideal for "time-critical applications" where interruptions or delays are unacceptable, such as live video broadcasting, high-quality VoIP, or secure VPN connections.
Option A describes Inmarsat BGAN Standard IP, which is a shared service optimized for general TCP/IP traffic like web browsing, email, and non-time-sensitive file transfers. Option C describes a local interface, not an Inmarsat data service. Option D mentions ISDN, which is an older, circuit-switched technology; BGAN Streaming Data is an IP-based service designed for guaranteed bandwidth, not specifically ISDN.
