Vessels equipped with Vsat communication face challenges due to expensive and limited bandwidth. Typical speeds are 128-256kbps, which is shared among crew personal computers and laptops. Multiple simultaneous users can reduce bandwidth availability. CrewCommCenter addresses these issues through an optimized web browser that reduces data usage by 70% and a "thin" chat client that uses minimal data. This provides improved internet access for crew while preventing bandwidth-intensive activities and securing the connection through dedicated ports and firewalls.
