On the vessels LAN side the biggest challenge was to provide tickets with data quotas per month to the crew and insight in what is happening on the vessel when the connection is congested by video or other downloads with a high payload.
The second challenge was the cancellation of roaming. Since that has been cancelled in Europe, customers can benefit from larger data pools and thus higher data consumption. On the hardware side you need equipment that can manage the higher data throughput. That was not within the current solution.
