Do you have any use cases in the ocean (on board) in zoom app?
Unfortunately, there are no other companies with examples of onboard Zoom conferences via satellite communications (as of the end of October 2018).
Compared with the conventional communication with ships at around 128 kbps at the maximum, there is also information that communication services such as VSAT can realize data transmission of several Mbps class, and it is realistic depending on the actual usage environment and conditions. Throughput may not be as specified, but as mentioned above, the bandwidth required by Zoom will be about 1Mbps at the maximum, so I think that it may be usable.
I think that it is sure that you will actually use it on the ship, including confirmation of the operability and convenience of Zoom using a trial license, so please consider.
