4G/5G modem wired to bluetooth to tablet (underwater)

Hi,

My boss has given me the mission of trying to figure out of it's possible to run a zoom class underwater, as in one person is underwater with an ipad. We have the underwater ipad housing, which works fine. Audio is an issue, and I think for running it zoom through the ipad it's not going to be practical.

I know that wifi and bluetooth do not travel through water well at all. I gather from a bit of reading that you can get okay bluetooth connection within a couple of cm in seawater. So the idea would be to have a bluetooth unit, in a small housing, stuck to the back of the ipad housing.

So how easy would it be to find a 4G modem that can be wired to a bluetooth unit that can provide the ipad with internet, where the modem sits on the surface, the wire runs underwater to the bluetooth unit, which is in a waterproof housing.

We're exploring other options like running video from a wired gopro or similar, and audio from a separate unit, and joining them on a computer on the surface, then streaming that, but it'd be nice to know whether running internet to a tablet is possible as well.

Thanks for any opinions
