I wonder if buying shares of SLAM now is the same as investing in LYNK - assuming the deal goes through.I don't know much about SPACs, so its not clear to me what would happen to SLAM's $10 a share price if the deal goes through.
There are GEO based smartphone to satellite providers emerging now, using existing GEO birds. No idea about the technology, I can't imagine that any transmit on traditional smartphone frequencies, so they must use frequencies that some cellphones can access, but telephone companies don't use. This requires the satellite operator to have a license for that frequency in any target market. Maybe its the satellite to ground station downlink frequency.

The systems they already support are very low data rate and are specialized hardware, not smartphones. 3GPP to smartphones is "coming soon" and will require a firmware upgrade for the phone. Not sure how that will work, but it is highly unlikely to change the frequencies, and there should be no need to do so anyway. I will wait until they actually offer the product.

I will wait until they actually offer the product.If a GEO comsat could transmit in a frequency licensed by a cellular company for use by smartphones outside of cellular coverage, its very likely that the transmissions would interfere with terrestrial cell tower signal. That's a major no-no.I would guess that the GEO comsat would service cellphones via frequences outside licensed cellular bands, maybe L band.
But maybe enough for SOS and message?
