What exact model of Samsung Phones have this?
- plq 3y agoIt's just a regular 4G phone. They got LTE base stations up on the satellites. Actually, I'm not that surprised that they got the downlink working but I also would love to learn abut the challenges they faced while trying to receive a clean signal from a regular cellphone 600+km away. Cellphones' transmit power is severely limited due to a) proximity to human brain b) battery considerations. I imagine it also requires a clear view of the sky. That's how any satellite phone tech I ever laid hands on worked. I'd be astonished if they got it also working indoors. That'd be just pure magic. https://www.starlink.com/business/direct-to-cell https://www.starlink.com/business/direct-to-cell https://arstechnica.com/gadgets/2023/10/spacex-details-starlink-for-phones-plan-launching-in-2024/ https://arstechnica.com/gadgets/2023/10/spacex-details-starl... EDIT: Just to be clear, the link says nothing about the return channel but I imagine they wouldn't have made this announcement unless they got the return channel working as well.
