It’s a problem with Canonical. They stepped up and created the snaps and then abandoned them instead of maintaining them. They still maintain the core that they include with the distro… it’s all the extras they created to pad out the store… and then abandoned. “Look the snap store has so many packages”… yeah… no… it doesn’t.
Why would a company who makes a commercial level open source package want to add snaps to their already broad Linux offering? They typically already build RPM (covering RHEL, Fedora, openSUSE, Mandriva, etc.) and DEB (covering Debian, Ubuntu, all Ubuntu derivatives, etc.)… and have a tar.gz to cover anything they missed. Why should they add the special snowflake snap just to cover Ubuntu which is already well covered by the DEB hey already make?
Sure, show vendors what’s possible, but if Canonical stepped up to make the snaps, then they should still be maintaining them. It’s not a business opportunity… its more bullshit from Canonical that no one wants.
Generally, you use the radio network from mobile phone to cell tower, and then fibre optic to the switches. Sometimes they use microwave line of sight for surface-to-surface connections where fibre doesn’t make sense, or is unviable (terrain, distance, cost, difficulty of laying fibre, etc.). It’s possible that there could be a satellite connection in the process, but unlikely unless you’re on an airplane, a ship, etc.
The GPS on the mobile phone definitely does use satellite (receive only though, no transmit).
