Eli5: How can we beam unlimited HD satellite TV to billions of homes but satellite internet is objectively terrible?

1.84K viewsOtherTechnology

So, my parents livr in an area where the only internet available is satellite. It sucks.

However, they also have satellite TV and can watch that no problem.

What’s the difference? Is it just a scale issue where TV has more money and resources compared to satellite internet companies?

Broadcast television is sending one signal in one direction over a wide area. No special antenna hardware needed, bandwidth usage remains low.

Satellite internet needs to send and receive multiple, separate signals. All those individual signals have to compete for limited bandwidth (both in the radio spectrum and the satellite’s processing power), slowing down the service for everyone.

Starlink seems to have mitigated this problem by basically just throwing more and more satellites with special directional antennas at it. Seems to work, but expensive as hell and there’s still the problem of high ping since the signal has to travel a greater distance to space and back.
