Apparently the range is poor?
Whatever happened to the use of ELF to communicate with subs?
“ Apparently the range is poor?”
Poor is putting it kindly.

Line of sight, it’s got range, but it penetrates very little.
Yes. They have to use higher frequencies to meet the higher bandwidth requirements. Shorter ranges AND you need more antennas to cover everyone even if they aren’t trying to now live-stream via Periscope or have self-driving cars navigating via the signals.
It's designed for short range. Unlike your current phone, antennas will be directional and use nearby microcells. The architecture is fundamentally different.
