1800 symbols per second is the benchmark for shortwave data transmission.

Not sure exactly how useful that would be, but the latency is low: 0.01 seconds to cross the width of the USA.
A round trip packet from NY to SF takes 0.05 seconds, a fifth of the speed. Fibre is quick, but not as quick as radio.
There’s about 1400 bytes usable in a TCP packet, versus the 1800 symbols per second over shortwave. Lots of TCP packets can be exchanged per second.
I don’t see the value proposition.
That’s plenty of data to trade on. If you believe in efficient markets the priced should be more or less the same globally, you can make a lot of money if you know what the market price in Tokyo should be because you know the price in NY first, or vice versa.
