HFT have installed microwave relays between Chicago and New York and between London and Berlin to arbitrage on the 47% fiber optic delay between the exchanges. A LEO satellite relay serves the same purpose. I can see London to New York, New York to Tokyo fiber connections being superceded by LEO satellite.

- Tuna-Fish 6y agoLEO sat constellations that are low enough to beat existing solutions need to be almost global to provide reliable communication anywhere.
- kaliszad 6y agoIf you mean Deutsche Börse AG, than that would be Frankfurt am Main and not Berlin which is a slight difference of about 400 km. Frankfurt to London is actually a shorter distance. https://en.wikipedia.org/wiki/List_of_stock_exchanges https://en.wikipedia.org/wiki/List_of_stock_exchanges
