In the movie, they were beat by exactly that: microwave towers.
satellite with an altitude of about 1 million feet (200 miles) is about 1230
satellire-to-satellite communication
Some of problem is hopcount... the RF-electro-RF and optical-electro-optical conversions between domains at the repeaters takes time. Such that one sat hop could indeed be faster... tradeoffs are sync and tracking of low flying birds vs geostationary delay distance. Today's subsea are using doped optical pump amps but still needs regen to avoid distance goo. HFT need reliable, low latency, non corrupt... trade ticks not necessarily high bandwidth movies. Worth a look to see if they ever used zero hop ELF RF. And if anyone has any legit outlook on quantum-RF.
