I'm curious of the extent to which HFT is driving improvements in microwave network technology that are also becoming available to small ISPs and consumers.
As someone who works from home via a microwave link from a rural area I've definitely noticed improvements over the last few years as the dishes have gotten smaller and service faster and cheaper, far outpacing the rate at which phone or cable companies upgrade their limited service in the area.
Signal/noise issues would favor a low power omnidirectional emitter placed near a receiving dish, roughly in the known signal path. It could overwhelm the real signal by favorable inverse square intensity. Put the emitter on a drone.
At the time I posted it, the title on HN was in all caps (HFT IN MY BACKYARD - PART VI). Now it isn't thanks to a kind moderator. Must I be downvoted to -5 just because thanks to my own comment it is no longer necessary? Seriously, HN some days......
