Since I know (thanks to Bloomberg) that the country where I live (Belgium) is a very interesting place for High-Frequency Trading microwave towers (Belgium is in the middle of the London-Frankfurt network), I am working on a map of the different paths using radio towers to carry data between London and Frankfurt. I’ll publish a detailed map next week. In the meantime, here is one path I have reconstructed (here in purple), used by HF traders but owned by a technology firm leasing the network to them. There is one tower which is not included in the network. Is it what the industry calls “tower squatting”?
