Wall street tries shortwave radio [News]

In 2010, the company Spread Networks completed a fiber-optic cable linking two key trading hubs: Chicago and New York (or rather New Jersey, where Wall Street has its computerized trading equipment). That cable, built at a cost of some US $300 million, took the most direct route between those two points and shaved more than a millisecond from what had formerly been the shortest round-trip travel time for information: 14.5 milliseconds.
