Illinois, New Jersey, D.C.

These are the licensed microwave links that carry market data between the CME matching engines in Aurora, the exchange venues in New Jersey, and the Washington buildings where federal figures are released. MW and MM wave communications are often used in trading, due to an improved index of refraction over air versus fiber optics. Every path here ends at a real antenna on a real structure, drawn at the height the FCC has on file: ground elevation plus how far up the tower the dish sits.
