The New York City Subway 2015: 21 lines

469 stations

660 miles of track

Spotty cell signals

The Subspotting project captures, maps and visualizes the available cell phone reception in the entire New York City Subway up until beginning of 2017.

Over a period of two weeks in fall 2015, the Subspotting project logged the cell phone reception of New York City’s four major phone carriers along all 21 lines, 469 stations, and 660 miles of track covered by the MTA.

The result is a historical portrait of the electromagnetic fields of New York City’s underground – a map that highlights the system’s dead spots, stretches of spotty signals and available pockets of connectivity.
