AT&T, in collaboration with Boldyn Networks (Boldyn), announced the launch of 5G cellular service in the Metropolitan Transportation Authority’s (MTA) Crosstown G train line segments. This marks another major milestone in the MTA and Boldyn’s ongoing effort in bringing high-speed connectivity to the entire New York City Subway system. AT&T riders traveling on the G line between Court Square station in Long Island City, Queens and Bedford–Nostrand Avenue station in Brooklyn, can now enjoy cellular service in tunnels.
This latest activation follows the recent go-live of AT&T service in the Joralemon Street tunnel, which serves the 4 and 5 trains lines between Bowling Green station in Manhattan and Borough Hall station in Brooklyn. AT&T, being the first carrier on-air for both the G line and Joralemon Street tunnel underscores the momentum of a strong collaboration in delivering universal subway connectivity for riders.
"Every new section we light up brings us closer to a fully connected New York,” said John Emra, president, Atlantic Region, AT&T. “By working closely with Boldyn Networks and the MTA, we’re helping ensure reliable, high-speed 5G is part of the everyday transit experience for New Yorkers. We’re proud to be the first and only carrier to deliver that enhanced experience to the G line.”
