Source: Date:

AT&T is accelerating its efforts to eliminate subway dead zones throughout New York City, and the latest upgrade focuses on the G train. In collaboration with Boldyn, a global leader in shared communications infrastructure, AT&T has launched 5G service along the G train route between Court Square in Long Island City, Queens, and Bedford–Nostrand Avenue in Brooklyn.

The rollout of 5G on the G line marks another major milestone for AT&T’s underground network expansion. Following the recent activation in the Joralemon Street tunnel—connecting Bowling Green in Manhattan to Borough Hall in Brooklyn for the 4 and 5 trains—AT&T continues to be the first carrier providing high-speed 5G service in these critical transit corridors.
