Connecting one of the world's busiest transit systems requires collaboration and long-term commitment New York City's subway system is one of the most demanding communica ons environments in the world. Millions of riders move through tunnels, pla orms and sta ons every day, expec ng seamless connec vity throughout their commute. Delivering that level of connec vity requires more than infrastructure alone. It demands long-term investment, careful coordina on, and trusted partnerships built to support a transit system that operates 24 hours a day, seven days a week. That's where the collabora on between AT&T and Boldyn Networks (Boldyn) comes into play. Working together, they have expanded AT&T cellular service across the New York City Subway system, most recently adding coverage in addi onal tunnel segments of the 4/5 lines and the Crosstown G line. AT&T is the first and currently the only carrier to connect and go fully on-air between these segments. These expansions help close coverage gaps and bring the system closer to con nuous underground connec vity. Boldyn's broader effort to extend connec vity across the en re subway system is well underway, with a phased rollout of a 5G distributed antenna system (DAS). Today, riders with major mobile carrier cell service have connec vity in the 42nd Street Shu le tunnel and the L line's Canarsie Tube, with major mobile carrier cell service and Wi Fi available in all underground sta ons. These milestones reflect steady progress toward a fully connected subway, delivering seamless connec vity across sta ons, pla orms, and tunnels, so riders stay connected throughout their journey. Why Connec vity Now Defines the Transit Experience From streaming content and staying produc ve to tex ng family and naviga ng the city, public transit riders rely on connec vity throughout their commute. As expecta ons rise, transit agencies increasingly treat wireless infrastructure as a core component of the rider experience, raising the bar for how connec vity must be designed, built, and operated at a system-wide level. Delivering connec vity underground is uniquely complex in always-on transit systems like the New York City Subway. Dense infrastructure, aging tunnels, ght spaces, and constant service demands require shared infrastructure models, long-term opera onal support, and close collabora on between carriers, transit authori es, and infrastructure providers. A Shared Model Built for a System‑Wide Network At the core of this effort is a shared model designed to support connec vity. This collabora on enables a reliable and growing network across one of the most challenging wireless environments in the world, moving the system closer to true end-to-end connec vity. Boldyn designs, deploys and operates the neutral host infrastructure across the transit environment, while AT&T deploys and integrates its network equipment to connect to that infrastructure and deliver reliable service across the system. FirstNet®, Built with AT&T is the only network built with and for America's first responders. And through FirstNet, public safety personnel have always-on 5G priority and preemp on to help them communicate and coordinate during emergencies across New York City. Achieving connec vity at this scale requires sustained investment. AT&T's recent $250 billion commitment to network infrastructure reinforces its focus on expanding connec vity in high-impact environments, including transporta on systems. Combined with Boldyn's infrastructure exper se, this long-term carrier investment enables con nued planning, deployment, and opera onal support across complex environments like New York City. Transit connec vity is not a one- me deployment, it is an ongoing effort that depends on partnerships aligned around long-term commitment and shared responsibility. A Collabora ve Model for Ci es Like New York The work underway in New York reflects a broader shi in how ci es approach transit connec vity. As agencies invest in wireless infrastructure across transit systems, venues, and public spaces, this long-term partnership model helps define what it takes to deliver connec vity at scale. Together, AT&T and Boldyn demonstrate how shared infrastructure and carrier investment can support reliable service across even the most complex environments. By combining neutral host deployment with na onwide network capabili es, the model offers a founda on other ci es can build on as they modernize their transit systems. As connec vity expands across addi onal subway tunnels and transit environments, the goal remains simple: ensure riders stay connected from the moment they enter the system to the moment they reach their des na on.
