Dense Air and Millennium Parking Garages deliver breakthrough download speeds of 250 Mbps, transforming cellular connectivity underground

CHICAGO, Sept. 17, 2024 /PRNewswire/ -- Dense Air and Millennium Parking Garages are excited to announce the successful completion of a groundbreaking pilot project, aimed at enhancing cellular connectivity in challenging, hard-to-reach locations through seamless integration with AT&T and T-Mobile networks.

In early May, Dense Air and Millennium Parking Garages embarked on a unique partnership to transform Millennium Parking Garages into a test bed for innovative cellular network solutions. The collaboration focused on overcoming one of the most daunting challenges in connectivity: delivering reliable service deep underground through impermeable building materials.

We are thrilled to announce that our teams have delivered on their promise. By rapidly deploying the cellShare multi-carrier small cell solution, we successfully addressed the connectivity challenges in the underground garage. The project achieved continuous cellular coverage from entrance to exit in weeks vs. traditional solutions that are completed over months and even years.   

"We've tried before to improve cellular communications within Millennium Garages, but our partnership with Dense Air marks a significant step towards a scalable connectivity solution," said Issac Riggs, Chief Operations Officer, Millennium Garages. "They have given us confidence with their innovative design, rapid build, seamless integration with the carriers' networks, and most importantly, delivering exactly what they promised: a pilot testbed enabling seamless cellular connectivity."

To establish the foundational network in phase one, teams developed an efficient design and deployment strategy that ensured minimal disruption, a small footprint, rapid implementation, public cloud connectivity, and seamless integration with T-Mobile and AT&T. Millennium Parking Garages supplied the facility infrastructure, an enterprise network with a fiber backbone, a gigabit enterprise network circuit, and two micro server rooms with rack space to support the build of the solution. Dense Air then overlaid a cloud server for centralized management, along with other network elements, and deployed fiber-connected indoor radios for robust connectivity.
