Cellular Coverage Three Levels Underground
Park Fast, Dallas Arts District
Park Fast's parking garage in downtown Dallas sits three levels below ground, where cell signals don't reach. EV chargers, payment stations, and the people parking there all depend on a connection, so we designed and installed a cellular repeater system to bring AT&T, Verizon, and T-Mobile coverage underground.
At a Glance
The project in numbers
3 levels underground
Concrete and earth block cell signals almost completely below street level
70,000+ sq ft
157 parking spaces across three below-grade levels beneath the Atelier building in the Dallas Arts District
6 EV chargers
Charging stations and payment stations that need a working connection
3 major carriers
Coverage for AT&T, Verizon, and T-Mobile customers throughout the garage
The Challenge
No signal below street level
Underground garages are one of the hardest places to get a cell signal. Layers of concrete and earth stop it almost completely. For a modern parking garage, that's more than an inconvenience: EV chargers and payment stations need a connection to work, and the people parking there need to be able to use their phones for accessibility.
The Solution
Bring the signal down from outside
Surveyed every level
We started with an extensive site survey of the garage to see where signal dropped off and plan exactly where each antenna and repeater should go.
Placed antennas outside
Antennas mounted outside the garage pick up a strong signal above ground, where it's available, to feed the system below.
Ran conduit
We ran conduit to carry and protect the cabling from the outdoor antennas down through the garage.
Installed repeaters throughout
Cellular repeaters on the underground levels rebroadcast that signal through the garage for the best possible coverage on AT&T, Verizon, and T-Mobile.
The Results
A connected garage, top to bottom
- 01 Cellular coverage brought down into all three underground levels
- 02 Works with all major US carriers: AT&T, Verizon, and T-Mobile
- 03 A connection for EV chargers and payment stations that depend on it
- 04 Better accessibility for drivers and visitors parking below ground
- 05 Cabling protected in conduit, built to last in a busy garage
