While parking garages are known for having bad cell signals, there's now an easy solution available through the use of commercial signal boosters. Signal boosters do exactly what they sound like – they take weak signals and boost them across a large area and work across every level of a parking garage, including entrances, stairwells, ramps, and even the deepest underground bays.
Reliable cell signal keeps your facility safe, efficient, and convenient. It supports smarter operations and a better experience for everyone on-site.

Delivers reliable 5G and 4G multi-carrier coverage for up to 200,000 sq ft. Scalable and ideal for large factories, refineries, and production floors.

Up to 100,000 sq. ft. of reliable coverage with cloud monitoring and channelized design to avoid interference. Perfect for mid-to-large facilities.

Verizon-only C-Band booster supporting high-speed 5G for data-heavy manufacturing systems and IoT-driven automation.

Why is cell service so weak in parking garages?
Cell service is weak due to the size and material used for them. They're constructed using concrete, steel rebar, and below-grade construction blocks, which greatly attenuate radio signals; the distance and line-of-sight to nearby cell sites make it even tougher.
Will a booster work if the garage is fully underground?
Yes. By placing a donor antenna where a usable outdoor signal exists (roof or exterior) and distributing an amplified signal indoors with a properly engineered design.
Do these systems support multiple carriers at once?
Yes. Our enterprise solutions are designed to enhance coverage for all major carriers simultaneously. This will vary depending on the model capabilities and frequency availability.
Do we need fiber or new risers?
Not necessarily. Systems may use coax or Ethernet runs (e.g., QUATRA uses category cable to remote units). We evaluate existing pathways during design.
Can this address public safety radio coverage too?
Cellular boosters improve mobile service; public-safety radios use different bands and requirements. We can coordinate a separate public-safety DAS if your AHJ requires it.
What's the first step to get started?
The first step is to contact our team, either by phone 1-800-420-3211 or email sales@signalboosters.com, and we'll arrange a free consultation where we can discuss your needs and coordinate a site visit.
