Commercial Cellular Repeater Systems That End Dead Zones in Florida Buildings

Dropped calls, dead zones, and tenant complaints about weak signals cost your building productivity and goodwill. AT&I designs commercial cellular repeater systems that deliver strong, reliable coverage inside, so tenants, employees, customers, and guests stay connected on every floor.

In-Building Cellular Solutions That Bring the Networks Inside Your Florida Building


Eliminate dropped calls and lagging internet, and improve cell reception with a cellular repeater system.

Cellular repeaters keep patrons connected by bringing signals from the outdoors into the building, negating the attenuation of RF signals caused by the building materials.

What Can a Cellular Repeater Do for You?


Eliminate Coverage Gaps

Most modern commercial buildings have cellular coverage gaps, but yours doesn't have to. Several factors impact signal strength by the time it reaches you:

  • Cell tower proximity
  • Exterior obstructions
  • The building itself

Not being connected can raise stress, reduce productivity, and slow transactions. Wi-Fi systems help, but they are not a substitute. You need both.

Improve Your Building's Cell Connectivity

A strong, reliable cellular signal throughout your facility benefits people and operations:

  • Stay connected: keep employees, customers, and visitors able to take care of business
  • Convenience: make it easy for customers to access information and enhance their experience
  • Safety: enable everyone to reach emergency services if needed

How It Works

Every system starts with a site survey of your building's signal. A cellular repeater system is typically made up of three primary components:

  • A "donor" antenna, also called a reception antenna
  • A bi-directional signal amplifier
  • One or more rebroadcast antennas

Design to Implementation

AT&I works with your team and organization to design a commercial cellular repeater system that modernizes your building and keeps you and your customers connected at all times.

  • Site walk-throughs and product demos find the right solution for your organization
  • Pre- and post-installation support from our trained service team keeps you protected during the transition

Who Commercial Cellular Repeaters Are For


If people depend on their phones inside your building, weak signal is a business problem. AT&I designs in-building cellular solutions for Florida properties, from Miami and Fort Lauderdale to West Palm Beach and beyond.

Office Buildings

Office Buildings

Rebroadcast antennas distributed across floors, often called cellular DAS for office buildings, keep calls and mobile data working in interior offices and conference rooms.

High-Rises and Condos

High-Rises and Condos

Building materials that block outdoor signals leave dead zones in units, lobbies, and amenity spaces. A repeater brings coverage back.

Parking Structures

Parking Structures

Enclosed and below-grade levels stop being blind spots for drivers, staff, and security teams.

Healthcare

Healthcare

Staff, patients, and visitors stay reachable throughout clinics and medical offices.

Warehouses

Warehouses

Large structures get consistent coverage for the teams and mobile devices that keep operations moving.

Managing several sites? We design consistent coverage across multi-site portfolios.

Cellular Repeaters vs. Public Safety BDA: What's the Difference?


Both systems bring signal inside a building, but they carry different signals for different people.

Commercial Cellular Repeater

Boosts carrier signal for everyday phones, so tenants, employees, and guests can make calls, send texts, and use mobile data.

Public Safety BDA

Boosts first responder radio signals, so fire, police, and EMS can communicate inside your building during an emergency.

A cellular repeater does not satisfy fire code requirements for emergency responder radio coverage. If your building needs to meet code, explore our Public Safety BDA systems. Many properties need both, and AT&I can design each one for your building.

Commercial Cellular Repeater FAQs


Which carriers does a commercial cellular repeater support?

AT&I designs each system on the CEL-FI platform and confirms carrier coverage for your building during the site survey.

How many antennas does my building need?

It depends on your building’s size, layout, construction materials, and the strength of the outdoor signal. Some spaces need one rebroadcast antenna, while larger or denser buildings need several. The site survey determines the right number.

Does a cellular repeater satisfy fire code?

No. Fire code requirements for emergency responder radio coverage are met with a public safety BDA system, not a cellular repeater. AT&I designs both, so we can help you plan for code compliance and everyday cellular coverage together.

Is a cellular repeater the same as a cellular signal booster for commercial buildings?

The terms are often used interchangeably. Both capture outdoor signal with a donor antenna, strengthen it with a bi-directional amplifier, and rebroadcast it indoors.

Will Wi-Fi fix our cell reception problems?

Wi-Fi helps, but it isn’t a substitute for cellular coverage. Calls, texts, and mobile data on carrier networks still need a strong cellular signal, which is why most commercial buildings benefit from both.

How do we get started?

Fantastic service! James took my call and coordinated everything needed for our new gate system on the first call. He scheduled the install and the techs were on site bright and early. The techs Mark and Josh did an outstanding job on the install. From start to finish, I could not be happier with the experience.

It was approx 15 years ago was I first used AT&I at a property I worked at in Deerfield Beach. At the time my experience with most gate companies were far from favorable, but with AT&I I was amazed by their honesty. They are a great consistent group of decent honest people that do-good work period! I value and have trusted their input and service along the way, and will continue to do so, as they have yet to fail me. Thank you, AT&I Systems!!

They are always helpful on the phone and good about getting a tech out quickly when necessary.
Great bunch of folks to work with, we submitted a work request on Wednesday, and they were here on Thursday diagnosing the problem. Service tech was very knowledgeable and professional. We look forward to a long relationship with AT&I......Thanks
All the techs are great. Mark is outstanding . He can represent my company anytime. You, lucky to have him. 👍👍👍👍👍. Rich Fallon
ATI Security Systems is always prompt with service and their response time. Anytime we call or email for service, they usually send out a tech same day, when its possible. Our company has used them for our community gate repairs for years!
AT&I installed a new parking access system at an office building we mange in Doral. From start to finish it has been a great experience. They are prompt in replying, they show up when scheduled. Oscar, Brett and Dave are a great team and we are happy we selected AT&I for our new access system.
AT&I staff are real professionals. They held our hand during the implementation of GateKey and OpenPath. In our development, we love the simplicity of the GateKey entry system - it’s simple and intuitive to use. The OpenPath system allows our snowflakes to open the gates while driving a temporary rental car or as a passenger in someone else’s car. Great products and great team.

I have worked with James at ATI for my condo association with multiple gates and cameras. Before ATI, we were a mess. After suggested upgrades and replacements, we are finally running 24/7 with few glitches now in community. The problems we have had over past year were addressed promptly and properly. I have no doubt that no other company could do a better job.
Ricky Zalewski at AT&I is very helpful and extremely pleasant to deal with.
I have been working with AT&I Systems for several months now. They are very quick in responding to our access gate service calls. We will hopefully be contracting them to do all of our security cameras as well! I would highly recommend them. Brett W is awesome!
ATI and there staff are first class. They solve problems and give solutions. I’ve been a BOD and a licensed Property Manager. I’ve hired them at multiple properties and they’ve done an excellent job. I wouldn’t highly recommend Oscar Jon and Ricky for your South Florida gate needs. When the gate goes down or the call box has an issue just call or e-mail them for assistance. Bravo ATI. !!
Great Company. Troy Hildebrant was AMAZING. He came out and trouble shot our issue and had it fixed in no time!! Very knowledgeable, professional, dependable and kind. Would definitely recommend this company.

I have been dong business with ATI for years. Pricing and service are fantastic. Had an issue with alarm and security gates last week. Service tech's were out the same day and resolved all issues at a fair price. Would not use any other company!
It was a pleasure to do business with AT&I security systems. We called them in the morning and our gate was fixed in the same day. They have the nicest staff and their sales team is always eager to help. Their camera quality is superb and their gate systems are truly the best! Thank you Oscar and team!
