Enhanced Emergency Communications

BDA System Installation for Florida Commercial Buildings

Maximize safety during an emergency by providing reliable communication. When in-building radio signals fail, AT&I public safety BDA systems keep first responders connected.

Help Prevent Injuries and Save Lives


Emergency responders often lose communication when in-building radio signals are weakened by strong structures. AT&I can provide a public safety BDA system to maximize the safety and well-being of everyone involved during an emergency.

Which Florida Buildings Need a BDA System?


Florida law requires all new and existing buildings to meet minimum radio signal strength for fire department communications, with limited exemptions. Dense concrete and below-grade levels are the usual reasons a building falls short, and these property types see both most often.

High-Rises and Condominiums

Concrete towers weaken the signal between upper floors and stairwells. Existing high-rises in Florida faced a January 1, 2025, compliance deadline under Section 633.202(18).

Healthcare Facilities

Shielded imaging rooms and basement service areas are common dead zones for public safety radio.

Schools and Campuses

Responders need coverage in every classroom wing and athletic building, since an emergency can unfold far from the front office.

Parking Structures

Underground and multi-level garages are among the hardest spaces for radio signals to reach. Buildings with underground areas fall outside Florida's small-building exemption.

Warehouses and Distribution Centers

Metal roofing and dense racking weaken the signal across large footprints. Facilities over 12,000 gross square feet fall outside that exemption as well.

If your building fits one of these categories, an RF grid signal survey shows you exactly where coverage stands.

What Can a BDA System Do for Your Business?


Understanding the NFPA Code

NFPA 1 Section 11.10.1 specifies that "In all new and existing buildings, minimum radio signal strength for fire department communications shall be maintained at a level determined by the AHJ." By adopting this requirement, firefighters, paramedics, and law enforcement officers will have more effective and reliable in-building radio communications. Florida enforces this through the Florida Fire Prevention Code and Florida Statutes.

Ensure Compliance

If your facility has adequate signal provided by the donor radio tower, your building may not require a radio enhancement system. Our trained and certified technicians use specialized equipment to measure radio signal strength within the building.

Failing RF Grid Testing

If a facility fails the grid testing, local fire officials will usually require that a radio enhancement system be installed to increase coverage where needed. We offer turn-key solutions to bring your building into compliance.

Florida BDA Compliance: Statute 633.202 and Fire Marshal Testing


Section 633.202(18), Florida Statutes, puts your local fire official in charge of the minimum radio signal strength your building must meet. If the interior falls short, that official can require a two-way radio communication enhancement system. That is the statute's term for a BDA or emergency responder radio coverage system. For a closer look at the law, read our guide to Florida's public safety BDA requirements.

Key provisions for Florida property owners

  • Existing high-rise buildings had to apply for a permit by January 1, 2024, and reach compliance by January 1, 2025.
  • Your local fire official can require a coverage assessment as often as every three years for existing high-rises and buildings over 12,000 gross square feet. Other existing buildings can be assessed every five years, and Level III alterations or a reported radio failure can trigger an assessment sooner.
  • Any new system or modification needs the express consent of the frequency license holder, kept on record.
  • Exemptions include buildings under 12,000 gross square feet with no underground areas, along with one- and two-family dwellings.
  • Once the system is in place, BDA testing and compliance inspections should happen every year, with results documented for your county or municipal fire marshal.

Our BDA System Installation Process in Florida


Every project follows the same four steps, so you know what comes next and what your fire marshal will review.

1

RF Grid Signal Survey

Our technicians divide your building into a grid and measure public safety radio signal strength in each section, including critical areas such as stairwells and the fire command room. The results show whether your building needs a system at all.

2

System Design

When the survey finds gaps, we design a BDA and antenna layout around your building's construction and your local fire official's coverage requirements. The design also accounts for the consent Florida law requires from the frequency license holder.

3

Installation and Acceptance Testing

Our team installs the donor antenna, bi-directional amplifier, interior DAS antennas and the connection to your fire alarm panel as one turn-key project. We then test the finished system so it is ready for the fire marshal review.

4

Annual Testing and Re-Certification

Each year, our technicians retest coverage and system performance. You receive documented results to support re-certification with your local fire official.

The Most Common Questions About BDA Systems


What is a BDA system?

A bi-directional amplifier (BDA) is a signal booster for public safety radio. A donor antenna on the roof captures the signal from the donor radio tower, and the amplifier carries it through antennas inside the building. Together, those antennas form a public safety DAS for commercial buildings, so responders inside can talk with command staff outside.

When does a Florida building need a BDA system?

Under Section 633.202(18), all new and existing buildings must meet the minimum radio signal strength your local fire official sets. Exemptions include buildings under 12,000 gross square feet with no underground areas and one- and two-family dwellings. If an RF grid survey shows weak coverage inside your building, the fire official can require a BDA system.

How does BDA testing work in Florida?

Testing starts with an RF grid survey that measures signal strength across your building. Your local fire official can require that assessment as often as every three years for existing high-rises and buildings over 12,000 gross square feet, and every five years for other existing buildings. Installed systems also need annual testing, with results documented for your fire marshal.

What is the difference between a BDA and a cellular DAS?

A public safety BDA amplifies first responder radio frequencies to meet Florida fire code, while a cellular DAS boosts carrier signal for the phones your tenants and visitors carry. Read more on our cellular repeater systems page.

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!
