Signal boosters amplify and extend public safety radio frequency and cellular signal coverage capacity inside public and commercial buildings. Our team of certified technicians, engineers, and sales experts can help guide you to the right solution. We can design, install, certify, and re-certify indoor wireless communication systems and ensures they comply with International Fire Codes.

Will Your Building Pass A Wireless Signal Test?

Radio signal tests are routinely performed by fire inspectors to make sure commercial and industrial buildings have adequate wireless system coverage for public safety.

A certificate of occupancy permit will not be issued if the building fails this test.

Why Are Signal Tests Important?

Following the 9/11 terrorist attack in 2001, International Fire Codes were updated to ensure first responders could access radio frequencies from any commercial building in an emergency.

Emergency responders rely on these public radio systems to communicate with dispatch and each other if their own radio signal fails.

When Should Buildings Be Tested?

New building radio tests can be performed once the building’s core and shell are completed and all windows and doors have been installed.

For existing buildings, radio coverage should be retested annually and retested if local authorities change radio frequencies or update their system.

International Fire Code (IFC) 510: IFC Emergency Responder Radio Coverage Requirements

International Fire Code (IFC) 510 and the National Fire Protection Act (NFPA) 72 require all post 9/11 commercial buildings to have radio coverage or a radio enhancement system.

Public Safety DAS

Public Safety Distributed Antenna Systems (DAS) provide in-building emergency radio coverage to first responders.

A public safety DAS system often has these critical components:

  • The Donor Antenna receives the signal from public safety radio system
  • A BDA (Bi-directional Amplifier) amplifies those signals, and then evenly distributes the amplified signals via the Distributed Antenna System (DAS).
  • The DAS is the in-building network of coax cables, splitters, antennas
    • In larger facilities, DAS will be designed using fiber to avoid signal loss over long distances
  • The Battery Backup System ensures that the system operates in the event of power failure

Cellular DAS

Large-Scale Signal Coverage

A cellular booster is not enough to enable wireless connectivity throughout campuses, corporate headquarters or large buildings. Any building that occupies 250,000 square feet or more requires:

  1. A Bi-Directional Amplifier (BDA) to bring in signal from the outside.
  2. A Distributed Antenna System (DAS) to evenly disperse that signal through the building and/or campus.

Commenco partners with the leading equipment manufacturers to ensure campus and/or building-wide coverage for you, your employees, your tenants and your customers.

Reliable Service in an Always-On World

Cellular DAS manufacturers understand the issues and are constantly finding solutions to meet the market demand. Commenco understands your needs, and our experts are well-versed in the newest and best technology. Together, we make sure your new communication system is optimized for your building or campus’s unique specifications.

Cell Boosters

Cellular signal reliability has become a service as basic as water and electricity. The ability to use a cell phone to make a call, send a text, check email, or follow social media channels is an expectation. Just like all basic services, we expect our cell phones to work everywhere, including inside every building we enter.

Will customers return to a restaurant, store or entertainment venue and spend their money if they cannot use their cell phone while they eat, shop or play? The last thing that companies want is to drive customers away with poor or no cell coverage. After all, customer retention is vital to your business stability, and so is digital engagement. Businesses will miss out on opportunities such as social media geo-tagging and posting if they fail to provide adequate signal coverage.

Cost-Effective Coverage for Mid-Size Properties

Three to five years ago, most businesses either found that their cellular carrier couldn’t do anything to help them or that the options for enhancing signal coverage were too costly. Even today, most carriers will not support mid-size structures – but we will.

Commenco installs and maintains leading cellular signal booster technology, also known as passive DAS, at a far more affordable price than the leading cellular carriers. Cellular boosters fix poor cell coverage in any structure under 250,000 square feet by amplifying the incoming signal.

Our technicians are more than capable of boosting coverage for:

  • Small businesses (10,000 square feet or less).
  • Commercial offices, shopping centers, houses of worship (10,000-200,000 square feet).

Commenco capabilities

Commenco has been a leader in radio-frequency and two-way radio solutions for over 70 years. No one has more experience with distributed antenna systems and bi-directional amplifiers (DAS/BDA) than our team of experts.


Although most ordinances only require testing on newly constructed or modified buildings, the safety of our first responders should always be a priority.
