Signal Boosters, also known as Bi-Directional Antennas - BDA, use a Distributed Antenna System (DAS) to extend the coverage range of radio systems (RF, Radio Frequency) in places where reception is bad. Usually businesses want BDAs to improve cellular coverage; however they are often mandated for first responder two-way radio operation. There is a big difference between Cellular BDAs and Public Safety BDAs and they should not be interchanged. Safety BDAs need to work under duress, such as high heat, chemical splash and no electricity. Cellular BDAs are for everyday use and not designed to work under duress.

Do First Responders have coverage EVERYWHERE in your building? We can let you know that. Give us a call at 866-797-0997 to find out how we can determine if a BDA is the best solution for you!

BDAs for first respondersTypical scenarios that need RF signal boosters are high rises, buildings that have underground floors, tunnels, subways, caves, mines and other difficult terrain where rescue is important. In recent years, many municipalities including Seattle and Bellevue WA require first responder BDAs, sometimes referred to as Rescue Lines for any new or renovated buildings. It is crucial that first responders are able to communicate via their radio frequencies in an emergency.

The components of a system are Donor Antennas, which capture the outside cell signal and send it down to the Bi-Directional Amplifier (BDA). The amplifier then distributes the signal to Internal Antennas. The most common method of connection between the devices is coax cable. This is the easiest method for splitting the signal to multiple antennas by using Taps or Splitters. These systems are capable of handling multiple signals of carriers. There are no environmental requirements for this equipment.

Being based in the Boston area, KTS is a contractor that installs building cellular repeater solutions to building owners and tenants alike. A strong cell signal is crucial aspect of a successful business today. Whether it’s employees or customers, the mobility of today’s society and workplace necessitates these systems. In the construction of new buildings and the renovation of existing ones, a building design that enhances the indoor environment while protecting the natural environment is what the Leadership in Energy and Environmental Design (LEED) rating system, developed by the U.S. Green Building Council, encompasses. The LEED system promotes sustainable buildings, awarding points for reducing energy use, improving indoor environmental quality and promoting a whole-building approach to sustainability. A major component of this certification is new energy efficient architectural glass. The components of the glass that make it energy efficient also make it RF and cellular inefficient by blocking the majority of signal from entering the building. A BDA system will be able to grab the signal from outside and distribute it throughout the facility. This technology is being mandated more and more across the country for first responders.

Several manufacturers of BDA systems and equipment are:
  • Laird Antennas
  • TXRX
  • Wilson Electronics
  • CradlePoint
  • Cellular Specialties
  • Cyfre
