why choose PMC wireless

public safety DAS & BDA solutions

PMC, an industry leader in RF design, implementation, and ongoing maintenance employs a dynamic team of experienced Project Managers, Engineers, and Service Staff to make your BDA/DAS project a success. Many of these projects are time-sensitive public safety initiatives, so choosing the wrong company can be devastating to your project timeline. From initial RF testing to full-scale DAS system implementation and acceptance, PMC has the personnel and know-how to get the job done right the first time and keep the in-building wireless system functioning throughout its life cycle.

At PMC, First Responder communications systems have been our focus for over 35 years, so we understand that an in-building Emergency Responder Communications Enhancement System (ERCES) can be a necessity when it comes to ensuring adequate communications when needed most. Trust in our experience and reputation to guide you seamlessly through the public safety DAS compliance process.

While a BDA/DAS system is a necessity in a lot of cases, it is very important that you qualify the need for the enhancement. Our first step in the process is to validate whether a system is, in fact, necessary. Steps need to be taken accordingly to ensure that the macro (outdoor) RF system being enhanced is not negatively impacted by the system installed to enhance it. PMC has strict guidelines when engineering DAS solutions so that these systems function properly. Any ERCES system will add to the RF “noise” in the environment where it is located, so taking steps to limit the impact of this “noise” is a necessity. PMC has the Personnel, Knowledge, and Processes in place to be your partner of choice whether you need a Public Safety DAS or Cellular DAS.

In-Building Coverage Test

In-Building Public Safety Coverage

ERCES emergency radio system Providing radio coverage for First Responders in both public and commercial buildings, as well as high rise residential structures has become part of building codes in most municipalities in the areas we serve. Since PMC has been designing and implementing Public Safety Radio systems for so long, providing these indoor coverage enhancements is second nature. Our licensed staff stays up-to-date with all national codes and local coverage requirements for in-building wireless signal coverage as established by the FCC, NFPA, and IFC.

PMC provides custom-designed Emergency Responder Communications Enhancement Systems (ERCES) or Emergency Radio Communications Systems (ERRCS) to ensure reliable two-way radio communication for first responders during emergencies. These Public Safety DAS solutions extend dependable coverage to hard to reach areas such as stairwells, underground tunnels, parking garages, electrical closets, and pump rooms, keeping communities and first responders safe.

Nearly every Distributed Antenna System solution is custom-designed for each unique environment. Variables that arise such as building materials, dead spots, signal interference offer specific challenges for comprehensive wireless coverage, we have extensive experience deploying and maintaining in-building wireless systems that overcome these challenges and allow customers to meet or exceed their local mandates.

Most municipalities require testing to verify sufficient public safety radio signals exist in new construction buildings (excluding private homes) before issuing a Certificate of Occupancy. This requirement also applies when permits are issued to existing buildings. Additionally, many municipalities require annual testing and necessary system upgrades for PS-DAS facilities to remain compliant with local mandates and inspection standards.

Wireless in-building signal coverage requirements are based on national codes established by the following organizations:

Federal Communications Commission (FCC)
National Fire Protection Association (NFPA)
International Fire Code (IFC)

Local Authorities Having Jurisdiction (AHJs), like your local Fire Marshal, may have additional requirements related to their specific wireless coverage needs. It can be overwhelming to navigate these ever changing requirements. Partnering with a trusted expert, like PMC Wireless can alleviate the confusion and stress associated with compliance, making the process smooth and manageable.

Custom Cellular DAS and BDA Solutions for In-Building Wireless Connectivity

No Cellular Coverage – Dropped Calls – Slow Internet Access – Frequent Website Buffering – Long Up-Load / Down-Load Times

At the very least these types of wireless connectivity challenges for cellphones, tablets and laptops can be frustrating, but if you are trying to run a business slow or inadequate cellular coverage can be disruptive and expensive.

With the influx of wireless technology that is dependent upon cellular coverage, providing adequate carrier coverage and capacity has become essential for many public and private enterprises. In addition, access to cellular coverage in challenging areas such as stairwells, parking garages, tunnels, and underground floors can not only be disruptive to productivity, but the lack of adequate coverage can be a significant safety hazard.

That’s why many facilities install Cellular – Distributed Antenna Systems and Bi-Directional Amplifiers to boost wireless coverage, so people can feel confident that they will always have reception when they need it most. BDAs operate within a Distributed Antenna System (DAS), and together, BDA/DAS equipment is often referred to as an in-building signal booster.
