As technology evolves, your retail store has the opportunity to bring a positive experience to your customers. But in order to support the increase in cellular traffic from customers and normal store operations, strong cellular connectivity in your building is vital to ensuring employees can communicate and customers can use their phones throughout the store.

Giving customers proper coverage and access to vital information like QR codes, interactive shopping lists, or simply making phone calls home to collaborate is a must. Shoppers used to blame their service providers for poor in-building cellular coverage, but now tech savvy customers are pointing those frustrations at the stores.


The National Fire Protection Association® (NFPA) and International Fire Code® (IFC) have codes in place to ensure first responder radios work in all parts of a building. Most states have adopted these codes and the local county Fire Marshal or Authority Having Jurisdiction (AHJ) enforce them. Building owners and contractors who do not meet the public safety code run the risk of delaying both the project and Certificate of Occupancy (CO).

There is a host of building materials such as concrete, metal, and low-e glass used in new construction projects that impede radio frequencies (RF) for first responders. RF testing can be performed to determine if a system is required to boost the first responder radio signals inside the building.

The importance of ERCES


DAS FAQs & Resources

Emergency Responder Coverage Enhancement System (ERCES) is the term used in Life Safety building codes to describe a system designed to enhance first responder radio signals inside buildings.   

There is a host of building materials such as concrete, metal, and low-e glass used in new construction projects that impede radio frequencies (RF) for first responders.   Most states have adopted building codes that are outlined in National Fire Protection Association® (NFPA) and International Fire Code® (IFC) to ensure first responder radios work in all parts of a building.   

An ERCES is composed of an external antenna (known as the donor antenna) that is aligned with a county radio tower (referred to as the donor site). The donor antenna connects to a bi-directional amplifier (BDA) through coaxial cabling. The BDA serves to amplify the radio signals traveling to and from the donor site. These signals are then distributed within the building also via coaxial cabling to a network of internal antennas, collectively known as a distributed antenna system (DAS) which are strategically positioned throughout the building to ensure comprehensive radio coverage for first responders. 

The local county Fire Marshal or Authority Having Jurisdiction (AHJ) requires building owners to comply with life safety codes outlined in NFPA and IFC codes for new construction and some existing buildingsThe AHJ verifies building coverage prior to issuing a Certificate of Occupancy (CO).   

Schedule a call with one of AWC’s seasoned ERCES professionals to conduct a radio frequency test within your buildingAWC uses specialized equipment to ensure your building meets the minimum thresholds for ERCES.  Based on test results, AWC coordinates with the AHJ on either a code compliant ERCES or exempt status. 

The AWC design engineering team can run predictive modeling scenarios based on a set of scaled floor plans and provide you with a budgetary quote to help you plan and budget your ERCES project.

Most jurisdictional codes are based on state adopted codesHowever, the AHJ has the authority to modify and adopt code at their discretionAWC has seasoned AHJ Code Compliance Coordinators to ensure your ERCES meets code and passes inspection.  

Every building is different and each jurisdiction has their own set of requirementsFor budgetary purposes only, it is recommended to use about $0.50 - $1.25/sqft to estimate the cost of an ERCES. 

No.  Code requires qualified, FCC licensed companies to design, install, commission, and test ERCES, based on requirements outlined in the jurisdictional coded enforced by the AHJ. 

Yes. Code requires annual inspections and proof of complianceAdditionally, ERCES require monitoring accessible via a port from your existing LAN or a cellular modem with annual plans attachedIn either case, check with your AWC sales professional to determine the best solution for your building. 

Building owners are ultimately responsible for ensuring state mandated Life Safety codes are met for the life of the building, even if the AHJ does not inspect your building.
