A Public Safety Emergency Radio Communication Enhancement System (ERCES) Distributed Antenna System (DAS) is a dedicated in-building network specially designed to provide reliable, uninterrupted radio coverage for first responders. 

It is also known as the Emergency Responder Radio Communications System (ERRCS). It ensures that first responders have consistent and robust communication capabilities, including land mobile radio signals, for firefighters, police, and other emergency personnel in critical situations. 

By delivering essential voice connectivity for public safety radio signals into hard-to-reach spaces, an ERCES safety-grade DAS allows first responders to execute missions that save lives during crisis situations where commercial networks routinely fail.

Public safety DAS supports land mobile radio frequencies for police, fire and EMS. It is designed to provide comprehensive coverage with clear and consistent voice communications for first responders everywhere in the structure. 

It is required by the National Fire Protection Association (NFPA) and International Fire Code (IFC) to ensure that first responders can communicate effectively in buildings and other structures.

Commercial cellular DAS, on the other hand, provides coverage in public-use areas and also enough data capacity for smartphone users. It is an ideal solution for large buildings, stadiums, airports, and other areas where there is a high concentration of people and wireless devices. 

Commercial cellular DAS is not required to meet the same standards as public safety DAS, but it is still an important solution for improving wireless coverage in commercial building.

An ERRCS is designed to ensure reliable communication for emergency responders in buildings and large facilities. It enhances radio frequency (RF) coverage for first responders, enabling effective communication during emergencies, critical incidents, or disasters. 

They are required by the National Fire Protection Association (NFPA) and International Fire Code (IFC) to ensure that first responders can communicate effectively in buildings and other structures. ERRCS systems can also help to reduce response times and improve overall safety.

Many local and national building codes mandate Public Safety DAS coverage inside medium to large buildings. Major national codes include:

• NFPA 1221 – Standards for installing equipment to sustain emergency responder radio coverage
• IFC – International Fire Code mandating 95% area radio coverage in buildings
• IBC – International Building Code also governing public safety DAS

These codes mandate complete in-building coverage with no dead zones at set signal levels, along with hardened system components with battery backup power and pathway survivability for resiliency.

• Reliable communication: ERCES systems provide reliable communication for first responders during emergency situations, ensuring that they can communicate effectively in buildings and other structures.
• Coverage in Critical Areas: Provides seamless wireless coverage in critical areas, such as stairwells, basements, and other spaces prone to poor signal penetration, ensuring that first responders can communicate effectively throughout the entire building.
• Improved Response Time: Reduces communication delays, allowing first responders to quickly assess and respond to emergency situations, leading to more efficient and potentially life-saving interventions.
• Compliance with regulations: ERCES systems are required by the National Fire Protection Association (NFPA) and International Fire Code (IFC) to ensure that first responders can communicate effectively in buildings and other structures.
• Improved building safety: Enhances the overall safety of building occupants by facilitating communication between first responders and building management, allowing for timely evacuation instructions and updates during emergencies.
• Compliance with Regulations: Meets regulatory requirements of local Authority Having Jurisdiction (AHJ) and codes that mandate the installation of dedicated systems to support public safety communications within buildings, ensuring that the facility adheres to local and national safety standards.

A Distributed Antenna System (DAS) is a network of antennas that are connected to a common source and distributed throughout a building or area to improve wireless coverage. The common source can either be a single bi-directional amplifier (BDA) or a system that consists of a headend, which is the central hub of the system, and remote units, which are located throughout the building or area. 

The headend is connected to the remote units via a fiber optic or ethernet cable. The single BDA or the remote units then distribute the signal to the antennas, which are strategically placed throughout the building or area. 

An emergency responder communication enhancement system (ERCES) ensures robust in-building radio signal strength for first responders.

• Passive DAS: Uses a single amplifier to utilize existing outdoor signal to boost and distribute it within a building. Cost-effective for smaller spaces with good outdoor signal.
• Active DAS: Uses a headend connected via fiber to remote amplifiers to significantly boost signal strength, ideal for large spaces or areas with weak outside signals.
• Hybrid DAS: Combines passive and active elements for customized solutions in complex environments. It offers a versatile solution for optimizing wireless coverage in large and complex environments by combining active and passive components, leveraging both coaxial and fiber-optic infrastructure to address specific challenges related to signal distribution and capacity requirements.

Installation time ranges from a few days for smaller passive systems to several weeks for complex active installations. We work efficiently to minimize disruption and deliver swift results.

The cost of a DAS depends on various factors, including size, type, and complexity of your location.
