RF Benchmark Testing

Pacific DAS test reports are easy to read and interpret, and are suitable for presentation to the owner or AHJ.

Testing

Pacific DAS performs RF (Radio Frequency) Benchmark testing per California’s Fire Code-section 510 and NFPA1221, providing a calculable verification of wireless coverage in a building. Our FCC certified technicians use state-of-the-art test equipment to measure and record the current signal levels in the building, and the results are made available within 48 hours. These metrics are used as part of our design process to ensure radio signal enhancement is provided only where it is required.

What is the California Fire Code?

The National Institute of Standards and Technology (NIST), along with the U.S. Congress through FEMA, investigated building and fire safety after the tragic incidents of 9/11. The report listed several recommendations for updating. The International Fire Code (IFC), section 510, requires that “All new buildings shall have approved radio coverage for emergency responders within the building based upon the existing coverage levels of the public safety communication systems of the jurisdiction at the exterior of the building.” It states that “The building should be considered to have acceptable emergency responder communications enhancement system coverage when signal strength measurements in 95 percent of all areas on each floor of the building meet the signal strength requirements.” These signal strength requirements can vary between jurisdictions, some will require a Delivered Audio Quality (DAQ) of 3.0 or better while others will also require a signal strength of -95dBm or better, some require both.

When Do I Test My Building?

All new construction requires an ERRCS test to be completed when the building has reached substantial completion. Generally, this means that all the windows and doors are installed, and the roofing and exterior wall finishes are in place. Pacific DAS can also offer preliminary testing earlier in the project that can help with the planning process.

What are our FCC Certified Technicians Evaluating?

• Inbound Signal Strength
• Outbound Signal Strength
• Noise floor
• Delivered Audio Quality (DAQ)
• Donor Signal Sources

What is the Testing Process?

• Each floor is divided into 20 grids
• A test is conducted using a calibrated spectrum analyzer and a portable radio to measure the signal strength in each grid
• General areas must have 95% coverage and critical areas must have 99% coverage.
• If two or more of the grids fail, the floor fails
• If one floor fails, the building fails, and coverage enhancement will be required
• A report will be made and sent to the building owner or contractor
• If the building passes the test, then there will be no need to install a system
• If the building fails the test our team will be happy to work with you on the next steps
