What is a passing DAQ score?

Most jurisdictions require a DAQ score of 3.0 or higher (on a scale of 1-5), meaning communications are understandable with repetition rarely required.

How is DAQ different from RSSI testing?

RSSI measures raw signal strength while DAQ measures actual voice quality. A location may have adequate RSSI but poor DAQ due to interference or multipath.

Does DAQ testing require public safety coordination?

Yes, we coordinate directly with local public safety agencies to conduct testing on their frequencies, typically during low-activity periods.

DAQ Testing

Delivered Audio Quality testing to verify voice intelligibility meets first responder communication requirements.

(888) 508-3001 ext. 2002

Overview

DAQ (Delivered Audio Quality) testing measures the actual voice intelligibility of radio communications, not just signal strength. This is the gold standard for ERRCS testing as it verifies that first responders can actually understand each other during emergencies. Our certified technicians perform systematic DAQ testing using standardized word lists and scoring protocols.

Typical Pricing Range

Most daq testing projects fall in the range of $2,500-$10,000+, depending on building size, access conditions, AHJ requirements, and whether remediation is needed.

Who Needs This Service

Buildings in jurisdictions requiring DAQ testing (California, Florida, many others)
Facilities where RSSI testing shows marginal coverage
Buildings with complex RF environments (hospitals, data centers)
Property owners seeking the most thorough compliance verification
