How to determine if a BDA System is beneficial to your building

Typically performed by specialized FCC GROL certified technicians and some fire department radio personnel, an RF Survey is accomplished by measuring the Downlink/Uplink signal strengths in decibels-milliwatts (dBm) using special measuring devices. Results are submitted to AHJ to determine if a BDA system is required or if a waiver is appropriate.
