FCC Part 96 rules require that applicable CBRS Devices (CBSDs) be professionally installed. A Certified Professional Installer (CPI) may physically install the CBSD her/himself or may take the responsibility for accuracy of the data entered into the CBSD by another installer. All Category B CBSDs require CPI. Category A CBSDs installed above six meter Height Above Average Terrain (HAAT) and unable to selfgeolocate also require CPI.
