The CPI certifies that the lat/lon, antenna height, azimuth, radio model and SN, and antenna model are correct as submitted to the SAS. Also frequency, channel width and EIRP, but you request those and the SAS grants them.
For CPE installs, if you know the lat/lon, you know the azimuth. In most cases someone at the office will provide the radio and antenna for the installer and will therefore be able to get that info. The requirements for horizontal and vertical location accuracy are loose enough that in most cases you can easily meet them without being on site, for example from Google Earth. If the physical installer is provided with a handheld GPS, and takes a cellphone photo of the install, it is reasonable for the CPI to verify and enter this information without having to be onsite. It is actually easier for new installs. We transitioned a lot of existing 3.65 customers to CBRS. I would say I had to go out and verify at most 10% of them because we didn’t have good records of exactly where on the property the CPE was installed. A couple I used a laser rangefinder to determine AGL, but mostly because I was there and I had one, it is honestly overkill except maybe for tower sites where you don’t know the exact height. If the CPE is on a customer’s TV tower, you can count 10 ft sections to get the height. IMHO, the new WISP owner should pay the money and take the time for the online course and exam. It’s not hard. He will learn some stuff about CBRS, and will have his own CPI credentials for adding and modifying data in the SAS, you really don’t want to be reliant on an outside contractor for this. In the grand scheme of getting CBRS working in your network, CPI credentials are a small piece. Just do it. He is using CBRS, right? Otherwise, this is all moot.

Somebody at that company really should do the certification, contracted CPI input just begs for a disaster years down the road. I cant see any CPI giving up their credentials to a non employer for SAS management. I know I wouldn't.
