Being excited to have my Part 107 Remote Pilot exam passed and Certificate applied-for, I was just scouting a downtown location in a neighboring city where a company wants to hire me to shoot their property. There were no significant issues with the location or with pedestrian and vehicular traffic close by...BUT... I pulled out my trusty WiFi Explorer phone app and discovered a gizzilion (oh, AT LEAST that many!) wifi signals in the immediate area. These were spread across the whole range of 2.4GHz, from 2.412 to 2.484, with a few sneakers coming in and out. There are lots of medical offices in the area and no doubt they communicate all the time, though it was only a little after 8 a.m. Okay, so I use a Phantom 3 Advanced and the user manual states on page 55 that my remote controller operates at 2.400 to 2.483GHz. As you can imagine, I am very hesitant to do this photo job. No way will I risk loss of control and whatever follows. I have never had a flyaway and don't want to begin that. Here is the Question: Are these concerns well founded? That is, is radio interference really likely and predictable?
