What does this mean for amateur radio? A lot,
because it's the first time that radio amateurs don't have special
exceptions or exemptions in some way. They existed because of the
almost infinite number of situations and supposed 'solutions' in most
amateur configurations. The use of a truly online calculator (or one
that says it's "online" but is downloaded and run locally in a
spreadsheet or as a local executable) simply CANNOT in any way model anything but the simplest of situations. Parodoxically, it means nothing
except for a "warm fuzzy feeling" that the FCC, Ofcom, etc. have done
something to address an oddity in the use of parts of the radio
spectrum. So, go through the motions to the best of your ability, stash
away your results and get on with things. Just hope that they don't
tighten things further in the forseeable future. Field modelling is
sophisticated and expensive in time and money. It's sad that 5G is what
triggered these changes because of exposure on 'social media' and bad
press. Before this, few people thought of RF Exposure except for cell
towers being placed at or near schools, which was mostly 'folly'.
