I dont think it’s making any claims, for or against, other EM frequencies. It’s just that their study was specific to Wi-fi, so that’s what they’re reporting on

I dont think it’s making any claims, for or against, other EM frequencies. It’s just that their study was specific to Wi-fi, so that’s what they’re reporting on. Maybe they chose wifi in particular because it’s more relatable to the common person and quite ubiquitous on its own. They could draw more expansive conclusions in the future, if they want to. Or other curious scientists can pose that question and design an experiment / meta-analysis to answer it.
