There is a massive gap between "Long term RF exposure can cause cell behaviors that may have subtle effects" from the paper you linked and "Hacked cell infrastructure can be weaponized" as the parent poster was claiming.

I'm an IT nerd, not a molecular biologist, so I can't really comment on the paper in detail but a quick skim gives me the impression that whatever effect they're measuring is both subtle and generally not directly linkable to the kind of effects a person would actually notice.

Something that could be used to cause targeted injury would have to be multiple orders of magnitude more powerful. The most effective way to weaponize hacked cellular infrastructure would be accessing the data traveling over it, not a fantastical idea of turning it in to a RF blaster.
