Consider that higher frequencies produce higher effective transient
voltages in circuitry. At 50/60 hertz, there are many milliseconds fo the
voltage to rise. At 400 megahertz and up, it happens in nanoseconds. You
end up with higher voltages showing up in the wiring and the junctions.
That is one of the crucial ideas behind EMP weapons and shielding.
Also, while power lines have higher field densities than cell phones, they
are quite a ways from you and the inverse square law holds. The cell phone
can have a very low power output levelbut up close, it will utterly swamp
the power line signal.
Cheers!
