How much brain cancer do Americans have to accept to satisfy agreements on "fair trade"? Anyway, it wouldn't be a matter of banning TDMA technologies So much as limiting specific absorption ratios per bit per second, for devices at particular frequencies, with 2GHz being punished severely, and tolerance shown to 800MHz and 450MHz. Because CDMA is better, other technologies would have trouble meeting regulations while providing good service to subscribers.

Europeans would understand the "precautionary principle", especially when the physics of radio frequency is that superposition of two waves gives higher energy than one alone, in the same way that two water waves combined can reach higher than either alone. Even a little wave boosts the big wave.

The question is how much brain cancer is caused, not whether any is caused. My guess is that it's such low level harm that it's not worth worrying about, but if there's any risk, then for no cost, people might as well use low frequency and low dose technologies. There is actually less cost with low frequency since propagation is so much better at low frequencies, meaning fewer base stations are needed and coverage inside buildings and other non-line of sight situations is better.
