Canadian Telcos Agree on WiFi Hotspot Standard

Jucius Maximus writes "As reported by Globetechnology, Canada's cellphone providers have agreed to create a common standard for their subscribers to connect to the Internet via public "hot-spots." The agreement became necessary because Canada's cellphone providers offer four different and incompatible connection technologies. The carriers will continue to vigorously compete with each other, both for customers and Wi-Fi hotspot locations, the CWTA said in a statement."

3AM from people who say things like "What the @#$%!! Stop calling this number you @#$#tard!" or "Hello? Hello? STOP CALLING ME YOU PERVERT!"

Maybe your cellphone has been cloned. That would explain the huge bills and these calls. Have you ever asked for a listing of the calls made with your phone?

where energy comes in intensity distributions, not levels

But that's my point and that's what people don't often understand when it comes to matters of radiation.

Intensity does not matter because

Damage(E) = Intensity * Damage per photon(E)

If the energy (E) is too low to disrupt the DNA, "Damage per photon" goes to zero.

A (high) school physics example of this is the photoelectric effect in which the incoming photons extract electrons from metals. If the energy of a photon is less than the energy between a free electron state (=ejected electron) and a binding valence state (=electron in an atom), electrons do not get ejected no matter how intense your radiation is. You can replace the free-electron - valence electorn bandgap with the energy required to disrupt the DNA and the same reasoning applies.

The energy does not "accumulate" in the system either. The photon will only yield its payload of energy to the matter IF the payload is equivalent to the energy gap. Otherwise the interaction is negligible.

It's well documented that natural temperature variations in the brain are larger than anything induced by a modern cellphone.

The only way that I can imagine the cell phone radiation causing damage is an extremely unlikely chance of a interference peak of several fields inside the skull cavity. But even that would be short-lived because of the extreme sensitivity of the interference pattern on the dimensions and spatial location of the skull and the transmitters.
