4g Vs 3g

WiFi transmit power: less than 0.1W Europe, less than 1W USA

3G/4G transmit power: 1 to 3.5W not in standby

3G/4G transmit power: 1 to 3.5W not in standby

Does this relate to a phone's SAR rating in any way ?

Meh, the body absorbs different frequencies differently. Wifi is a big one (same as the ones to cook food) but 4G also uses many close to that when you are outside of a building. It's more power and more spread out, so more chances of hitting many absorption peaks. Also you don't keep your laptop in your pocket...

Also 2.4Ghz isn't the best to cook, it's just the most viable.

Much as a I dislike Comcast, I wonder how much of an impact newer 'disruptive' technologies would have like:

high-frequency “millimeter” electromagnetic airwaves - sounds fun.

The new Wifi will use them too... good luck to that guy
