Why does it make sense? Are you afraid of tiny amounts of non-ionizing[0] radiation?
2.4Ghz is great for heating things at high power (my microwave outputs at 1200 watts), but the most powerful home routers only do about 0.2 watts. Cell phones can do about 1 watt, and you hold those up to your ear. In fact, it's been calculated that a year of wifi exposure is about the same as 20 minutes on a cell phone.[1]
And if non-ionizing radiation is anything to fear, you should be really afraid of the sun, which pumps it out at about 1000W per square meter[2].
