Neal, Sorry, I just can't let this one go. You are correct and to err on the side of caution is a good thing but let's put this in perspective. Considering that most of these stock devices are no more than +17 dbm (50 milliwatts) and that there will probably be 3-4 db or more of loss in the coax from the WiFi bridge to the antenna which brings the system down to 10db or less of gain (about 10x or 500mw/.5 watt) at the antenna and even if the someone is right against the antenna it is still putting out 100mw less than that cell phone everyone holds against their head which runs in the 1.9GHz band. The time domain microwave heating effects of 1.9 and 2.4 GHz on flesh are effectively indistinguishable. Phones are held against most heads for very long periods of time. Now I will go back and lurk for another year. S.
