Time Averaging Erases RF Peaks


by Amy O’Hair


With modern technologies which can produce a transmission pattern of millisecond pulses–and all smart meters and cell phones do this–a device can emit pulses which at their peak far, far exceed the FCC upper limit,yet when averaged will appear to comply with it, even be far below it. One EMF technician associated with Stop Smart Meters! during his preliminary data gathering has recorded a peak pulse in excess of 20,000 µW/cm² (=200W/m²) and observed ones far higher than this.

Time-averaging is how PG&E
hides the true peak levelsof RF pulses produced by their smart meters. This chart below shows the stark difference between averaged (red) and actual (blue) RF levels measured from a similar smart meter in southern California (chart courtesy EMF&RF Solutions, www.EMFRF.com).

I checked in with an associate who has a PhD in electrical engineering: how many high peaks could you have, and end up with a low average? We invented an example and calculated the average level using information from the FCC’s own document addressing the matter. A thirty-minute period could contain one hundred (100)  5-millisecond pulses  (at 900MHz) (duty cycle=0.02%), each pulse a whopping 100,000 µW/cm² each (the big unit), and the averaged level could be calculated to be around 28 µW/cm². The device’s maker could then claim this constituted only about “5% of FCC limits.”But a person standing in that field would actually be subjected to very high bursts of RF energy, which have been shown to have biological effects.

This engineer then set out to find what the maximum allowable peak pulse is, according to FCC standards, and particular,what power density would a smart meter pulse be permitted to peak at? Although there is a reference to a “guideline” of 4,000µW/cm² as determined by ANSI/IEEE C95.1-1992 in the Sage Report discussion on peak power limits, we couldn’t find explicit limits stated anywhere else. Here is a recognized dangerous substance, and there is effectually NO regulation on the upper limit of peak pulses the public is exposed to.

Are you an electrical engineer who can tell us what that upper limit on the peak pulse of a PG&E smart meter is?What is allowable? Calculated? Measured? We want to know. Write info@StopSmartMeters.org, and if you can back up your claim, Stop Smart Meters! will consider a guest post where you can tell readers what you know.
The time-averaging issue shows up an important point: patterns of exposure—like these sharp spikes—are not part of the FCC’s considerations concerning the effects of RF on humans. This is a serious oversight, and any revision of the FCC guidelines should address this as well. 

The best analogy to these spikes of RF energy is a strobe light. Using the same energy as a low-watt bulb, a strobe light produces very intense millisecond pulses of light, several per second, and has been shown to adversely affect the brain, inducing seizures in some people. RF is an electromagnetic energy like light, but one that penetrates into the surface of our bodies. (This paper by Karl Maret, MD, has excellent references on pulsed RF effects on humans.) 

Many observers trying to reckon with the sheer number and consistency of smart-meter health complaints have seriously wondered whether this particular under-regulated and unaccounted-for factor might be at the heart of the harm done by wireless utility meters.
