I would expect the FCC having some literature on this.  Maybe some
sort of comparison to mobile phones?

Well, that depends on the carrier.  There's a lot of 1800 - 1900 MHz cell 
use out there vs. 800\900 MHz.

I would ask them what a permissible level would be, then I would give them 
some average levels of exposure due to cell phone and microwave oven leakage 
(and wireless routers, maybe) showing them to be thousands of times higher 
than the wisp gear.  You could always put up an AP and use a spectrum 
analyzer to show how much weaker your signal is compared to the residents 
cell phone.

If they cannot cite a level, then an analysis cannot be done.  You can cite 
FCC docs on legal levels of exposure.

Also emphasize that cell phone frequencies are centered around maximum 
biological heating frequencies.  Wisp gear is much higher (unless you are 
using 900 of course).

Re: [WISPA] RF Radiation Analysis

2008-10-23 Thread 3-dB Networks 
In the back of the Canopy user manual it shows what the FCC Guidelines
are... for Canopy gear it has to be installed 5 inches I think away from an
area people would normally be in...

Find the FCC regs, then do the math to show them what the permissible limits
are.  I think they will be surprised

Re: [WISPA] RF Radiation Analysis

2008-10-23 Thread Brian Webster 
To get someone to come out and do that won't be cheap. You might want to try
and find some examples of the power levels of each type of device like
microwave ovens, cordless phones, cell towers and such and show how they
compare to your power levels and the maximum permissible exposure
guidelines. That may be enough when you list your specs and those charts to
keep you from having to pay someone to do the on site work. I remember doing
zoning hearings for different cell towers over the years and our people had
made presentation boards with those comparisons. I don't have any of those
charts but you might find something on Google. "Maximum permissible exposure
guidelines" should be a good search term.
