My recollection is that the old analog cell phones were allowed 3 watts; hand-helds were limited to 600 milliwatts. I was just researching the actual limits, reading OET Bulletin 65 on RF exposure. It appears to me that the legal limit for "uncontrolled" exposure above 1500 MHz (e.g., Clearwire) is 1 mW/cm^2. From 300-1500, it's f/1500, so at 700 MHz (VZ LTE), it's about half that. Turning that into exposure uses this formula: EIRP/(4*pi*(d^2)) So 6 watts EIRP at 1 meter gives a density of .05 mW/cm^2. So that's about a tenth of the limit. But at about 30 cm, around a foot, you cross over the line, if I'm doing the calculations correctly. > On 02/23/2014 06:15 PM, Josh Luthman wrote: >> Anyone know the eirp for 700 MHz 4g? >> >> Josh Luthman >> Office: 937-552-2340 >> Direct: 937-552-2343 >> 1100 Wayne St >> Suite 1337 >> Troy, OH 45373 >> >> On Feb 23, 2014 9:12 PM, "Robert" <nos...@avantwireless.com >> <mailto:nos...@avantwireless.com>> wrote: >> >> I just recommended HomeFusion service to a prospective customer. >> Buried deep in the pine trees, they had one slot that a competitor was >> able to deliver service through.
