indoor t-mobile access point, how safe is it?

Posted: 02-13-2004, 12:23 AM
Hi

T-mobile (USA) installed a number of squint ceiling mount
omnidirectional antennas in the building where I work.
Model is: Cushcraft SQ1853P 1850-1990mhz, 3.5dbi.
I have no idea how much power t-mobile is putting out
on them and I am becoming concerned about long term
health implications because one of them is mounted 5
feet away from my head.
Does anyone know what power levels t-mobile might be
puting out on these indoor antennas and how dangerous
they are?

thanks in advance,
Slava.

IN the envirornment you describe, power is probably limited to 100mw,
although you should be able to ask T-mobile about it. Also the gain
on the antenna says they are not omni directional, so if it is 5 feet
away, I assume it is about 5 feet above you. The pattern from the
antenna probably puts out almost no energy either straight up or
straight down. It doesn't do any good.

There are no proven hazards to exposure at that sort of level, and
while many claims have been made, none of the claimed results has been
reliably reproduced under controlled conditions.

By the same token military and police have been exposed to higher
levels for much longer periods of time, and we don't seem the dropping
like flys from various forms of cancer.

In short there may be a hazard, but it cannot be much of a hazard
because it hasn't been quantitified yet, i.e. it is within the noise,
so does not materially the risk above normal background.

These type antennas put out 10 watts:

They are rated for 10 watts, that doesn't mean they are fed with 10
watts! There is a big difference. Your wall outlet may be rated for
15 amps, that doesn't mean anything you plug into is rated 15 amps
does it?

I stand by the 100 mw figure. It meet BRH requirements, whereas a 10
watt antenna inside an occupied space would violate BRH regulations.

Correctitude. My apologies.
