This Is Questionable I Believe

Not only power level but wrong frequency. The resonant freq. of water is 2.5GHZ (what your microwave oven produces). Cell phones are running either 800, 900 or 1.8, 1.9 GHZ.

Low frequency is more harmful to tissue than high freqs (<1MHZ).

I would think the 30yrs of cell phone use with no increase in brain cancer rates would be enough for these idiots, but then again they are idiots so...

There is 1 more band that you did not mention that is just over the last 2 years begun to be used. You are correct on the bands listed, but AWS band operates on 1.7Ghz for TX and 2.1Ghz for RX

Just curious, are you in the mobile phone industry? Not many people in the US know the European frequencies.

I've got close to 30yrs in electronics...

ET in the Navy, Motorola for about 9yrs (2-way, paging, telemetry), another 8 as paging system engineer, last 11 owner of three Nextel / Sprint stores plus wireless telemetry service co. (mainly public utilities)

Not glowing yet, you would think I'd be well done by now.

Those AM transmitter sites, now those will cook you with enough exposure, not to mention getting lit up by unbonded metal within a hundered feet or so of the radiators.

Wow, not too different. ET in the Navy on Submarines for 6 1/2 years, Qualcomm for 2 1/2, and Samsung for almost 9 1/2 so far as a Mobile phone Service Engineer and Customer support Engineer. You got a few more years on me, so hopefully I do as well.

Got tired of hopping jobs after the paging industry sunk, so the self employment was a survival move. You know your heading for that age where no one will hire you. At least now I can move my company into whatever new technology comes along and not have to clean my desk.

Of course now I have to kiss everyone's azz, instead of just "the boss".

But, I've got some great people working for me and hope that they eventually become business owners themselves. 30yr jobs in technology fields are practically non-existant anymore, the company you work for simply won't exist in a few years.

Not to mention I will never, ever, ever work for a large corporation again.

Ron - Yep, had my share of RF burns over the years. Keyed a radio into the center of my palm one time, skin turned white, and a chunk about the size of a small pea fell out two days later. Had a hole in my palm for about a month.

Ronbo,

They sure do take time for that small hole to fill back in. But it taught me a lesson that I really remembered when working on the microwave up link system later on. The labs did some tests on all different frequencies of microwaves, even tried a very low frequency to see if it would travel through water so they could contact subs with it. Only caused a lot of headaches and other problems.

The Rf Frequencies from the old style overseas radio stations were dangerous too. I once heard of a guy who didn't shut the transmitter down going into the tube room and having his arm severed. My worst thing was just a tiny prick from one of the military radios as I used a lead pencil to test if I had them tuned to max power and this one happened to be a good one and went right through the lead and left a spot the size of the lead in my finger. It almost 10 years for that spot to finally come out. And it stung like mad but it sure made me pay attention when I was working on the high power microwave and other systems.
