    Woah isn't exposure to anything less than -10 dbs in the cancer causing range? ;)

    Hey if I go climbing I'm sure I can challenge that. LOL There's one gas station in San Fernando that has a Sprint antenna on a sign and I was getting -28 dbs while on the ground pumping gas. If I brought an extension ladder with me I'm sure I could get it down to -17. :D

    i basically touched the phone to the front of the panel, just long enuff to see how low i could get it. A couple of mins wont hurt you. It takes about 30 mins, recommended max for those not familiar with RF to notice the effects.

    I have to carry a rad meter in my truck, it will go off in a cell site building.

    It shouldn't... though maybe break 50% exposure? Maybe with near the filter/duplexer to antenna connections but the system should be pretty leak free inside the base station itself.

    Unlike some of the people here who work with cellular antennas, I usually don't even know where the nearest antenna is. ;) I just think it is interesting to look at the range of RSSI numbers I get when my LG CU500 reads 5 bars. Currently in my hotel room in Ft. Lauderdale (I'm working... really!) the main display has 5 bars and the RSSI has been as strong as -78. Not impressive for you tower-climbing types, I know.

    I wish I knew what all of the other readings meant (test mode has 15 screens in 3 groups). When I get a chance I will take a few pics of them and maybe the kind folks here will enlighten me.

    Later that day on Atlantic Avenue in Pompano, FL, I got an RSSI of -62.

    My rad meter is a joke. I was playing with it and put it in front of a hot panel antenna and it didnt go off but have had it go off in a building. I was right next to the duplexer shelf.

    My best reading was -37 dB off an ATT panel.

    Hahah, gotta love those Narda (assuming...). Though I can't complain about my new RadManXT. It actually works pretty well.

    Because of the way the LG CU500 shows the field test display, you can actually see the edges of the regular display at the same time. Today I watched it hovering around the 4 bar/ 5 bar boundary and saw that -84 or stronger is 5 bars. -85 is 4 bars.

    LG is obviously saying that's what's needed for optimal performance - anything more is overkill - and they use the signal meter display in the range between -84 and -100 or so. I'm not sure if this is the same on other phones, but I suspect it is similar.

    It could be using S/N Ratio, Ec/Io, etc to determine the bar reading.

    Nextels seem to display bars based solely on SQE readings. I'll have to keep an eye on mine to see if I can get 4 bars around -90 again in a quiet area.

    It could be, but it sure seemed directly related to RSSI. Every time it went across the -84/-85 boundary, the bars changed and vice versa. If there were another factor, wouldn't they move independently some of the time? I really don't know much about this, I'm just reporting what I saw.

    Every test phone I have had has full bars at -84 db or better.
