What does turning up the transmit power or utilizing a high-gain antenna increases your exposure to?

Answer 1

Turning up the transmitter power is a good way to insure that more cellphones, farther away, can hear the base station. But it doesn't to anything to help the base station hear the cellphones that are farther away. The only way to increase the coverage range reciprocally is to do something with the antenna. But that's a catch-22 . . . a higher-gain antenna has a narrower beam-width. So it works farther out, but only through a narrower 'window' of directions.

Answer 2

Using a high gain antenna, or turning up the transmit power, will increase exposure to UHF radio frequencies. It can also increase exposure to electromagnetic radiation in relation to the UHF frequencies.

Answer 3

It increases your exposure to electromagnetic radiation with UHF radio frequencies.

If you were standing 1 mile away from a wireless base station, which transmitted 50

watts of power from an antenna with a gain of 10,000 (40 dB), and you carefully

positioned yourself precisely in line with the antenna's direct beam, your unshielded

body might then absorb as much as 0.0154 watt of RF ... not much more, perhaps,

then you're exposed to when you hang around in the kitchen waiting for the corn to

pop in the microwave.

======================================

A moment ago, I took my cellphone out of my pocket, and brought up the screen

that shows me the strength of the 'wireless' signal the phone is receiving now, in

my home-office. It's -87 dBm.

That's 0.000000000002 watt.
