What is the maximum value of power density at most of mobile phone dish antennas located in phone base station?

What is the maximum value of power density at most of mobile phone dish antennas located in phone base station?|||Hi there





Forget Gurus answers , its garbage.


The link he provided was not for cell phone towers.


They were for transmitters in the hi VHF to low UHF range.





Cell phone base stations operate at less than 100 watts , often less than 10 watts.


Their high unobstructed location is their key to their good range., not power output.





Some towers are even in the 1 watts level , which is only 4 to 8 times more powerful than a normal cell phone.





The FACT IS , is that you get higher exposure to RF fields from the phone stuck to the side of your head than from the base stations.|||your hand held phone is 2 to 5 Watts but very close to you

base stations are 1 to 10W in super market stores arena, shopping malls...

over 1000W in some rural areas



a microwave oven, about the same frequency 2400 MHz, is about 800W of output

What is the root of your question?

The signal from cell phones is very complex and so is the power measurement

The link I sent from Amplifier research was just to show what such an amplifier may look like. They differ vastly from one another.



This link http://www.nxp.com/documents/leaflet/750… Is that of a transistor manufacturer.

This particular model is 47dbm module

If you email me I will most likely answer all your questions

But generally everything is limited to 5Watts
