Local Drug Store had 4 Cell towers put up on the roof..
One story building, School Bus Stop directly in front

Druggist, she is quite upset..

Anyone know how much power these ( average Cell tower) puts out ??

Would you have one in your Living room.. ten feet away ?? twenty feet
??



It depends on the density of cells in the area. If there are other cells
closely adjacent, then they may run as little as 4 watts. If there are no
closely adjacent cells, they can run upward of 400W EIRP. Antenna structures
are designed to put most of the power in the horizontal plane, with nearly
zero power going in a vertical plane (directly below the tower). 400 watts
would be hazardous if you were 2 feet from the radiating elements, but I2R
losses are significant, and the power level at 60 feet from the tower is
measured in mW rather than watts. (the necessary received signal for a phone
to operate is in the low nanowatts, and remember, this same tower has to be
able to receive a signal FROM the phone, which has less than 300mW of output
power)
