Clifton Elementary School

 

At Clifton Elementary School, fourteen (14) exterior survey locations measured and recorded the total PCS RF emission, PCS cell phone receive band (1850 to 1910 MHz), the PCS cell phone base station transmit band (1930 to 1990 MHz), the local radio FM transmit bands (88 MHz to 107.9 MHz) and the local television transmit bands (174.0 MHz to 806.0 MHz), consisting of local television Channels 7 through 70. This selected FM/TV measurement does not take into consideration local television Channels 4 and 5, which have a transmit frequency lower than the SRM-3000 can read.

 

Analysis of the data sets, shows that they are distributed log normal rather than normally distributed. The geometric mean is less affected by extreme values than is the arithmetic mean (average) and is useful as a measure of central tendency for log normal distributions.  That being said, the geometric mean would be more appropriate than the arithmetic mean in analyzing the data.

 

Outside the Building PCS Frequency Field Survey

 

The following graph represents the outside the building measurements at Clifton Elementary School as they compare to the FCC exposure standard for the PCS frequency band of 1 milliwatt per centimeter squared (mW/cm2) or 1,000 microwatts per centimeter squared (uW/cm2).
