JULES COHEN 6 ASSOCIATES, P.C. CONSULTING ENGINEERS 42 ► WASNINGTON. D.C. 20036 Engineering Statement Page 6 Cantoro, North Carolina strengths, it was not possrble to distinguish cellular signals from ambient electromagnetic noisy Inside the equipment rack that housed the cellular transmrttem exposure Ievels were found also to be below the sensitivity threshold of the electromagnetic monitor. Thexre were 22 cellular Viers installed at the site at the time of the survey. Taking into accoi transmitter power output. trams mission line loss, and antenna gain, the effective radiated power of each transmitter is nominally 100 warns. Assuming sirmikaneoas operation of all transmitters, rnr6mnm effective radiated paw= at the site is 2200 watts Gives the height above ground level of the transmitting antenna and the directivity of the oraatmistmg antennas m the vertical pbM the estimated exposure level six feet above grand level at the tower, base is less than 0.0003 mW/erns, which is equivalent to 0.01 percent of the WE for controlled environments and O.OS percent of the NeE for uncontrolled environments. Conchssioa RFR exposure levels measured on the grcumd and inside die equipment shelter at the INKA293 site were more than are hundred times less than the protection guides set forth in ANSI C95.1-1982 and the applicable IPEs set forth in 095.1-1992. It is e»ely hYely that a more sensitive eiecmoamagaetic monitor would show the exposure levels to be thousands of tinxs less than the mss estiWWwd by the standards. Further; public access to the site is restricted, ftx, by a fear enclosing the self-storage complete within which the cello lsr site located, a4-second by a fence enclosing the tower base, Absent any chaftes to the man system, routine masta'emeat of elecnromagruutic field streiigths at the KIVKA293 site would save no purpose other than to prove well established Im of physics by --munatiaq that no change in the transmission system
