JULES COHEN & ASSOCIATES, P.C. CONsULTINO ENGwms 42 WASHINGTON. D.C. 20036 Engineering Statement Page 6 C,anboro.,North Carolina =cwths, it was not possible to distingtuah cellular signals from ambient electromagnetic noise. Inside the equipment rack that housed the cellular tiaasmitte:s, exposure levels were found also to be below the sensitivity threshold of the elecoromagaetic monitor. There were 22 cellular transmittecs installed at the site at the time of the survey. Taking into account transmitter power output, ttaasmission line loss, and antenna gam, the effective radiated power of each transmitter is nominally 100 watts. Assuming simuhaaeots operation of all naamnitters, muimum effective radiated power at the site a 2200 watts Given the height above ground level of the trazI mittiag antennas and the directivity of the antennas in the vertical place, the estimated wgxm= level sit feet above ground level at the tower base is less than 0.0003 mw/cm`, which is egi&aleat to 0.01 perc m of the WE for controlled environments and 0.05 percent of the WE for uncontrolled environments. conc RFR cq me levels measured on the ground and inside the equipment shaker at the KNKA293 site were more than one hundred times less than the protect= guides set foal m ANSI C95.1-1982 and the applicable MM set forth in C95.1-1992. It is ca remelt' lilmly that a more sensitive elecorounagaetic mooko`would show the cqx mm levels to be thousands of times lest than the maxirutunus estabfid ed by the simudards. Further, public access to the site is restricted, firm, by a tmm aociosiog the self-storage complex within which the celldar site located, " secood, by a fmcx enclosing the tower base. Abe= any changes to the tiammission system, routine measurement of elec tromagruetic field stranobs at the KNKA293 site would serve no purpose other than to prove well established laws of physics by demoastiating that no change in the transmission system
