the base of the monopole and the power density is 0.001761 mW/cm2 with an <br /> assumed power level of 2,000 watts. This is 0.3303% of the MPE limit for the <br /> general population/uncontrolled exposure of 0.533 mW/cm2 as referenced in <br /> Table I OET Bulletin 65 Appendix A for the lowest frequency range. <br /> OTHER CARRIERS <br /> The following are examples of wireless carriers providing service in Snohomish <br /> County: <br /> ESMR 851-866 Mhz Nextel <br /> Cellular 869-894 Mhz AT&T, Verizon <br /> PCS > 1800 Mhz Sprint, T-Mobile, AT&T <br /> In order to develop a "worst case prediction", it is assumed that all other wireless <br /> facilities on the tower have maximum effective radiated power (ERP) levels of <br /> and 2,000 watts for the wireless carrier panel antennas. <br /> Wireless facility antennas are highly directional and project the majority of the RF <br /> energy horizontally. Attached as an exhibit are the MPE (Maximum Permissible <br /> Exposure) calculations using the referenced power density formula. These <br /> calculations assume that the vertical patterns of the antennas suppress the ERP <br /> by 20 dB towards the antenna base. The calculations show that the maximum <br /> total MPE at ground level (6' above AGL) at the base of the monopole is <br /> 0.002751 mW/cm2. This is 0.5891% of the MPE limit for the general <br /> population/uncontrolled exposure of 0.467 mW/cm2 for the lowest frequency <br /> (700/1500) as referenced in Table I OET Bulletin 65 Appendix A. <br /> COLOCATED FACILITIES TOTAL MPE <br /> The combined MPE for the Sprint antennas and the existing carriers using "worst <br /> case" calculations is: 0.001761 mW/cm2 + 0.002751 mW/cm2 = 0.004512 <br /> mW/cm2 Total MPE. <br /> ENVIRONMENTAL EVALUATION <br /> Routine environmental evaluation is required if the PCS broadband facility is less <br /> than 10 m (32.81 feet) AGL and has a total power of all channels in any given <br /> I/3 `t <br />
