L EIN NEEIRING 8� EMC TEST LABS INC. CONSUiTINQ COMMUNICATIONS ENGINEER'S•EVCTEST LABORATORIES $144 Ham, goo Atiaima IIort6,Sharevlew,NN 551218 061-784 T485•Fax 661.784-7541 Engineering Statement In reviewing the submitted data for the proposed communications facility on the Bethel University campus by AT&T it was determined that additional information for nearby AT&T telecommunications sites was needed in order to make a signal coverage study determination. The requested information was provided and the data was analyzed. This analysis shows how AT&T has designed its communications facilities in the Arden Hills area with several surrounding sites providing area wide coverage. In discussions with AT&T engineers it was noted that the design of their system differed from ordinary system designs in that the college campus has many buildings that presently have very poor in-building coverage. The proposed site is intended to give good coverage within the campus area. An area of concern expressed by the city was to determine if an existing water tower could be used to provide the required coverage area for the AT&T communications system. In reviewing the location of the water tower and the communications facilities locations, the water tower to the west is too far from the proposed new AT&T site and - cannot provide the required coverage area to eliminate the signal coverage gap. Figure 1 shows the location of the proposed site and the water tower (WT). On August 18, 2010 measurements were taken on the Bethel Campus to verify the existing coverage area and also to determine the in-building signal attenuation to use in the coverage study computer model Figure 2 shows the results of the coverage study analysis using the data for this proposed site in addition to the data supplied by AT&T for the nearby system sites. The analysis was then repeated with the proposed site removed from the analysis in order to determine if there is any gap in coverage in the AT&T system in the proposed coverage area. Figure 3 shows that a gap in coverage does exist and is identified. The analysis was repeated using the water tower (WT) as the location of the communications system. Figure 4 shows there would be a significant gap in coverage for the communications system.
