above 4 sites. For clarity, the predicted coverage from the Tower was not included. This allows depiction of the void in the coverage without the Tower. The coverage of each sector is shown by different colors. This a"best server" plot where areas shown for ~ each sector depict the strongest signal. Thus, any overlap of sector coverage would not be shown. ~ Results ~ The design of wireless telephone systems, e.g., cellular and PCS, involves controlling the propagation (coverage) of each cell such that a small area (cell) can be covered ~ efficiently and, at the same time, minimize interference to other cells utilizing the same frequency groups. Controlling the signal levels at the perimeters of each cell is also very ~ important because of the requirement that when a subscriber passes from one cell to another, the call is uninterrupted because of low signal levels. This is called, "hand-off'. ~ Because of this, the layout of the cells becomes very location-critical. ~ The analysis was conducted considering only the coverage of each sector and did not include capacity, interterence or hand-off analyses. ~ In order to maintain the inte9ritY of the desi9n of the s stem, it a Y ppears that the Tower ~ should be located within the area shown on the plot (Exhibit TCG-1). This area is approximately 1 mi X.6 mi. There was no effort by TCG to determine whether or not ~ there was availability of a tower or property for a tower in this area. 19 Conclusion It is the opinion of TCG that because of the critical aspect of the design of the LU ~ system, the Tower should be located somewhere within the area depicted on the coverage plot of Exhibit TCG-1. ~n ~.1~. 4 •e•-;~ y • r , ~ Raymond C.
