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