$ro"le)atic Areas – Co&era'e
•  In road &$@@, etween sites !10/8 and !10A8B, the 3G coverage is ad ecause this sites present a physical con>guration to assure coverage in neary villages. The most predominant cell detected y scanner was !10:/32, which is located around $C m of distance. In the kalkreuther street there is no 0)T& coverage at all, due to the terrain environment.
• The only solution is add a new site that could assure coverage in all this area.

$ro"le)atic Areas – Co&era'e
• In the map is highlighted the part of Dresdner street, &$@B, where the 3G coverage is ad. This happens ecause the environment of this area is diEcult to cover. The three '& drops achieve during the DT occurred in this area.
• The only solution is add a new site that could assure coverage in this part of road.
 
For internal use
$ro"le)atic Areas – Co&era'e
• The existent sites donFt allow the continuity of the 3G service in &$@@, near the location of 6oden. 2lso here the only solution is a new site.

• The image aove show the signal level achieved for sector !10:BB' +&' $/H%. Is important reduce the electrical and mechanical tilt in order to reduce the spreading of main loe in the dominance area of other cells. This way, we can also reduce the pilot pollution in the marked areas.
