At least 5 test points for each type are attempted. This may be difficult, depending upon the
actual deployment scenario. Results may yield a very large percentage in one of the categories.
For selecting an even spread across a 120 degree sector for a panel antenna installation, divide
the 120 degrees into 6 even slices of 20 degrees each. Then divide each slice into 2 Km
segments. This spaces each location at an approximate even distance throughout the complete
sector and yields 36 test sites.
To select an even spread across a 360 degree cell for an omni antenna installation, divide the 360
degree cell into 12 even slices of 30 degrees each. Next, divide each slice into segments based on
distance (1 Km or 2 Km, depending upon propagation). This will approximately space each
location an even distance from each other throughout the complete cell, yielding approximately
48 test sites (based on a 4 Km cell radius). To do this, split the cell into 4 quadrants. Using the
RF coverage analysis, select up to 16 locations per quadrant (Figure H1). Pay particular attention
to null areas and the cell edges. At these locations you will perform a file transfer to measure the
data rates available. The FTP/Location Test Tool program and the BTS Beamforming Display
tool will be used to record RF parameters during each test. Figures H1 and H2 provide examples
of simple guidelines for selecting an even spread across a cell area.
