BTS Sector Configurations
There are a number of ways to configure the BTS frame. Table 1-5
outlines the basic requirements. For more detailed information also see
Table 1-6, Figure 1-6 and Figure 1-7. Bandpass filters are used for
single–carrier configurations and two–carrier systems when carriers are
either adjacent or not adjacent
Table 1-5: BTS Sector Configuration
Number of
Carriers
Number
of Sectors
Channel Spacing Filter Requirements
1 3 N/A Bandpass Filter or 2:1 Combiner
2 3 Adjacent or Non–adjacent Bandpass Filter
2 3 Non–adjacent 2:1 Combiner
The matrix in Table 1-6 shows the correlation between the various sector
configurations and BBX cards.
