2.2.3 Rack Configuration
Samsung’s BTS supports both omni and three sector configurations. Each deployment location has unique
characteristics that drive specific configuration requirements. Samsung’s BTS is designed with maximum
configuration flexibility. The following are some configuration examples:
A three-sector cell uses one basic rack for one CDMA carrier and can accommodate a maximum of
seven CDMA carriers with five racks.
An omni cell uses one basic rack for three CDMA carriers and can accommodate a maximum of
seven CDMA carriers with two racks.
Table 2.4 summarizes the Samsung BTS configuration examples discussed above.
Figures 2.3 and 2.4 show the maximum rack configuration for Samsung omni and three sector
BTSs.
