2 DBS3900 Hardware Configuration
About This Chapter
This describes the Typical Configurations of the DBS3900, 4-Way RX Diversity Configuration,
TX Diversity Configuration and 2 × 2 MIMO Configuration.
2.1 Typical Configurations of the DBS3900
The capacity of the DBS3900 can be expanded through addition of modules or license upgrade.
When license upgrade is required, the capacity can be expanded by 16 cells at a time. In the
early phase of network construction, you can choose a small-capacity configuration (such as 3
x 1 configuration). When the number of subscribers increases, you can smoothly expand the
small-capacity configuration to a large-capacity configuration (such as 3 x 2 or 3 x 4
configuration).
2.2 4-Way RX Diversity Configuration
The DBS3900 supports 4-way RX diversity configuration.
2.3 TX Diversity Configuration
The DBS3900 supports TX diversity configuration.
2.4 2 x 2 MIMO Configuration
The DBS3900 supports 2 x 2 MIMO configuration.
