2 DBS3900 Hardware ConfigurationAbout 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 4configuration).

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.

small-capacity configuration to a large-capacity configuration (such as 3 x 2 or 3 x 4

configuration).

Table 2-1 and Table 2-2 show the typical configurations of the DBS3900, where the WBBP

supporting three cells is taken as an example.

NOTE

l N x M = sector x carrier. For example, 3 x 1 indicates that each of the three sectors has one carrier.

l Assume that the number of RRUs is a when the RRUs are configured in no TX diversity mode. Then,

under the same configuration, the number of RRUs is 2a when the TX diversity mode is applied.

2.2 4-Way RX Diversity Configuration

The DBS3900 supports 4-way RX diversity configuration.

In 4-way RX diversity configuration, the DBS3900 consists of the WMPT, WBBP, and

RRU3804s. The WMPT and WBBP are installed in the BBU3900. The WBBP supports

configurations of three cells and six cells. The following description is based on the WBBPsupporting six cells.
