The BBU3900 supports a maximum of 24 cells and supports diverse configurations from 1 x
1 to 6 x 4 or 3 x 8.
N x M = sector x carrier. For example, 3 x 1 indicates that each of the three sectors has one carrier.
1.3 RRUThe RRU is the outdoor remote radio unit. The RRU is the RF module of the distributedNodeB and is installed close to the antenna.
1.3.1 Specifications of the RRU
The RRU is classified into the RRU3804, RRU3801E based on different output power andprocessing capabilities.
The RRU3804 and RRU3801E have the same appearance and they only differ in specifications.
Table 1-1 describes the specifications of the RRU.

2Products and Application Scenarios
2.1 Application Scenarios
2.1.1 Distributed NodeBDBS3900
As there are increasing concerns about environmental protection and lease cost, site selectionhas become a bottleneck in network deployment. It is increasingly difficult to adopt 2G/3Gco-siting or to select a new site.
The distributed NodeB (DBS3900) developed by Huawei features high integration, easyinstallation, and low power consumption. All these features facilitate site reselection and
2G/3G co-siting. In addition, the RRU can be installed close to the antenna. In this way, thefeeder consumption is reduced and system coverage is improved.
The DBS3900 provides flexible applications for different scenarios and facilitates fastnetwork construction.
Outdoor Integrated Application
If only the AC power is available at a new outdoor 3G site and power backup device is
required, the combination of DBS3900 and APM can function as an outdoor macro NodeB.Figure 2-1 shows the typical configuration of DBS3900+APM.
This configuration has the following features:
l The BBU3900 and transmission equipment are installed in the APM cabinet and theRRU is installed close to the antenna.
l The APM provides installation space and outdoor protection for the BBU3900 and
supplies 48 V DC power to the BBU3900 and the RRU. In addition, the APM performsmanagement and monitoring for batteries, and provides surge protection for the entirecabinet.

Embedded Application with Existing Site Equipment
For the 2G/3G co-siting scenario, the BBU3900 is installed in a standard 19-inch-wide and 2
U-high cabinet, and the RRU is installed close to the antenna, as shown in Figure 2-2. TheBBU3900 and the RRU share the power backup system, transmission system, and antenna
system of the BTS in the 2G network. In this way, operators can launch 3G services on theexisting 2G network at a very low cost.
