1 Introduction
1.1 Positioning
The rapid development of mobile communication technology brings sharp growth in the
number of mobile phone users. This growth creates increasingly high requirements for
network quality. Besides enhancing network coverage, operators also need to increase
network capacity to meet rapid increases in traffic volume.
In many hot spots, insufficient of network capacity and the existence of blind spots greatly
affect user experience. To solve these problems, operators urgently need an accurate and
low-cost coverage solution with flexible site deployment.
Following the philosophy of continuous innovation based on customers’ requirements,
Huawei unveils the industry-leading WCDMA mini base station BTS3902E. Characterized by
its small size, light weight, plug-and-play functionality, auto-configuration, and no
requirements for shelter or equipment room, the BTS3902E is flexible in site acquisition and
deployment, making it a quick and flexible site solution for operators.
The BTS3902E is a bi-carrier product. Figure 1-1 shows the unit.

1.2 Benefits
Compact Structure for Quick Network Construction
With a highly integrated design, the BTS3902 is small, light, and requires less spare parts,
making it easy to install and maintain. The BTS3902E features strong environment
adaptability and has no need for an equipment room. It can be flexibly mounted on a wall or a
pole. The BTS3902E supports both integrated and separated antennas.
Expanded Capacity and Enhanced Coverage
The BTS3902E accurately absorbs traffic, and therefore expands network capacity and
reduces blind spots. This helps operators enhance network quality and user experience.
Low Power Consumption and Energy Saving
The BTS3902E is another green base station launched by Huawei. It assists operators in
constructing eco-friendly networks.
Smooth Evolution and CAPEX Saving
The BTS3902E supports HSPA+, and can provide high-speed data services in urban hot spots.
