3900 Series Base Station Product Description

1

Introduction

1.1 Overview To keep abreast of rapidly advancing mobile communications technologies, mobile operators are continually seeking partners who provide cutting-edge technologies to set up high-quality, multimode-enabled, and future-oriented mobile networks efficiently and cost-effectively. With this aim in mind, Huawei developed 3900 series base stations, which are designed based on a high-performance platform and use an optimized hardware and software architecture. These base stations can work in multiple modes due to their cutting-edge modular design. They also have broad bandwidth and are eco-friendly and easily upgradeable. Specifically, 3900 series base stations use the newly developed power amplifiers (PAs), provide the temperature control function, and employ the innovated power saving technique. In addition, by adopting the cutting-edge modular design, 3900 series base stations use multimode modules with different appearances to meet requirements in various conditions. Thanks to all these merits of 3900 series base stations, mobile operators can set up high-quality, multimode-enabled, and future-oriented mobile networks and capital expenditure (CAPEX) on site acquisition, capacity expansion, and environment protection can be greatly reduced. Different types of 3900 series base stations can be delivered on request because the newly designed modules and auxiliary devices can be flexibly combined and configured. Figure 1-1 shows the different types of 3900 series base stations.

1 Introduction

1.2 NodeB Expansion 3 Sector to 4 Sector Huawei NodeB product can support expansion by sector and carriers. If Expansion from 3 sector to 4 sector, only need to add one R F module and the software license. It s very easy to deploy and maintenance. ’

1.2.2 BBU3900 As a baseband control unit, a B BU3900 provides the following functions: 

Centrally manages the entire base station, including operation and maintenance, signaling processing, and the system clock.



Processes uplink and downlink baseband signals.



Provides physical ports, which are used to connect the base station to the transport network for information exchange; a maintenance channel, which is used to connect the BBU3900 to the operation and maintenance center (OMC); CPRI ports for communication with RF modules; and ports for communication with environment monitoring devices. shows the slot layout of a BBU3900.

NOTE

For more details about the BBU3900, see the BBU3900 Description.

1.2.3 RRU As an RF component on a distributed base station, the RRU modulates and demodulates baseband and RF signals, combines and divides baseband and RF signals, and processes data. RRUs can be installed on a pole, wall, or stand. They can also be installed close to antennas to shorten the feeder length, reduce feeder loss, and improve system coverage. RRUs fall into the following three types: 

1 Introduction

The RRU3229, RRU3841, RRU3829, RRU3929, RRU3942, and RRU3961 are recommended for use in APM30H (Ver.C)/APM30H (Ver.D) or TMC11H (Ver.C)/TMC11H (Ver.D) cabinets. When the RRU3229, RRU3841, RRU3829, RRU3929, RRU3942, or RRU3961 is used in an APM30H (Ver.B) or TMC11H (Ver.B) cabinet, some auxiliary devices must be reconstructed. Other types of RRUs can be used in any cabinet type. NOTE
