1 Introduction

1.1 Product Positioning

The mobile communications industry has been surging forward by establishing a dynamic

growth with the upgrade of technologies and products. The growing trend of mobile

communications comprises a series of evolution, from GSM to Enhanced Data rates for GSM

Evolution (EDGE) to EDGE+ and from WCDMA to High Speed Packet Access (HSPA) to

HSPA+ and Long Term Evolution (LTE), and it is worth mentioning that WiMAX also joins

the 3G family. To follow the trend, the network operators have to devote more CAPEX and

OPEX to the dramatic change of technologies, and therefore they are currently focusing on

merging multiple network systems into a more cost-effective one.

After the transition of mobile networks, the network operators target at the Blue Ocean

Strategy and invite innovative and responsive partners. Customer-oriented and innovative,

Huawei advocates four basic technological concepts: green, merge, wideband, and evolution.

Huawei will take the lead in developing the next-generation base stations and the 3900 series

NodeBs, which are Huawei's fourth generation base stations. This will outclass other base

stations to benefit operators with future-oriented networks.

Huawei unveils cutting-edge techniques in the 3900 series NodeBs, such as wideband,

multi-mode system, and modular design. The 3900 series NodeBs consist of only three basic

functional modules, characterized by compact structure, high integration, low power

consumption, and easy and quick deployment. Flexible combinations of functional modules

and auxiliary devices enable Huawei to diversify the products. More importantly, the modules

of different modes (GSM/UMTS/LTE) can be installed in one cabinet to work as a base

station adapting to different scenarios. Huawei also introduces new frequency bands and

technologies to well meet operators' requirement for a compact multi-mode mobile network

system.

Figure 1-1 shows the basic functional modules and auxiliary devices of the 3900 series

NodeBs.

1.2 Product Features

Adaptable to Diversified Radio Environments

Different combinations of functional modules and auxiliary devices diversify the NodeB

products. For example, there are macro NodeB, distributed NodeB, and mini compact NodeB,

which operate in different scenarios to better meet different network deployment

requirements.

The 3900 series NodeBs provide a platform for the Huawei wireless products. Specifically,

the base stations of different network systems such as GSM, WCDMA, CDMA, and WiMAX

can share the same cabinet or even share one functional module at the same frequency band

(based on the Software Definable Radio (SDR) technology), which makes it easy for network

operators to choose a site type.

Greatly Reduced Total Cost of Ownership (TCO)

The 3900 series NodeBs have many advantages, such as flexible installation, easy site

selection, cost-effective solution, and fast network construction. The baseband module

(BBU3900) is only 19 inches wide and 2 U high, taking a very small indoor space or taking a

place in an outdoor cabinet. The RF module (RRU3900) can be installed close to the antenna

without taking any space of the equipment room.
