In rapidly changing field of mobile communication, there is utmost need for continuous

improvement in the products. The growing trend in mobile communications comprises of aseries of evolution: from GSM to EDGE to EDGE+, and from UMTS to HSPA to HSPA+,

and LTE. To keep pace with the trend, the network operators are forced to increase theCAPEX and optimize the OPEX with the changing technologies, and therefore operators are

currently facing the challenge of merging the multiple network subsystems into a more cost-effective network. The solution is to move towards the convergence of multi-mode networks.

As an innovative and customer-oriented company, Huaw

fourth generation BTSs, which will outclass other base stations to benefit operators withfuture-oriented mobile networks. The BTS3900 GSM and the BTS3900A GSM (hereinafter

referred to as BTS3900 and BTS3900A respectively), are indoor macro BTS and outdoormacro BTS of the fourth-generation BTSs respectively.

1.2 Benefits

Simple Structure and Multi-Mode Convergence

The BTS3900 and BTS3900A have only two types of basic modules. The simplified structurereduces spare parts and saves maintenance cost. The basic modules combined with different

cabinets increases the variety of installation modes, such as separate mode and stack mode.The BTS3900 and BTS3900A can support multiple network modes by sharing one cabinet or

using the same transmission and network management system, thus achieving theconvergence of multi-mode networks.

Broadband Service and Enhanced User Experience

Considerable improvement has been made on the BTS in terms of baseband processing and

internal bandwidth expansion, and support MCS-9 services at all timeslot levels on the air

interface. IP transport is supported on the Abis interface, the transmission bandwidth expands

enormously, which further enhances the user experience.

Low Power Consumption

Thanks to the advanced hardware designs, for example, multi-carrier PA, as well as a series of

software power saving technique, the power consumption of the BTS3900 and BTS3900A is

greatly reduced, which helps in deploying an environment friendly network.

Smooth Evolution and Reduced CAPEX

The BTS3900 and BTS3900A supports smooth evolution to EDGE+. During the evolution, all

the hardware can be reused. The BTS3900 and BTS3900A can also support multiple network

modes by adding RF modules, which helps operators to reduce CAPEX.

3.2 Portfolio and Application of Fourth-Generation BTSsBy providing various product forms of fourth-generation BTSs to cater the demand fornetwork deployments in different scenarios, Huawei provides operators with a comprehensive

total network solution. Huawei fourth-generation BTSs consist of the indoor macro BTS(BTS3900), outdoor macro BTS (BTS3900A), distributed BTS (DBS3900), and compact

BTS (BTS3900E).

The BTS3900 applies to indoor installation scenarios where population density is high, trafficis large, lease expense for equipment rooms is high, and space is limited. The BTS3900A

applies to outdoor installation scenarios in urban, suburb, and rural areas where large-capacityand wide coverage is required. The DBS3900 applies to outdoor scenarios where wide

coverage is required and site construction is difficult. The BTS3900E applies to indoorcoverage and coverage in hotspot areas. Figure 3-6 shows the applications of the Huawei

fourth-generation BTSs.
