Reduced service delay



Higher user data rates



Increased spectral efficiency



Optimized support for packet services



Improved system capacity and coverage

LTE has flexible bandwidths, enhanced modulation schemes, and effective scheduling. In addition, LTE allows operators to use both original and new spectral resources to provide data and voice services.

1.1 Positioning Focusing on customer-oriented innovation, Huawei launches a series of LTE products in its SingleBTS product portfolios, including BTS3900 LTE (indoor), BTS3900A LTE (outdoor), and BTS3900L LTE (indoor). These base stations fully utilize Huawei platform resources and use a variety of technologies to meet the challenges of mobile network development. The E-UTRAN NodeB (eNodeB) is used for radio access in the LTE system. The eNodeB mainly performs Radio Resource Management (RRM) functions such as air interface management, access control, mobility control, and User Equipment (UE) resource allocation. Multiple eNodeBs constitute an E-UTRAN system. Figure 1-1 shows the eNodeB position in the network.

As SingleRAN solutions, the BTS3900 LTE, BTS3900A LTE, and BTS3900L LTE enable smooth network evolution and reduce the cost of LTE site deployment by sharing Huawei SingleBTS hardware platform and equipment with other base stations: −

BTS3900/BTS3900A/BTS3900L GSM

−

BTS3900/BTS3900A/BTS3900L WCDMA

−

BTS3900/BTS3900A/BTS3900L CDMA



The BTS3900/BTS3900A/BTS3900L LTE can share the network with GSM or UMTS base stations and support handovers between LTE and the PS domain of the GERAN/UTRAN/CDMA2000. This facilitates LTE network deployment in the existing GSM or UMTS network.



The BTS3900/BTS3900A/BTS3900L LTE supports RAN sharing. Different operators can share the RAN network, reducing capital expenditure (CAPEX).



The BTS3900/BTS3900A/BTS3900L LTE enables GSM, UMTS, and LTE modules to share one indoor macro cabinet or outdoor radio frequency (RF) cabinet, which saves installation space and facilitates resource utilization.



The BBU3900 is the baseband unit (BBU) of the BTS3900/BTS3900A/BTS3900L LTE. The BBU3900 supports multi-mode applications. Therefore, boards of different modes can be installed in one BBU3900.

Large Capacity, Extensive Coverage, and High Throughput 

The BTS3900/BTS3900A/BTS3900L LTE provides large capacity. A single eNodeB supports a maximum of 3600 UEs in RRC_CONNECTED mode.



Enhanced SON Function 

Automatic configuration The BTS3900/BTS3900A/BTS3900L LTE can automatically obtain connection parameters, download software, configure data, conduct tests, and upload information. This facilitates preparation for data configuration, reduces manual handling during site deployment, and minimizes operational expenditure (OPEX).



Automatic Neighbor Relation (ANR) The BTS3900/BTS3900A/BTS3900L LTE can automatically maintain the integrity and validity of the neighboring cell list by automatically detecting missing neighboring cells and evaluating neighboring cell relationships. This increases handover success rates and reduces the cost of network planning and optimization.



Automatic detection of Physical Cell Identifier (PCI) conflicts, sleeping cells, and antenna faults PCI conflicts, sleeping cells, and antenna faults are automatically detected and reported, reducing the workload of manual identification of network faults.

Comprehensive IP Transport 

Various transmission ports are provided, such as FE/GE electrical ports, FE/GE optical ports, and E1/T1 ports.



Internet Protocol (IP) transport is supported. In addition, diversified network topologies are supported, such as star, chain, and tree topologies.



Multiple Quality of Service (QoS) mechanisms are applied to provide high capacity, implement differentiated services, and meet the QoS requirements of services.

Easy Maintenance and Low OPEX The BTS3900/BTS3900A/BTS3900L LTE has only two types of basic modules. The basic modules and auxiliary devices can be combined in many ways to meet different requirements. This centralized installation mode reduces maintenance on the tower and helps cut OPEX for operators.
