Product Description
Huawei DCOM 1800 for Huawei BTS3012
HUAWEI BTS3012 BTS312
The Huawei BTS3012 is a type of indoor macro base station. It features high integration and excellent performance, thus meeting the requirements for the long-distance coverage of the GSM-R network along railways.When applied in the GSM-R network, the BTS3012 uses the double-transceiver units (DTRU). A BTS3012 cabinet supports a maximum of 12 TRXs.
High Reliability
Huawei BTS3012 is capable of operating with two reliability-enhancing features that are of particular interest for GSM-R networks:
The BTS3012 supports the "single frequency double coverage" feature
The single frequency double coverage scheme enables two BTSs working in active/standby mode to cover the same area. In addition, only one of the BTSs is working at any specific time. The two BTSs use exactly the same frequencies. In normal cases, the active BTS works properly, whereas the standby BTS works but does not transmit power. When the active BTS is faulty, the BSC triggers the switchover between the active BTS and the standby BTS. Specifically, the previously active BTS is downgraded to "standby BTS" status, whereas the previously standby BTS is upgraded to "active BTS" status. This redundant coverage does not require any additional frequencies compared to single coverage, thus improving network availability and ensuring continued network operation even in the case of a BTS failure.
The BTS3012 supports the "single frequency TRX redundancy" featureThe single frequency TRX redundancy feature enables a BTS to be configured with a standby TRX that shares the same frequencies with an active TRX. When the active TRX is faulty, the standby TRX is automatically activated to take over, thus improving network availability and ensuring continued network operation even in the case of a BTS failure.
Coverage Capability
The BTS3012 has the following benefits in terms of coverage:
High receive sensitivity
The static sensitivity of the TCH/FS channel is –112.5 dBm (a typical value in normal temperature)
Power boost technology (PBT)
The maximum transmit power of the DTRU can reach 100 W.
Transmit diversity and 4-way receive diversity
Networking Capability
The BTS3012 has the following benefits in terms of networking capability:
Supports multiple transmission modes such as E1, T1, and STM-1 transmission.
Supports multiple topologies such as star, tree, chain, ring, and hybrid topologies.
Supports automatic fast switching to the backup route in ring topologies, without any interruption of ongoing services.
Antenna
The BTS3012 has the following benefits in terms of antenna:
Supports Remote Electric Tilt (RET) antennas.
Supports dual polarization antennas. This reduces the number of antennas in a cell.
Installation
The installation of the BTS3012 has the following features:
The BTS3012 supports installation against the wall.
The external cables come into the BTS through the top of the cabinet.
All the cables are accessible from the front of the cabinet.
The field installation personnel only need to position the cabinet, insert the boards, install the external cables, and download the data configuration files.
The simple and fast installation of the BTS3012 software and hardware helps to minimize the delay to install and deploy a network.
Working Frequency Bands
Table 4-1 lists the working frequency bands of the BTS3012. The space between carriers is 200 kHz.
BTS3012 working frequency bands
Frequency Bands | TX | RX |
E-GSM 900 | 925 MHz to 960 MHz | 880 MHz to 915 MHz |
R-GSM 900 | 921MHz to 960MHz | 876MHz to 915MHz |
GSM 1800 | 1805 MHz to 1880 MHz | 1710 MHz to 1785 MHz |
Transmit Specifications
Table 4-2 lists the nominal output power of the DTRU.
