HUAWEI DBS3900 Telecom Equipment
Original HUAWEI DBS3900 GSM Base Station Telecom Equipment IEEE 802.16e CE
Description:
The DBS3900 WiMAX is the distributed WiMAX BS developed by Huawei and complies with IEEE 802.16e standards. Currently, the DBS3900 WiMAX satisfies the application requirements of high-end mobile WiMAX networks, and thus is applicable to global markets. Its coverage and capacity are expanded through 4T4R multi-antenna technologies, its maintainability and testability are improved, and thus it provides subscribers with the wireless broadband access services of large capacity and high quality.

Applications:
With advanced technologies, the DBS3900 WiMAX implements wide coverage and has high network performance.
It supports multi-antenna technologies, with which multiple types of gain (such as power gain, space diversity gain, space multiplexing gain, array gain, and interference suppression gain) can be obtained so that coverage is expanded and system capacity is improved.
− On the downlink, the following multi-antenna technologies are adopted: MIMO A, MIMO B, CDD, and BF (that is supported only when the BS uses the 4T4R technology).
The BF technology is a method of weighting target subscriber channels to form narrow beams directed to the subscribers. With this technology, array gain and diversity gain can be obtained to expand coverage. In addition, a narrow beam is formed for each subscriber so that the energy of each narrow beam is intensive. Therefore, the interference on the subscribers in neighbor cells is reduced.
− On the uplink, the following multi-antenna technologies are adopted: CSM, MRC, IRC, and MIMO (that requires the two-antenna transmission mode supported by the MS). The MIMO technology improves throughput and coverage on the uplink.
It supports HARQ, which integrates FEC and ARQ to improve transmission quality and expand coverage.
It supports open loop and closed loop power control to minimize fading effects and interference, thus improving transmission quality.
It supports AMC, and thus the system specifies appropriate modulation and coding modes according to channel quality.
− When channel quality is good, the high-order modulation scheme and high-rate coding mode are used to achieve higher transmission rate.
− When channel quality is poor, low-order modulation scheme and low-rate coding mode are used to ensure transmission link quality.
It supports the 64QAM technology.
A high-order MCS is used on the uplink, and thus each subscriber occupies a relatively few time frequency resources. In this way, the system can serve more subscribers, and throughput and capacity are improved on the uplink.
