Motorola multi-carrier amplifier base Station Glow GSM new Vigor

With the development of GSM network and the continuous increase of the number of users, the traditional GSM base station technology can not meet the requirements of network quality promotion and new business development.　　Motorola went to the forefront of the industry, launched a support for 20MHz bandwidth, the industry's most integrated GSM Multicarrier amplifier (MCPA) base station, the base station is Motorola in the field of GSM continuous innovation in the latest results.　　Motorola GSMMCPA base station can greatly reduce energy consumption, single module can support 8 logical carrier, easy to smooth expansion, and support RF pull far, flexible deployment, with software upgrades, support to E-edge and LTE smooth evolution of the ability.　　1. A significant reduction in energy consumption base station is the entire wireless network of the most power-consuming equipment, and the base station power amplifier unit power consumption of more than 70% of the base station, so improve the power amplifier technology, improve the efficiency of the power amplifier is to reduce the base station power consumption is an important means. With Multi-carrier amplifier, Motorola MCPA base station also applied digital predistortion and Doherty advanced amplifier technology.　　Motorola MCPA Base Station power amplifier efficiency can reach more than 30%, is the existing traditional GSM base station twice times. Taking the base station of S666 configuration as an example, in the typical power consumption index, the base station using MCPA technology is 910W less than the base station using traditional PA technology, and the power consumption is reduced by 54%.　　In addition, compared with the traditional base station, the MCPA station of the whole station efficiency increased by a full times.　　Suppose the base station equipment load is 60%, take one 1000 S666 base station network for example (18,000 carrier network), use MCPA Base station, one year can save electricity: electricity saves =365 (day) x24 (hour) x60%x910wx1000=478.3 million kwh. 2. High integration, smooth expansion Motorola GSMMCPA base station with high integration characteristics, single carrier module supports 8 logical GSM carrier frequency, while the traditional GSM carrier module supports 2 logical carrier frequencies maximum. From the equipment integration, the new MCPA carrier plate is the traditional GSM carrier plate 4 times times. This means that through the Motorola GSMMCPA base station, operators can significantly increase capacity under the same configuration, and reduce the number of base stations, resulting in a significant reduction in operational costs and difficulty. In addition, the Motorola GSMMCPA base station supports smooth expansion and can be installed for different capacity requirements.　　Therefore, compared with the traditional GSM carrier plate, the cost of MCPA base station is obviously reduced. 3. Flexible deployment, save room In addition, Motorola GSMMCPA base station also supports RF pull far deployment mode.　　The so-called RF pulled is to pull the RF module of the base station to the far end near the antenna.　　Because of the support of RF technology, MCPA Base station only baseband processing module and other auxiliary units, compared with the traditional GSM, the same configuration, MCPA Base station can use a much smaller cabinet. For example, for a S666 Configuration of Acer Cellular base station, the use of traditional GSM base station needs to configure 2 macro-cellular cabinets, the total volume of 0.45m3. The S666 configuration of the MCPA base station only uses a real volume for 0.087m3 micro-cellular cabinets.　　Compared with the traditional GSM base station room space occupancy, the use of Motorola MCPA base station, occupancy room space for the traditional GSM base station occupies 1/5 of the space. At the same time, due to the use of RF technology, Motorola MCPA base station is also conducive to the rapid and easy deployment of base station operators.　　RF Pull Far unit can be placed in the tower or hold the top of the pole, thereby reducing the use of the day feeder, but also reduce the transmission power on the feeder loss. 4. Future-oriented Evolution Motorola MCPA base station adopts RF part and baseband process part separation design, RF part only transceiver, amplifier and other RF devices, so only through software upgrades can support the future of mobile communications technology.　　In other words, the deployment of Motorola's MCPA base station is also ready for future operators to upgrade to E-EDEG and LTE, which will protect the operator's investments to the fullest extent possible. As early as the second half of 2009, Motorola as the first manufacturer successfully completed the China Mobile Research Institute's GSMMCPABTS Laboratory Test and the Chinese mobile network test, obtained the China Mobile network card and industry and information Technology Department of the network card and model approval certificate.　　At present, Motorola's GSMMCPA base station has begun to apply to China Mobile network. Looking forward to 2010, the development of GSM base station based on MCPA technology will become the technical hotspot in the industry. Adhering to the concept of mutual win with the operators, Motorola from the customer interest and market demand, launched an innovative GSMMCPA base station, for operators to upgrade the existing GSM network sustainable competitiveness and sustainable profitability provides an effective tool.
