In order to meet the actual needs of large-scale network construction and energy conservation and environmental protection, major equipment manufacturers have introduced new ideas from different perspectives on the base station as a "large power consumer", or a new "packaged" equipment layout, or started from each link to add innovative technologies. After undergoing various forms of "plastic surgery", traditional base stations are appearing in a brand-new look. In the process of accepting the test of the current network environment, transcripts on energy-saving and environmental protection answer sheets are successively given.

"ZTE Tree" Tower: a new generation of green energy base stations
ZTE has launched a series of new energy-saving integrated base station solutions-"ZTE Tree", which integrates a variety of innovative elements to create a harmonious and unified communication base station. Compared with traditional communication base station solutions, the most prominent features of ZTE Tree are: intensive, energy saving, environmental protection, and beautiful.
* Intensive: Through the clever design of the equipment layout, the site land area is reduced to the greatest extent, and the difficulty and cost of land acquisition are reduced.
* Energy saving: The adoption of zone temperature control technology greatly reduces the power consumption of the site. At the same time, the unique design shortens the distance between the antenna system and the RF unit, reduces the energy attenuation caused by the feeder, and reduces the power consumption of the device under the same network capacity and coverage.
* Environmental protection: The site power adopts complementary solar and wind energy solutions to make full use of green energy.
* Beautiful: simple appearance, light design, smooth lines, harmonious and unified with the surrounding environment of the scenic area.
Actual combat
Shanghai Bell: CBO outdoor station withstood the test of the Qinghai-Tibet Railway
Choosing the right product according to the actual use environment can avoid excessive occupation of resources and energy. The full range of base station products can undoubtedly meet the needs of different scenarios. Shanghai Bell is fully prepared for this. Its base station receiver sensitivity is up to -116dBm, using 60w high power carrier frequency, supporting four-way receive diversity and transmit diversity, which can increase the coverage of 20% to 40%, helping operators use the minimum number of base stations to obtain maximum network coverage. Shanghai Bell's GSM outdoor base station has a truly integrated structure, which is stable and reliable, adapts to various environmental requirements, does not require the construction of supporting facilities such as computer rooms, power racks, and air conditioners. It can save more than 60% of supporting investment and save more than 80% of post-operation Maintenance costs, and take advantage of the convenience of base station installation to shorten the project construction cycle. The outdoor station also supports built-in microwave, satellite, optical fiber and other transmission equipment. Shanghai Bell also provides energy solutions such as light energy, wind energy and biogas power generation. Each base station saves about 6,000 yuan per year and reduces carbon dioxide emissions by 5.1 tons. Based on the current network of 10,000 base stations, a total of 50,000 tons of carbon emissions will be reduced every year.
In addition, Shanghai Bell's GSM base stations all support smooth evolution capabilities and can support GSM, WCDMA, and LTE in a single cabinet. With the introduction of the MCPA module, supporting module-level sharing of GSM, WCDMA and LTE not only protects operators' early network investment, but also meets the development needs of network technology. It is an important part of energy conservation and emission reduction.

Huawei: Multi-angle introduction of key technologies to reduce consumption
Huawei uses two levels of network topology and network elements to design energy-saving sites. At the network topology level, site energy saving is mainly to improve coverage efficiency and improve the coverage capability of the base station equipment itself. Huawei uses PBT, TransmitTIngDiversity, AMR, HighReceiveSensiTIvity and other key technologies, combined with the joint use of the two methods, to achieve more than 25% energy consumption savings in a wide coverage scenario, resulting in a considerable decrease in TCO.
Compared with network topology energy saving, energy saving at the network element level mainly focuses on base station energy saving, cooling system energy saving, and new energy system. Huawei uses multiple technologies such as multi-carrier, intelligent voltage regulation, intelligent shutdown, and new high-efficiency power amplifiers to reduce waste and redundancy. Among them, Huawei is the first in the industry to provide a slot-level shutdown function, so that the energy consumption of the base station can be more accurately matched. Changes in business load reduce waste.
In terms of reducing feeder losses, Huawei's innovatively designed distributed architecture base stations and small base stations help operators successfully solve this problem. Under the condition that the set-top power is unchanged, in the actual network deployment, the distributed base station can replace the traditional macro station to achieve more than 40% power saving. In addition to this, the distributed architecture can also bring savings in renting computer rooms and supporting cooling systems. Under normal network conditions, both high-efficiency base station products and distributed architectures can achieve a network TCO reduction of approximately 10%.
In addition, the introduction of non-emission energy and low-emission energy (such as solar energy, wind energy, bio-energy, etc.) new energy based on local climate factors is also the most effective way for enterprises to reduce carbon emissions and save energy consumption. Huawei has targeted Innovative EasyGSM solutions are proposed to support low-cost and rapid deployment and have a good return on investment.

Noci: Flexi Shelter Outdoor Base Station Cabinet
With the rapid development of the mobile communication industry, in order to achieve seamless coverage of mobile networks, major operators have set off a new wave of network construction and optimization. Affected by factors such as tight site resources in urban areas, blind signal areas, and insufficient coverage in rural areas, the traditional model of building a computer room is difficult to meet the requirements of operators' network construction, and the proportion of outdoor base stations is increasing.
The outdoor cabinet refers to a cabinet made of metal or non-metallic materials directly under the influence of the natural climate, which does not allow unauthorized operators to enter the operation, and provides an outdoor physical working environment and safety system equipment for the communication site. Suitable for outdoor environment, such as roadside, park, roof, mountain, flat installation cabinet, the cabinet can be installed base station equipment, power supply equipment, battery, temperature control equipment, transmission equipment and other supporting equipment or reserved for the above equipment installation Space and heat exchange capacity can provide reliable machinery and environmental protection cabinets for the normal operation of internal equipment.
The characteristics of Noci outdoor cabinet include:
Adapt to harsh environments. The design of the cabinet follows the relevant international standards. All cabinets have adopted an effective protection design and the protection performance reaches IP55 to ensure the safe operation of the equipment. The use of 45mm thick low thermal conductivity sandwich material board, combined with a variety of flexible temperature control solutions, minimize system energy consumption and reduce operation and maintenance costs.
Flexible deployment. According to actual needs, it can support 19-inch (IEC297), 21-inch (ETSI) standard racks, and support the installation of various other equipment that meets the size of the cabinet installation space requirements.
Anti-theft performance. With good rigidity and strength, the whole cabinet is installed without glue, the design of the right door is opened, the three-point locking structure of the world, the external padlock, and the built-in hinge.
