Challenges
It is a global consensus that energy efficiency and emission reduction are critical to sustainable development.
Rapid global economic development has led to severe energy shortage and environmental pollution. International organizations and governments have enacted policies aimed at improving energy efficiency and reducing carbon emissions. Meanwhile, the global ICT industry has begun to research energy efficiency standards. The world's big-name operators and equipment vendors have mapped out a series of energy efficiency and environmental protection standards.
Our Solution
It is Huawei's conviction that energy efficiency is an important part of operators' commitment to environment protection and cost reduction and that energy efficiency design for networks needs to be integrated with the assessment of TCO as financial feasibility is an important indicator of a good energy saving solution. Huawei conducts a lifecycle assessment (LCA) on its own equipment from the carbon emission perspective during the equipment's lifecycle, with focus on mobile BTSs and fixed broadband access products. Our main conclusion from our LCA is that a typical BTS discharges the most carbons during its operation stage, which takes up 60% of all the emission during the whole lifecycle. Based on its energy consumption analysis for a number of its customers, Huawei has found that electricity is the major energy consumed, mainly on access networks. For mobile operators, wireless sites account for 70% of the energy consumption; even in the case of fixed operators, energy consumed by the access part goes as high as 40% of the total consumption or more. Therefore, Huawei believes that energy savings on access networks come first, then on core equipment rooms, and lastly on transmission networks and that packaging and logistics can be carried out in a green way. Always innovative in its energy efficiency approaches, Huawei has developed such end-to-end solutions as Green Site, Green Equipment Room, Green Transmission, and Green Energy.
Green Energy
- The coming five years will see new subscribers come from emerging markets, where power supplies for BTSs are often compromised by the lack of grid power or unstable power, poor infrastructure, difficulty in getting fuel for diesel generators and maintaining BTSs regularly in remote areas. This often results in high costs. To help operator overcome these challenges, Huawei has come up with the Solar Energy Solution, Wind and Solar Hybrid Power Solution, and Solar and Diesel Power Solution.
Green Site
- Huawei has substantially helped reduce BTS energy consumption and carbon emissions through a series of innovative techniques such as improving power amplification, adopting smart power control, increasing the maximum temperature for the BTS, and employing distributed or integrated equipment rooms.
Core Equipment Room
- Huawei has replaced blade servers for traditional servers so as to drastically reduce energy consumption in the core equipment room. Employing All-IP, MSC Pool and ngHLR, Huawei helps operators save on energy by streamlining the network and reducing the amount of equipment. The cooling efficiency in the existing equipment room can be improved by using intelligent applications and equipment thermal management techniques.
Green Transmission
- Smart networking is the best way to reduce energy consumption as far as green transmission is concerned. As for the network, Huawei's ASON is a good solution for optimizing the network and cutting the number of sites and equipment rooms, while in terms of equipment, the back-to-back router configuration and large-capacity OTN/OCS are innovative techniques for equipment energy savings.
Green Packaging
- Practicing 6R1D, Huawei uses recyclable timber and visualized packaging techniques and promotes assembly packaging, standardization, and appropriate design. It has developed various green packaging techniques, which, in combination with its recycling logistics platform, form a suite of green packaging solutions..
Applications & Benefits
Huawei's green communications solutions have helped operators achieve significant energy savings. With its SingleRAN@Broad solution, it will help operators better respond to the explosive growth of broadband business by reducing the per-bit cost and improving QoE, and therefore promote the MBB industry. Furthermore, its new energy solutions allow its customers to make configurations depending on their requirements and local climates to support multiple application scenarios and achieve TCO reduction and energy savings. According to its 2010 shipment statistics, more than 6,100 cubic meters of timber were saved due to green packaging, and CO2 emissions cut by 12,000 tons accordingly.
