In-depth exploration of broadband access network energy saving solutions

The broadband access network in China is developing very rapidly. So I have studied the detailed solutions for the broadband access network, and I will share them with you here, hoping to help you. The design of the network emission reduction scheme should be combined with the evaluation of Total Cost of Ownership. The Cost reduction scheme with high economic feasibility is the preferred solution.

From the perspective of carbon emissions in the life cycle of communication products, has made a life cycle evaluation (LCA) for self-produced devices, focusing on base station products in mobile networks and broadband access network products in fixed networks. Our main conclusions of the LCA evaluation are: for a typical BTS device, the biggest stage of carbon emissions lies in the operation stage (USE 1 ), in this phase, carbon emissions account for about 60% of the overall life cycle. In other words, operators are under greater pressure on energy conservation than equipment suppliers.

From the perspective of energy consumption, analyzed the energy consumption based on the current network data of multiple customers and found that the main form of energy consumed by operators is electric energy, the main power consumption is in the broadband access network, including wireless sites and wide/narrow band broadband access networks. The energy consumption of wireless sites of multiple mobile operators is more than 70%, the power consumption of fixed carriers in the broadband access network is slightly lower than that of mobile networks, but it is also more than 40%. To sum up, the focus of Network Energy Saving lies in the broadband access network site, followed by the core data center, and finally the transmission network. In addition, for the same packaging and transportation problems in the manufacturing industry, the new logistics technology can achieve the goal of saving energy and reducing consumption.

Green Base Station

In site construction, the "enhanced gain" technology is used to "Reduce the number of sites". In equipment construction, using broadband access network technologies such as "distributed architecture", "optimized power amplifier efficiency", and "optimized power distribution" to save energy, the new integrated data center reduces the energy consumption required for cooling, reduces emissions.

Green integrated data center

During the construction of the core data center, the "all ip" architecture, "MSC Pool" and "ngHLR" architecture were used to simplify the network, reducing the footprint of the equipment and data center, this greatly reduces energy consumption. In terms of equipment in the IDC room, the traditional Minicomputer is replaced by the dc atae server, and smart software is used to save energy during idle network periods. In addition, the hot management of the IDC room is used to greatly improve the cooling efficiency of the existing IDC room.

Green Transmission

The use of ASON networking increases transmission efficiency by 75%, and the transfer "Bypass" function achieves a maximum exchange capacity savings of 30%. The use of devices has successively increased the integration level, improving the energy efficiency by 30% compared with traditional devices.

Green Supply Chain

We put forward the 6R concept in the innovation of the Green Supply Chain packaging and logistics module, and adhere to the implementation of RoHS (limits on hazardous substances for motor and electronic equipment), WEEE (Instructions on Waste motor Electronic Equipment) and EuP (Instructions for energy-consuming product environmental protection design) to implement SA8000 Social Responsibility certification standards, so as to effectively achieve energy-saving purposes.
