China Mobile Beijing & ZTE’s PON Smart Energy-Saving Plan

ZTE Corporation is entering into a collaboration with China Mobile Beijing to trial the PON smart energy-saving solution in its existing network. This is a proactive step for both ZTE and China Mobile Beijing in strengthening the green broadband network.

China Mobile Beijing and ZTE have worked together previously in 5G expansion, network infrastructure and technology development. 

The PON Smart Energy-Saving solution

ZTE is a provider of communication technology solutions, founded in 1985. It builds integrated solutions for global operators across 160 countries, with a vision to ‘enable connectivity and trust everywhere’.

The global telecom industry has a role to play in reducing carbon emissions, by finding new sustainable manufacturing processes and ways to save energy. Otherwise, the telecom sector’s operations will continue to contribute significantly to global carbon emissions. ZTE recognises the urgency of sustainable transformation and is setting ambitious targets to reduce its environmental impact. 

Meanwhile China Mobile, which has the biggest number of mobile subscribers in China and offers mobile voice and multimedia services through its vast mobile telecommunications network, is promoting a climate strategy with energy saving and emission reduction as its core. China Mobile is also working together with its value chain stakeholders and customers to minimise its impact on the environment.

Together, China Mobile Beijing and ZTE have proposed the "PON Smart Energy-Saving" solution.

This solution uses intelligent analysis technologies to build a smart energy-saving architecture, allowing the EMS (Element Management System) to analyse and control network resource configurations and energy-saving models. 

This allows for local decision-making and automatic execution of NEs (Network Elements), through considering factors affecting the energy consumption of OLTs (Optical Line Terminal), using the power consumption of OLTs and allowing low-carbon reconstruction through digital usage. The solution facilitates the achievement of the dual-carbon goal.

This initiative will use new technology to link EMS and NEs. It intelligently controls the dynamic sleep and startup of OLTs, through changes in resource configurations in the existing network and the operational status of the OLTs, to make energy savings and emission reductions.

Based on the results of the pilot and the scale of OLTs deployed in the existing network, China Mobile Beijing anticipates substantial savings: 

• A reduction of 427,000 kWh in electricity consumption
• A reduction in carbon emissions by approximately 132 tonnes. 

This initiative will be a solid foundation for China Mobile Beijing to strengthen green, low-carbon and sustainable development.

Despite sustainability drives, e-waste is a growing problem for the mobile sector

In addition to its emissions, the mobile sector must also address the environmental impact of e-waste. E-waste refers to anything with plugs, cords or electronic components which has been discarded. Since these products usually contain hazardous materials, they can release toxic chemicals into the atmosphere when they aren’t disposed of correctly. The Waste Electronic and Electrical Equipment (WEEE) forum reported an estimated 57.4m tonnes of e-waste globally in 2021, which is heavier than the weight of the Great Wall of China. 

China Mobile is working to improve its e-waste management by enlisting the public to participate in environmental protection and promote a low-carbon economy. Meanwhile, ZTE is reducing the volume of hazardous substances used in its manufacturing and increasing the use of recyclable materials.
