Even with power saving technologies, they can consume lots of power even when network traffic is extremely low. During deep sleep, the active components of the active antenna unit (AAU) \/ remote radio unit (RRU) continue to consume dozens of watts of power. Further reducing power consumption and scaling these power saving solutions to all sites are key to addressing energy use and emissions from mobile networks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To explore the potential for further optimisation of base station energy consumption, ZTE has investigated hibernation technology. Hibernation refers to a state of reduced power consumption where all the modules of the AAU\/RRU, except for a tiny power supply module, are muted. By activating hibernation, the energy consumption of the AAU\/RRU in idle mode can be lowered to 3W, even lower than common household LED lamps.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"581\" src=\"https:\/\/www.gsma.com\/solutions-and-impact\/connectivity-for-good\/external-affairs\/wp-content\/uploads\/2024\/02\/ZTE-1024x581.png\" alt=\"\" class=\"wp-image-10471\" srcset=\"https:\/\/www.gsma.com\/solutions-and-impact\/connectivity-for-good\/external-affairs\/wp-content\/uploads\/2024\/02\/ZTE-1024x581.png 1024w, https:\/\/www.gsma.com\/solutions-and-impact\/connectivity-for-good\/external-affairs\/wp-content\/uploads\/2024\/02\/ZTE-300x170.png 300w, https:\/\/www.gsma.com\/solutions-and-impact\/connectivity-for-good\/external-affairs\/wp-content\/uploads\/2024\/02\/ZTE-768x436.png 768w, https:\/\/www.gsma.com\/solutions-and-impact\/connectivity-for-good\/external-affairs\/wp-content\/uploads\/2024\/02\/ZTE.png 1130w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Hibernation can be implemented across all ZTE&#8217;s AAUs\/RRUs delivered in the past four years through a software upgrade, without requiring additional hardware. Integration with the operator&#8217;s maintenance platform can be achieved quickly by implementing a consistent operation interface with carrier shutdown and deep sleep, without the need for relearning. Consequently, hibernation can be deployed throughout the entire network in a short period.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, hibernation represents an optimal integration of hardware design and software algorithms, effectively matching real-time load and adapting to different shutdown levels. This approach prevents issues such as equipment condensation and broken solder joints, which are common with air-switch-based shutdown solutions and can result in shortened equipment lifespan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hibernation has been successfully implemented in over 350,000 5G AAUs in China, leading to an average annual energy saving of 75 million kWh compared to deep sleep mode. In August 2023, hibernation was further developed to include RRUs because of ongoing technological advancements. Thorough testing and verification have demonstrated the standby power consumption of the RRU can be as low as 3W during idle periods. This significant reduction in power consumption contributes to energy efficiency. Moreover, the RRU can quickly respond to the network&#8217;s user demands, activating within approximately one minute when needed. This rapid response time enhances the user experience and elevates the overall service quality.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Radio devices are the biggest source of energy use and carbon emissions of a mobile network.
