Nokia rolls out liquid cooling and AI for 5G in Japan

Nokia is conducting a trial using its AI-based Liquid Cooling AirScale Baseband solution with Japanese mobile operator, KDDI. 

The trial will demonstrate how KDDI can reduce its baseband cooling system energy consumption by more than 70 percent compared to traditional gas coolant based air-cooling solutions. 

Traditional air-cooling systems are noisy and require regular maintenance such as filter changes and re-gassing. Nokia’s Liquid Cooling system is almost maintenance free and virtually silent. Along with machine learning algorithms, this reduces cooling-system-related CO2 emissions by more than 70 percent.

The AVA AI algorithm, developed at Nokia Bell labs in the US, blends telecoms expertise, AI and cloud-based delivery into a coherent energy control that dynamically adapts energy consumption to traffic levels.

“This trial is another milestone in Nokia’s commitment to sustainability and combatting climate change. Nokia was the first vendor to introduce this game changing liquid cooling solution which supports operators in their quest to be more environmentally responsible while allowing them to achieve significant cost savings,” said John Lancaster-Lennox, Head of Market Unit Japan at Nokia.

This follows the commercial rollout of the technology with network operator Elisa in Finland. This was is the first time a commercial 5G liquid cooling solution has been deployed anywhere in the world.

“We want to maintain our 5G leadership and continue to be amongst the top operators in the world to offer the wide benefits of this new technology to our customers. Innovations such as Nokia’s liquid cooling 5G base station demonstrate how 5G can help drive sustainability,” said Sami Komulainen, Executive Vice President of Production at Elisa.  

“Nokia was first to introduce a liquid-cooled base station with the 2G, 3G and 4G base stations with Elisa in Finland. Now we have demonstrated the world’s first liquid-cooled AirScale 5G base station in commercial operations, making liquid cooling a reality for all network generations,” said Tommi Uitto, President of Mobile Networks at Nokia.
