Nokia, Elisa and Efore have commercially deployed has announced a proof of concept (PoC) deployment of a liquid cooled base station system in an apartment building in Helsinki, Finland. The Nokia designed PoC liquid cooled base station was done in collaboration with network operator Elisa and power systems supplier Efore.
Nokia Bell Labs developed the base station, while Efore developed the liquid-cooled power system and Elisa handled deployment.
Analysis from Finland’s VTT Technical Research Centre indicates that the deployment reduced CO2 emissions by up to 80% and energy operating expenses by up to 30%.
Minna Kröger, Director, Corporate responsibility from Elisa, said: “We have set science-based targets to reduce our emissions in our effort to become an environmental leader, and we are committed to providing customers the services that enable them to act in a sustainable way. We are excited to leverage the extensive expertise of Nokia and Nokia Bell Labs for this important deployment.”
“Nokia and Nokia Bell Labs have conducted extensive research and testing to explore the possibilities of using a liquid-cooled base station in an operator’s network,” said Pekka Sunström, head of the Elisa customer team at Nokia.
“This first commercial deployment will enable us to understand the real-world benefits for customers such as Elisa as they transition toward 5G, and how the system can be implemented on a wider scale to help reduce the environmental impact of information and communications technology,” he added.
Vlad Grigore, Chief Technology Officer of Efore, said: “We are dedicated to providing efficient and reliable power supply solutions tailored to our customer’s needs. The power system pilot with MHE (Modular High Efficiency) rectifiers adapted for liquid cooling helps reduce energy consumption and emissions, with a positive impact on environment. We are enthusiastic about this development that continues our long tradition of close cooperation with Nokia.”
