Nokia and Elisa see sustainability leap in world-first 5G liquid cooling deployment.

As operators around the world race to roll out new 5G networks, maintaining sustainability goals is very much on their minds.

Indeed, the ongoing COVID-19 pandemic has placed the climate crisis into sharp focus, and governments and companies are being called on to perpetuate the unplanned environmental benefits brought by lockdowns.

In terms of 5G, Nokia said its liquid cooling basestation technology helped Finish mobile operator Elisa reduce potential site energy costs and CO2 emissions at its Helsinki site by 30% and 80% respectively.

Nokia claims to be the only telecom equipment vendor to offer the technology across 2G, 3G, 4G and 5G networks, and is now delivering liquid cooling with the Nokia 5G AirScale basestation.

According to Nokia, “this is the first time a commercial 5G liquid cooling solution has been deployed anywhere in the world.

” Liquid cooled sites are said to be silent, require zero maintenance, and can be 50% smaller and 30% lighter than standard active air conditioning units. “They offer operators and owners of basestation sites significant savings and potentially longer base station component life,” the vendor added.

However, the industry will need to do much more amid rampant data consumption and increased investments in data centers.
