In Denmark, Telenor had for years tried to exploit this unresolved energy-saving potential. At a certain point, they faced a problem they didn’t manage to solve on their own, as Mads Sørensen, Business Architect at Telenor Denmark, explains:
“We had implemented a power-saving feature in our network, which, in short, was supposed to adjust the power usage in all of our 12,000 sectors based on capacity demand. Unfortunately, the feature did not manage to adjust the power saving automatically. To manually set an activation for each of the 12,000 sectors would be impossible considering the time consumption. Setting a fixed power-saving mode for all the sectors would have to be done very conservatively, meaning the loss of huge power saving potential,” he says.
It became apparent to Sørensen and his colleagues that in order to harvest the full potential of this feature, they needed to implement some sort of automation. That’s when Sørensen reached out to Telenor Research.
“As we started digging into the issue, we realised that historical data and analytics could be used to adapt power-saving windows individually for each sector depending on what the specific traffic profile looked like,” Edvardsen says.
With that, the seed that would grow into Green Radio had been sown.
