Orange's deputy chief executive Vivek Badrinath on Wednesday warned that operators' energy consumption is spiralling as they upgrade their networks to meet increased bandwidth demand.
He said during a panel session at Broadband World Forum in Amsterdam that operators are generally doing a good job of maintaining close control of capital and operational expenses as they roll out higher-capacity networks.
"But there is one line item that's not under control, and that is energy consumption," claimed Badrinath, who said that energy consumption needs to come down as bandwidth demand goes up.
"This is a wake-up call to the industry. Energy consumption is not under control," he reiterated.
As well as proclamations about the carbon footprints of networks, Badrinath also called on vendors to make sure their kit generates useful data that can be fed back into the operator.
"Produce data, please, and put it in a place where we can find it easily and use it, because data is going to drive a new wave of customer experience management," he said.
