For every dollar spent on PSTN networks, it takes at least another dollar to cool them, he said. “While we're seeing optimization in every other area” of the telecom industry, “all we're seeing is the cost of energy going up,” Walsh said. Right now the PSTN consumes 12 billion kilowatt-hours of power each year, Walsh said. A 70 percent reduction in power usage would save 8.4 billion kWh annually. “These are thousands of generators and elimination of the need for lots of new power plants if we could just sunset the PSTN,” Walsh said. That equates to $1.3 billion in savings annually, which is “enough money to completely transform most of the networks that we're living with,” he said. “There’s a huge opportunity now to move from the old legacy networks to a whole completely new infrastructure,” financed by savings from upgrading the infrastructure, he said. “What we're calling this is a sunrise of next-generation networks.”
