subject: Increased Focus On Network Power Consumption To Lower Opex, Go Green [print this page] Introduction Introduction
In this first network equipment power benchmarking report, Ovum surveyed major network operators and systems vendors to gauge their views on issues and trends for power consumption in public networks.
Highlights
One common theme among telcos is clear - they are all looking to provide an efficient next-generation network on which they can offer high-quality value-added services (VASs) to their customers. Telecoms operators are faced with a string of challenges from defending their core fixed revenues to generating growth from new wave services and international operations.
