How six features and capabilities of DC power systems can lower the total cost of ownership of 4G/LTE networks. Published February 2014.
Carriers spend an estimated $36 billion globally on energy expense to keep wireless base stations online. That includes $21.9 billion in grid power, according to ABI Research, and another $14.6 million in gasoline and diesel for gen-sets according to the GSMA. That cost has risen dramatically in recent years as energy prices continue to climb and the number of base stations increases.
The high cost of energy explains why the use of alternative energies to power base stations is on the rise. But it doesn’t explain why some carriers focus solely on getting the lowest capital cost in procuring the DC power systems that manage this power. There has been so much innovation in recent years that DC power systems are far from being commodity purchases.
Given this new technology, a total cost of ownership analysis for buying new systems is a balanced way to consider the purchase price and the ongoing cost elements. With a two to five-year payback on these systems, and a ten- year or longer useful life, it could be argued that maximizing these cost-saving features is even more important than seeking a lower capital cost.
This whitepaper will look at the key ways that a DC power system can save money for wireless carriers, including high efficiency, support for alternative energy, intelligent monitoring power density and design for reliability.
