Energy inefficiency could kill pure cellular

In a piece of research that could have implications for the future of mobile broadband, a US analyst firm has claimed that new mobile applications will make pure cellular technology too energy-inefficient to be practical in the future.

Noting that energy costs represent the third most expensive operating expense (OPEX) for carriers today — and that energy costs continue to fluctuate and could rise — the authors claim that the increase in data traffic resulting from the rise of mobile broadband “will push per-subscriber energy OPEX for cellular solutions past acceptable barriers”.
