The continuing growth in smartphone shipments will, according to Juniper Research, see mobile VoIP calls rise dramatically from 15 billion minutes in 2010 to a colossal 470.6 billion by 2015. The company believes this shift could potentially damage traditional mobile operators in the process.
A study undertaken by Juniper claims that mobile VoIP will go through explosive growth in the next five years, threatening the very existence of today's mobile operators.
"Wi-Fi mobile VoIP is potentially the most damaging of all VoIP traffic as it bypasses the mobile networks altogether," said the firm. "We forecast that mobile VoIP over Wi-Fi will cost operators US$5 billion globally by 2015." Article
