Interview: Ericsson CEO on the role of Wi-Fi in mobile

While there is a groundswell of enthusiasm for Wi-Fi as a mobile data alternative to cellular, Ericsson CEO Hans Vestberg says there is a limit to what Wi-Fi can accomplish. Wi-Fi will have a role, but it will be one connection option among many.

We already use Wi-Fi more than cellular; Why not continue the trend?

In terms of mobile data, our smartphones are far more reliant on Wi-Fi. So why are carriers so single-mindedly focused on acquiring new licensed spectrum and building expensive 3G and 4G networks, when they could implement more Wi-Fi and tap into other sources of unlicensed spectrum?
