Even if mobile carriers introduce truly unlimited plans and excellent indoor coverage everywhere, they will also need to open extensive APIs to enterprises if they want to entice them away from Wi-Fi. Enterprises (including businesses with public access areas such as shopping centres and stadiums) want the extra control and information (such as the location of consumers as they move through shopping centres) they have with their Wi-Fi networks that they can get today. Conversely, the mobile carriers will probably be wanting to incorporate the Wi-Fi access into their mobile networks as another access type. Apart from the control aspect, having combined and coordinated access to both licensed and unlicensed spectrum allows a better infrastructure cost to capacity tradeoff.
