Wi-Fi Calling is relatively new – and then, not really. In 2014, Apple’s launch of iOS 8 with embedded Wi-Fi Calling marked a milestone for voice calling with mobile devices, despite several years of Voice over Wi-Fi services in various guises preceding iOS 8.

Aptilo Networks – a leading provider of carrier-class systems to manage data services with advanced functions for authentication, policy control and charging – has released a White Paper titled “Seamless Next Generation Wi-Fi Calling”, which is written by Allan Greve of tefficient.

Next generation Wi-Fi Calling has created a paradigm shift in how mobile operators can provide indoor coverage for voice services. The improved customer experience has a profound impact on customer retention. The white paper aims to give an overview of next generation Wi-Fi Calling both in commercial and technical terms and looks at Wi-Fi Calling from the perspectives of users, operators, handset manufacturers and OTT players.
