The coming challenge for Wi-Fi offload is to provide a converged network solution for a seamless, transparent and better user experience. The user will not have to interact with its smartphone or mobile device in any way to switch from 3G/LTE to Wi-Fi. The data stream will even be able to use both connections at the same time depending on QoS requirements.
This short guide explores the technical aspects of Wi-Fi offload architecture and its related capabilities. It is presenting the different types of possible integration into existing mobile networks to provide a viable and efficient way to offload subscriber traffic. It concludes with an overview on testing methods.
