2013 marked a rapid increase in interest to improve cellular to Wi-Fi interoperability – not just from mobile operators, but also from cable operators, fixed line operators and enterprises. The interest is truly global as organizations in every region are developing strategies to leverage Wi-Fi for a variety of reasons, including network congestion relief, improved in-building coverage, and ability to offer lower cost wireless service plans. However, in order to achieve truly seamless interoperability across heterogeneous networks from any provider, the industry needs to resolve challenges associated with connectivity, authentication, session persistence and traffic management. This is the objective of several emerging industry standards, including a set being developed by the 3rd Generation Partnership Project (3GPP) known as Access Network Discovery and Selection Function, or ANDSF.
