The proliferation of mobile applications has increased the amount of data in the 4G mobile network. With the adoption of smartphones and broadband services such as video streaming, cellular network resources are becoming increasingly constrained.

Wi-Fi technology is ideally positioned to add capacity to the cellular network. It is necessary to improve the interworking between the 4G mobile network and the Wi-Fi network in order to offer a global and consistent broadband access for the end user.

The integration of Wi-Fi access to the 4G mobile network has an impact on the architecture of the core network, which has several variants. These variants depend on whether the Wi-Fi access is deemed trusted or untrusted by the operator, and whether the mobility is managed by the network or the mobile.

This book also covers the aggregation of LTE and Wi-Fi channels, which is another approach that does not impact the structure of the core network. LAA and LWA are mechanisms for which the radio station is the anchor point for channel aggregation.
