The adoption of smartphones has had as a corollary the use of companies that require streaming, similar to video streaming, which is a constraint for the 4G cellular community. The integration of the community of Wi-Fi hotspots deployed by the operators provides capability to the 4G cellular community.
The use of Wi-Fi know-how in provider networks is the results of developments coordinated by the IEEE, WFA and WBA standardization our bodies. For its half, the 3GPP standardization physique has been working to combine Wi-Fi know-how into the 4G cellular community.
The first a part of this e book presents the traits of the Wi-Fi radio interface. The completely different IEEE 802.11b / g / n / ac bodily layers characterize the implementation in the 2.4 GHz ISM frequency bands and U- NII at 5 GHz. The MAC layer defines a lot of media entry procedures similar to scanning, associating, or transferring knowledge.
The second a part of this e book offers with the structure of the 4G community based mostly on the Wi-Fi interface. This structure defines a number of fashions corresponding, on the one hand, to Wi-Fi entry managed or not, On the different hand, to a handover managed by the community or by the cellular. The integration of Wi-Fi know-how resulted in a redefinition of attachment and session set-up procedures.
Smartphones have the means to activate concurrently the two radio interfaces, LTE and Wi-Fi, which permits to direct sure companies to one and / or the different of the interfaces. The ANDSF and HotSpot 2.0 features present the cellular with guidelines for community choice and visitors management to decide which visitors is to be routed to what kind of interface.
