2 SysArchUseCase.PPT/ Jan 2004 / rev2 IEEE Media Independent Handover Use Case 1 David has a multi-radio device. He connects to his Intranet via IEEE g. He leaves his office and crosses the campus to another building. In between buildings there is Intranet coverage via IEEE D

3 SysArchUseCase.PPT/ Jan 2004 / rev2 IEEE Media Independent Handover Use Case 2 David has a multi-radio device. He connects to his Intranet via IEEE g. He leaves from his office and continues his session via GPRS. D

4 SysArchUseCase.PPT/ Jan 2004 / rev2 IEEE Media Independent Handover Use Case 3 David has a single radio device. He connects to the Internet via a hotel public hotspot IEEE g in his room. He walks to the conference which has a different ESS and continues his session. D

5 SysArchUseCase.PPT/ Jan 2004 / rev2 IEEE Media Independent Handover Use Case 4 David is unassociated. He is walking in the airport and there are a variety of SSIDs visible. Which network should he pick? D
