7. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 7 Scenario: Corporate (Office) Higher bandwidth Higher security Portability (Nomadic service) Network management

8. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 8 Scenario: Public Accounting –Subscriber identification –Service level agreement / QoS Higher security –Authentication –Encryption Network management

9. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 9 Scenario: Public (Hot Spot) Seamless mobility –Inter/Intra hot spot –Inter operator –Inter system “hot spot” and “Cellular” –Terminal identification: IPv6? Higher security

10. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 10 Scenario: Public (Car) Higher mobility –High speed –Less predictable Location information: GPS? Reliability –Temperature –Shock resistance

11. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 11 Scenario: Public (Train) Higher mobility –High speed –Predictable Many users –High density –Move simultaneously Handover nightmare Seamless roaming –Inter/Intra train –Inter train and platform –Inter train operator

12. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 12 Scenario: Public (On the Move) Seamless roaming –Cellular deployment –Hot spot + 3G –Inter scenario roaming

13. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 13 Scenario: Public (City Centre) Features for “hot spot” and “on the move” plus… Match making –One time communication Ad-hoc? –Anonymous communication Privacy –Special interest group Location based services

14. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 14 Scenario: Public (Easy Pass) Quick authentication Strong security -car,ticket,door,PC-

15. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 15 Scenario: PAN Functionality integration –e.g. PAN devices plus WAN functionality (PDA plus cell-phone) Plug and Play

16. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 16 Open Questions Do we want single standard and/or Roamable standards? Either or Both? Do we have more scenarios? –Airplane? Rural area? Under the sea/ground? In the space? Do some of us need to stick to universal service? –Some operators yes…? Do we need to collaborate with other bodies such as 3GPP, IETF, etc. Are we talking “When”? Spectrum discussion? –ISM bands? UWB? 5GHz? New bands?

17. doc.: IEEE 802.11-02/149r0 Submission March, 2002 Jun Hirano, Matsushita CommunicationSlide 17 Conclusion Market requires more functionality and performance. Current requirements discussed in WNG are not enough. GAN concept depicts more requirements. –Global seamless roaming –High mobility GAN concept is proposed with open questions for discussion base within WNG.
