Usage Scenarios for ESS Mesh Network Month 2002 doc.: IEEE 802.11-02/xxxr0 May 2004 Usage Scenarios for ESS Mesh Network Hidenori AOKI, Koji OMAE and Yoichi MATSUMOTO NTT DoCoMo (aokihid@nttdocomo.co.jp) H.Aoki, K.Omae and Y. Matsumoto - NTT DoCoMo John Doe, His Company

Key technology & Usage Scenarios May 2004 Key technology & Usage Scenarios Key technologies Layer2 Mesh Routing protocol MAC enhancement Security Usage Scenarios Home network Enterprise network Hotspot backhaul H.Aoki, K.Omae and Y. Matsumoto - NTT DoCoMo

Home network(1/2) Devices Application Requirements May 2004 Home network(1/2) Devices WLAN AP, Desktop PC, Laptop PC, TV, Settop box ,DVD/VCR player.. Application HDTV, VoIP, Web browsing, E-mail.. Requirements High throughput Radio aware mesh routing Need scalability for multi radio support Low delay QoS support for AP-AP link Security mechanism for small network H.Aoki, K.Omae and Y. Matsumoto - NTT DoCoMo

May 2004 Home network(2/2) ESS mesh functionality will be implemented into CE devices, not limited to Access Point Device Consumer devices may have a single WLAN interface One WLAN interface may handle both of “AP-STA link” and “AP-AP link” simultaneously. ESS mesh should support low mobility (walking speed) Satisfactory Connection throughout the entire home environment. Easy user interface (not as a part of infrastructure but end-user device) H.Aoki, K.Omae and Y. Matsumoto - NTT DoCoMo

Enterprise network(1/2) May 2004 Enterprise network(1/2) Devices DesktopPC, Laptop, Copying Machine, Fax, Printer, Projector Application Web browsing, VoIP, File sharing, E-mail.. Wired LAN H.Aoki, K.Omae and Y. Matsumoto - NTT DoCoMo

Enterprise network(2/2) May 2004 Enterprise network(2/2) There will be multiple ESS mesh domain in the network. Each ESS mesh domains are connected by IEEE802.3 Wired LAN. Conformance with IEEE802.3 newtork VLAN support Multiple entrances to Wired LAN Wired LAN（802.3) ESS mesh #1 First floor ESS mesh #2 Second floor H.Aoki, K.Omae and Y. Matsumoto - NTT DoCoMo

Summary Need to include CE devices in the ESS mesh usage scenarios. Month 2002 doc.: IEEE 802.11-02/xxxr0 May 2004 Summary Need to include CE devices in the ESS mesh usage scenarios. Suggest to start at reasonable size network such as Home, Enterprise network. H.Aoki, K.Omae and Y. Matsumoto - NTT DoCoMo John Doe, His Company
