3. Use Case Scenario Microwave3GWiFi

4. How it all began: EU Project CARMEN Network operators Equipment manufacturers Academia / research institutes

5. Additional Use Case Scenarios “Stadium”, proposed by BT  low-cost, short-term provisioning of additional wireless access capacity  triple-play QoS requirements “Emergency Response Support”, proposed by DT  severe capacity constraints  intermittent connectivity to core network  sub-optimal node placement  focus on group-communication Internet

6. Goals Enable such use case scenarios in a media independent way Limit the scope to Neighbor discovery Radio configuration Monitoring Resource Reservation Develop working testbed

7. Why IEEE 802.21? It offers media independence It specifies many of the needed primitives already It offers the required communication mechanisms However, there are still points missing to enable wireless network management and some new primitives would be needed

8. Required Functionality (Samples) Events – Link_QOS_Changed – Link_Detected – Node_Going_Down Commands – Link_Get_Parameters – Link_Scan – Link_Set_Parameters Information Wireless Networks

9. Required Functionality (Samples) Events – Link_QOS_Changed – Link_Detected – Node_Going_Down Commands – Link_Get_Parameters – Link_Scan – Link_Set_Parameters Information Link_Parameters_Report Link_Detected (diff. link) - Link_Get_Parameters Link_Actions - MIIS Wireless NetworksIEEE 802.21 (MIH) reusemodifyadd

10. Clearly Identified Extension Areas Node and topology discovery Propagate network specific information (topology, capabilities of individual nodes, actual/possible settings...) Detect new neighbors Registration of new nodes Radio configuration Detect radio interfaces and capabilities Get/set current values Monitoring Resource constraints Per-flow granularity for handovers

11. LinkNet Macha Project in Zambia Villages and the houses within those villages are scattered across a large land No wired communication No reliable power supply Limited hardware resources Limited budget Target: Deploy a country-wide heterogeneous wireless backhaul which is reliable enough to provide affordable connection throughout the country First devices have been deployed by Fraunhofer Institute in September 2009

14. Conclusion Heterogeneous wireless networks are a promising solution in a number of use cases Required functionality is covered to a large extent by IEEE 802.21 due to its media independence Consortium of companies/research institutes have investigated and are currently implementing a heterogeneous backhaul using IEEE 802.21 extension

Conclusion Heterogeneous wireless networks are a promising solution in a number of use cases Required functionality is covered to a large extent by IEEE 802.21 due to its media independence Consortium of companies/research institutes have investigated and are currently implementing a heterogeneous backhaul using IEEE 802.21 extension There is a need for a IEEE 802.21 Study Group to further elaborate and attract more stakeholders

16. Motion “ Move to form an IEEE 802.21 Study Group to examine issues related to supporting management of heterogeneous wireless networks (as per ref: 21-09-0187-00-0000), and if necessary create a PAR and five criteria to form a new Task Group." Mover: Second: Yes: No: Abstain
