2. Questions (1 of 3) What groups are interested in conducting mobility-related experiments on WiMAX? What kind of experiments do these groups intend to perform? What handover functionality is needed for these experiments at layer 2? What mobility management functionality is needed to conduct these experiments at layer 3? –Is MobileIP v4 adequate? Is there interest for MobileIP v6?

3. Questions (2 of 3) What type of measurement capabilities are needed to conduct mobility-related experiments? –Mobility management delays at layer2, layer 3 –Impact of QoS Do you need cross-technology handover functions? –WiMAX to WiFi and vice versa What kind of support does Airspan provide in their software?
