2. Key Messages to Take Away (1)
Already provides support for handovers between bidirectional link technologies (e.g , , Cellular)
New SG created in to address the case when handover is made from/to unidirectional (e.g. downlink only) technologies

4. Key Messages to Take Away (2)
Converged devices including both types of technologies already exist
This is a market opportunity for – WiMAX !!
E.g. SK Telecom in Korea has both WiBro and DMB networks

5. Next Steps Finish PAR/5C and get it approved by
Form a new TG in to amend the baseline specification to support handovers with downlink-only technologies
