Key Messages to Take Away (1)
• 802.21 Already provides support for handovers
between bidirectional link technologies (e.g. 802.16,
802.11, Cellular)
• New SG created in 802.21 to address the case when
handover is made from/to unidirectional (e.g.
downlink only) technologies

Key Messages to Take Away (2)
• Converged devices including both types of
technologies already exist
• This is a market opportunity for 802.16 – WiMAX !!
•
E.g. SK Telecom in Korea has both WiBro and DMB
networks

Next Steps
• Finish PAR/5C and get it approved by
• Form a new TG in 802.21 to amend the baseline
specification to support handovers with downlink-only
technologies
