Why IPTV over WiMAX?

• The features of the WiMAX is multicast
  capability.
• Increase the Number of Subscribers
• Scheduled Live Content and Quality Assurance.
• Mobility.

13
Challenge

• WiMAX Bandwidth.
• Instance Channel Change.
• Mobility.
• Jitter.
• Overhead.
• Transceiver Design.
• Power Consumption.

Protocol Stack
16
System Design(1)

• VLAN divided by IP address
• Multicast Group divided by VLAN and Channel
• Select one prefix group(225)first byte
• Reservedsecond byte
• VLANthird byte
• Channelfourth byte

17
System Design(2)

• In the third byte, Define 255 is broadcast.
• WiMAX Quality of Service Setup

18
System Design(3)

• WiMAX Packet Identify Rule
• Service Class Creation
• Packet Identify Rule
• Service Flow Class
• Subscriber Station Class
• RelationshipSS Class ? SF Class ? PIR
• Subscriber Station List
