Goal and Scope
• Wireless Broadband Access Technologies
– IEEE develops 802.16 standards to support the deployment of
broadband wireless metropolitan area networks.
– WiMAX certifies interoperability of broadband wireless products.
– WiBro (Wireless Broadband), Korea effort is also based on the
802.16.
• Goal of this Draft
– Recently, broadband wireless access network is emerging for
wireless communication for user requirements such as high
quality data/voice service, fast mobility, wide coverage, etc.
– The draft extends [bb-deployment- scenarios] and uses its
structure and common terminology.
– Useful for IPv6 ISPs who want to adopt Wireless Broadband
Access Networks.

Scenario A
• A BS is integrated with a router, composing one box
in view of implementation.
• A subnet consists of only single BS/router and single
MS.

• A subnet consists of only single BS/AR and multiple
MSs.

• A subnet consists of only single BS and single router
and multiple MSs.

Things to Do
• According to each scenarios, the following
considerations was discussed in this draft.
–
–
–
–
IPv6 Related Infrastructure Changes
Addressing
IPv6 Control and Data Transport
Routing
• Also, IPv6 Multicast, QoS, Security, Network
Management changes was described.

Next Steps
• Feel of Room Here
– Adopt this draft as a new WG document ?
• The best way was to add this material into [bbdeployment- scenarios] , but it is too late at this time.
• So, publish it as a separate document.
– It covers scenarios and deployment issues, while
16ng will cover protocol issues.
