Objectives Study Group Proposal Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Objectives Study Group Proposal Overall goal should be to define a standards ‚story‘ of how hotspots can be constructed, in a consistent and interoperable manner.

Jigsaw Security (TGi) QoS (TGe only provides QoS over the air) Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Jigsaw Security (TGi) QoS (TGe only provides QoS over the air) Handoff (but not 802 handoff) Policy Network layer issue, IETF, but does it impact IEEE 802.11 ? Mobility same again, IETF, but remember that Fast Roaming SG is looking at ESS roaming. Stephen McCann, Siemens Roke Manor John Doe, His Company

Requirements What is required for a public access hotspot standard? Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Requirements What is required for a public access hotspot standard? Are all the pieces of the Jigsaw known ? Is there a generic interface model to external networks ? Who cares ? Stephen McCann, Siemens Roke Manor John Doe, His Company

Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Standards/Test Plans Technology and therefore interfaces must be defined by standardisation body. External interfaces should be defined by same body which defined the technology where possible. Test plans should be defined by industry. If test plans start to re-define the interfaces to the technology, where is the line drawn between technology definition and testing? Stephen McCann, Siemens Roke Manor John Doe, His Company

Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Who cares Who should standardise an IEEE 802.11 public access solution. Should this be left to 3GPP and/or 3GPP2 What happens if their solutions impact the MAC layer. Are their solutions compatible with the output of TGe, TGf, TGi, TGk and TGn. Stephen McCann, Siemens Roke Manor John Doe, His Company

Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Way forward IEEE 802.11 requires some extra work in the DS to define external interworking TGe, TGf, TGi and TGk have started to do this already with functional definitions Accounting/Charging ? Policy ? Should assess WFA, GSMA, 3GPP & 3GPP2 requirements placed on IEEE 802.11 Stephen McCann, Siemens Roke Manor John Doe, His Company

Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Study Group Scope The scope of the study group is to consider whether there is a requirement to enhance the IEEE 802.11 standard (and amendments), to add interworking capability to both cellular and external IP based networks. The intention is to re-use the output of existing Task Groups to form a complete interworking solution, and to fill in any gaps. Stephen McCann, Siemens Roke Manor John Doe, His Company

Month 2002 doc.: IEEE 802.11-02/xxxr0 November 2003 Motion That an IEEE 802.11 Study Group be formed, to determine whether there is a requirement to enhance the IEEE 802.11 standard (and amendments), to add interworking capability to both cellular and external IP based networks. If it is determined necessary, the study group will then create a PAR and 5Criteria for further work within a Task Group. Stephen McCann, Siemens Roke Manor John Doe, His Company
