2. doc.: IEEE 802.11-03/828r2 Submission November 2003 Stephen McCann, Siemens Roke ManorSlide 2 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.

Mobility –same again, IETF, but remember that Fast Roaming SG is looking at ESS roaming.

5. doc.: IEEE 802.11-03/828r2 Submission November 2003 Stephen McCann, Siemens Roke ManorSlide 5 Requirements What is required for a public access hotspot standard ? Are all the pieces of the Jigsaw known ? Impact on 802.11. Is there a generic interface model to external networks ? Who cares ?

6. doc.: IEEE 802.11-03/828r2 Submission November 2003 Stephen McCann, Siemens Roke ManorSlide 6 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?

8. doc.: IEEE 802.11-03/828r2 Submission November 2003 Stephen McCann, Siemens Roke ManorSlide 8 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 –Does the terminal have to change it’s behaviour between different networks. –Are their solutions compatible with the output of TGe, TGf, TGi, TGk and TGn.

9. doc.: IEEE 802.11-03/828r2 Submission November 2003 Stephen McCann, Siemens Roke ManorSlide 9 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.
