IEEE 802.11 & WIG
• Plenary Motion Approved in 2002
– Move that the WNG Standing Committee
requests the 802.11 WG to accept the
invitation from ETSI-BRAN and MMAC
to participate in the “WLAN – 3G and
other Public Access networks
“interworking” (WIG) project.
Submission

What is this about ?
• To establish a joint-effort between 802.11
and ETSI BRAN/MMAC HSWA for the
interworking of WLANs to 3G Cellular
systems.
• 802.11 should be represented by its own
interworking group.

Previous work
• At engineering level, TGi already has
similar approach to external authentication
(EAPoL) to that of other WLAN standards
(e.g. Hiperlan & HiSWAN)
• Previous interworking activities done by
ETSI BRAN and MMAC HSWA have
similar approach to that of 802.1x

802.11 Intended Output ?
• Necessity to align interworking work from
TGe, TGi, WNG and 802.1
• Procedural requirement to establish some
kind of interworking group within 802.11 to
address these issues.
Submission

WIG Intended Output ?
• WIG Baseline Document
• Common text, which will then be passed
based to recognised WLAN standards
bodies (ETSI, IEEE & MMAC) for their
regulatory approval.
• WIG cannot NOT approve final output
Submission

Why bother ?
• To create a world wide standard for WLAN
interworking with Cellular and Public
Access networks.
• To encourage the proliferation of world
wide WLAN hotspots, regardless of local
regulatory constraints.
Submission

WIG Scope
• To be an integral part in the production of a
generically applicable interworking standard for
WWAN and other public networks. The standard is to
be applicable for IEEE 802.11 family, MMAC
HiSWAN family and ETSI HIPERLAN/2
• To be the point of resolution for ETSI, IEEE and
MMAC on issues related to interworking with WWAN
and other public networks.
• To be the single point of contact for the above
mentioned WLAN standards on questions related to
interworking with WWAN and other public networks.
Submission

How to do this work ?
• Through WLAN Interworking Group
(WIG) meetings
• 3 times a year, co-hosted at IEEE 802.11,
ETSI BRAN & MMAC HSWA meetings
• Interim discussions at other meetings in
between, to progress technical aspects (e.g.
IEEE 802.11 Interworking group)

IEEE 802.11 PAR
• No specific group in IEEE802.11 dedicated
to interworking issues
• Is WNG official representation in WIG ?
• Many external activities in this area, WIG,
3GPP, GSMA, WiFi Alliance all addressing
interworking issues.
• Bits of interworking done in WNG, TGi,
TGe, 802.1 (802.1x and 802.1aa)

– Technical contributions
• WIG Baseline document update
• Conformance with 802.1x/802.1aa issues
• Conformance with 3GPP SA2 issues
– Editorial matters

5 line PAR Scope
• The scope of the project is to enhance the 802.11 standard
and amendments, through the generation of a standard to
add interworking capability to both cellular and external IP
based networks including the Internet. This project will
conform with similar proposal specified by both Japanese
(MMAC) and European (ETSI) standardization bodies
Submission
Slide 16
Stephen McCann, Siemens Roke Manor

5 line PAR purpose
• To generate two output documents to enhance the 802.11
standard and amendments :
– Cellular and external IP network interworking requirements
– Cellular and external IP network interworking reference
architecture description
• These outputs will define and specify the addition of
specific interfaces to deal with interworking security,
accounting and resource allocation between an 802.11
system and the aforementioned external networks

PAR extra notes
• The scope of this project is to develop a standard for the interworking
of 802.11 with cellular and external IP networks. 802.11 have decided
to participate within the Wireless Interworking Group which aims to
produce a Generic Baseline Document for the interworking of all
WLANs with cellular and external IP networks. It is therefore
necessary for 802.11 to create a standard which specifies the
requirements and interfaces between 802.11 and the WIG output
document.
• The intended WIG baseline document can not be implanted with the
current amendments to 802.11 (e.g. 802.11i). This new standard works
on the necessary new interfaces which will enable this to occur.
