2 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 2 This presentation is made to the IEEE WG on behalf of the Wi-Fi Alliance Andrew Myles, the presenter is: Employed by Cisco Systems Affiliated with Cisco Systems Chairman of the Wi-Fi Alliance Presenting on behalf of the Wi-Fi Alliance Presenting in response to an invitation by the WG Chair

3 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 3 Research shows (aka Wi-Fi) is becoming an essential part of our everyday lives Research in the US reveals some factoids about the impact of Wi-Fi … 80% say Wi-Fi is more essential than their iPod 81% would rather see their favourite team lose than give up Wi-Fi for a week 90% would rather do without their daily Starbucks than their Wi-Fi … the bottom line is that Wi-Fi is affecting real people in their everyday lives Source: WFA/Kelton Research, July & October 2006

4 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 4 Wi-Fi has become popular based on products that are not optimised for wireless use ….. with apologies to all those in the PC industry Not very usable while on the move Not really suitable for many voice applications Until recently, laptops were mainly an enterprise style product

5 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 5 … and yet the Wi-Fi market reached over 200 million chipsets per year in 2006 In 1997, the first IEEE standard was ratified In 2005, over 150 million Wi-Fi devices were sold In 2006, over 200 million Wi-Fi devices were sold (33% growth rate) Enterprise APs Home/SOHO CE Phones PCs Devices (million) Source: In-Stat

6 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 6 Wi-Fi is now being implemented in a wide variety of more interesting devices … Microsoft Zune Sony myloNikon Coolpix Sony PS3 Nabaztag Nokia N series

7 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 7 … including lots of Wi-Fi & Wi-Fi/cellular converged phone devices …

8 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 8 … with some of the new devices actually used for voice (and not just data) … Numerous Wi-Fi carrier voice and data deployments are underway, and others expected during 2007 and 2008 Wi-Fi with UMA is the predominant voice approach today, although SIP solutions also exist Examples of voice deployments include: –BT Fusion:voice & data in the home/office network at more than 2,000 Openzone hotspots –Orange Unik for Professionals: provides Wi-Fi to GSM handoff, and includes unlimited use for Wi-Fi calls –NTT DoCoMo: SIP-based voice for large enterprise customers

9 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 9 … based on access in many locations outside the home or office … 143k+ hot spots in 132 countries –Source: JiWire (12 March 2007) –Other sources indicate 200k+ hot spots 500+ muni deployments in 29 countries –Source: Tropos & WFA 82% of US hotels offer Wi-Fi –Source: American Hotel & Lodging Assn Melbourne

10 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 10 … which means the promise of one billion chipsets sold in a year might not be far off! Both CE and Voice are forecast to make a big impact by 2010 They will enable even more use of Wi-Fi both in all market segments One billion chipsets is forecast by 2012 CE Voice Not far from 1B!

11 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 11 This historical (and future) success is based on the partnership of the WG & the Wi-Fi Alliance Standards developmentProduct certification

12 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 12 Like all great partnerships the IEEE WG and the Wi-Fi Alliance need to “work on it” Like all great partners/marriages the WFA & the WG have: –Had rocky moments –eg liaison presentation in Nov 06 –Had disagreements –eg WFA introduction of “draft 11n” and WMM –Imperfections on both sides –eg process issues But ultimately the WFA & the WG need each other The rest of this presentation is based on the idea that WFA & the WG can strengthen the relationship with: –Communications –Honesty –Learning from each other & history

13 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 13 The agenda is focused on open communications between the WFA & the IEEE G Who is the WFA? What, who & how What have the WFA done in the past? Lessons learnt What can the IEEE WG do to help? What are the WFA planning to do in the future? Plans & possibilities

14 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 14 The Wi-Fi Alliance is an international trade & certification association for products The Wi-Fi Alliance Is a non-profit international trade association (ITA) that: Certifies the interoperability of IEEE based products using eleven independent test labs in seven countries (over 3,400 so far) Facilitates collaboration within the ecosystem: manufacturers, standard bodies, regulators, service providers, and carriers Acts as a thought leader on all issues related to Wi-Fi products and technology

15 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 15 The Wi-Fi Alliance has over 300 members with representation from across the ecosystem Full list of member companies at Sponsors Sample regular members

16 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 16 The Wi-Fi Alliance is truly international with only 44% of members based in the Americas Europe 15% Asia-Pacific 41% Americas 44% … and we schedule one meeting per year per region

17 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 17 Two sites: Japan One site: Korea Three sites: Taiwan One site: China Three sites: EU Two sites: USA One site: India One site: USA WFA R&D California 2007 One site: Taiwan Pre-cert lab Certification lab The Wi-Fi Alliance has authorised certification labs in seven countries

18 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 18 The primary goal of the Wi-Fi Alliance is ensure interoperability for customers & vendors The goal is to help ensure that based products from multiple vendors work together to: –Reduce returns and customers support for vendors –Ensure an excellent user experience for customers This is achieved by testing products against a test-bed of “golden products”: –Mostly using “low bar” performance testing –With some conformance testing –And some performance testing This test bed approach is a pragmatic solution well suited to the WLAN industry that provides a good compromise between: –Full conformance testing –Cost of testing

19 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 19 The WFA uses a governance model based on work done in Task Groups with review by the BoD Law TG Self selected group of members, often with a commercial interest in the activities of the TG Quite rightly, they do not necessarily have the interest of all members at “top of mind” BoD & TGs counterbalance each other, in a way that other systems would not BoD Directors, although appointed by Sponsors, must act in interests of all members (“fiduciary duty”) The BoD acts as “house of review” to ensure recommendations from TGs make sense for the WFA Director responsibilities Act in compliance with the law Act in the best interests of the WFA … Observation: there is no equivalent body in the IEEE WG, which sometimes deadlocks with no mechanism for resolution

20 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 20 The agenda is focused on open communications between the WFA & the IEEE G Who is the WFA? What, who & how What have the WFA done in the past? Lessons learnt What can the IEEE WG do to help? What are the WFA planning to do in the future? Plans & possibilities

21 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 21 The WFA have a continuing pipeline of certifications, from which we continue to “learn” Market development Another time Influencing Another time Certifications When? Status? Number? Observations? Lessons? These lessons can be used to draw a variety of conclusions In this presentation, we will explore some possibilities However, final conclusions are “homework” for all of us

22 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 22 The Wi-Fi Alliance currently has certifications for PHY, security, QoS, spectrum man. & convergence … PHYs b (2.4GHz) a (5GHz) g (2.4GHz) Security WPA™ - Personal/Enterprise WPA2™ - Personal/Enterprise Extended EAP testing Wi-Fi Protected Setup™ Quality of Service WMM™ WMM™ Power Save Spectrum management h+d Convergence CWG-RF

23 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 23 … and there have been almost 3,500 products certified by the WFA since 2000

24 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 24 The b certification seeded the incredible success of the Wi-Fi industry Name b Introduced April 2000 (standard ratified Sept 99) Status Mandatory (if implemented) Certifications 2,746 (May 2006) Observations PHY & MAC certification based b and DCF MAC b is a wildly successful certification that was the basis of the early success of Wi-Fi b was the right standard/product at the right time Lessons for WFA & IEEE Simple & interoperable products that meet a need are “deadly” in the market

25 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 25 The a standard and certification was probably “before its time” Name a Introduced October 2002 (standard ratified Sept 99) Status Mandatory (if implemented) Certifications 556 (May 2006) Observations PHY & MAC certification based a and DCF MAC a was not as successful in the market as originally hoped –Only 556x a certifications vs 2,746x b certifications –802.11a’s problem was that b/g based on 2.4GHz was “good enough” for a long time Lessons for WFA & IEEE Good standards and proven interoperability are not enough for success

26 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 26 The g certification leveraged b’s success in 2.4GHz and a’s technology Name g Introduced July 2003 (standard ratified June 03) Status Mandatory (if implemented) Certifications 1,932 (May 2006) Observations PHY & MAC certification based g and DCF MAC g is a wildly successful certification that has leveraged b’s success in 2.4GHz and a’s technology Lessons for WFA & IEEE The combination of backward compatibility, improved performance and an easy upgrade path is usually better

27 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 27 The WPA certification addressed the “WEP issue” in partnership with the IEEE WG Name Wi-Fi Protected Access –WPA – Personal –WPA - Enterprise Introduced April 2003 (standard ratified June 04) Status Mandatory Certifications Personal: 2,076 (May 2006) Enterprise: 1,709 (May 2006) Observations WPA is based on the TKIP aspects of i –“Personal” is based on PSK –“Enterprise” is based on 802.1X WPA was introduced (in partnership with IEEE) well before i was ratified to address the “WEP debacle” Lessons for WFA & IEEE The option to configure security operation is a “threshold attribute” WFA & IEEE can work together on pre-ratification certifications

28 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 28 The WPA2 certification satisfied the basic security requirements of WLANs Name Wi-Fi Protected Access 2 –WPA2 – Personal –WPA2 - Enterprise Introduced September 2004 (standard ratified June 04) Status Mandatory as of March 2006 Certifications Personal: 1,011 (May 2006) Enterprise: 811 (May 2006) Observations WPA2 is based on the CCMP part of i –Personal is based on PSK –Enterprise is based on 802.1X Lessons for WFA & IEEE It is always better to let security experts design security protocols Note: this lesson probably applies to all elements of standards development

29 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 29 The extended EAP certification tests interoperability for the many common EAP methods Name Extended EAP (Extensible Authentication Protocol) Introduced April 2005 Status Mandatory (for Enterprise products) Certifications EAP-TLS: 1,564 (May 2006) … Observations Certifies interoperability of: –EAP-TLS –EAP-TTLS/MSCHAPv2 –PEAPv0/EAP-MSCHAPv2 –PEAPv1/EAP-GTC –EAP-SIM Lessons for WFA & IEEE Users have diverse needs and will not be told they can only have a single solution Users sometimes want proprietary mechanisms

30 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 30 The Wi-Fi Protected Setup certification aims to make security easy to set up in the home Name Wi-Fi Protected Setup™ - PIN Wi-Fi Protected Setup™ - PBC Introduced January 2007 Status Optional Certifications PIN: 32 (May 2006) PBC: 22 (May 2006) Observations WFA developed a specification to make easier for home users to configure security Two variants are currently certified (PIN, Push Button) with NFC likely soon Relatively new certification and its success is still unclear Lessons for WFA & IEEE Developing good specifications or standards is hard! Enterprise & home markets have different needs

31 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 31 The success of the WMM certification of QoS is building after a slow (& maybe too early) start Name WMM (Wi-Fi Multimedia™) Introduced September 2004 (standard ratified Sept 05) Status Optional Certifications 379 (May 2006) Observations Based on WFA’s WMM spec, which is similar to a fraction of e (EDCA) WMM developed when it seemed unlikely 11e would be ratified soon WMM success has been slow but is now building because EDCA is needed in new apps Lessons for WFA & IEEE It’s really hard to pick what is needed and when

32 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 32 The WMM Power Save certification provides a platform for “next generation” applications like voice Name WMM (Wi-Fi Multimedia™) Power Save Introduced December 2005 (standard ratified Sept 05) Status Optional Certifications 41 (May 2006) Observations Based on WFA’s WMM specification, which is similar to APSD in e Success has been slow but it is believed need for WMM-PS will grow because it is an enabling technology for many “next generation” applications –eg voice Lessons for WFA & IEEE The promise of voice is coming but slowly

33 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 33 The CWG-RF certification represents the first significant WFA experiment in performance testing Name RF Performance Evaluation of Wi-Fi Mobile Converged Devices Introduced Sept 2006 Status WFA optional CTIA mandatory for –CDMA/Wi-Fi in April 07 –GSM/Wi-Fi soon! Certifications 1 (May 2006) Observations Joint certification with the CTIA First WFA experiment with performance testing Certifies the RF performance of mobile converged devices (but results are private to vendor) Limited impact or success so far but expected to ramp soon now that CTIA making it mandatory & number of labs increasing Lessons for WFA & IEEE None yet …

34 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 34 The 11h+d certification, representing a small part of h/d, is useful but not required for 5GHz operation Name h+d Introduced Early 2004 Status Optional –11h in 5GHz band –11d in 2.4GHz 7 5GHz bands Certifications 11h: 106 (May 2006) 11d: 119 (May 2006) Notes Based on very small subset of h and d Uses conformance testing Makes use of 5GHz band with radar requirements easier but it is not actually required Lessons for WFA & IEEE The market will use only the subset of amendments that it perceives to be useful –ie very little of h is actually tested as part of certification

35 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 35 The “lessons” highlight the contradicting forces we face together & a potential new direction Make the right features available to the market on time Standardisation by committee Start early Anticipate the market Produce “bloat-ware” Get it wrong and waste effort Standardisation by the market Start late Follow the market Act as “rubber stamp” Get it right but too late Goal The answer should be a compromise The IEEE & WFA can work together to satisfy market needs in a timely manner, eg 11i/WPA The IEEE & WFA need to avoid: –Working against each other, eg 11e/WMM –Ignoring each other, eg early WFA input into 11n One extremeOther extreme

36 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 36 The agenda is focused on open communications between the WFA & the IEEE G Who is the WFA? What, who & how What have the WFA done in the past? Lessons learnt What can the IEEE WG do to help? What are the WFA planning to do in the future? Plans & possibilities

37 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 37 The WFA has definite plans for new certifications, mostly related to the voice opportunity PHY/MAC Draft n Applications Voice Over Wi-Fi –Home & Small Office –Enterprise QoS WMM –Admission Control Wi-Fi Mobile Convergence Device class

38 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 38 The WFA will start the draft n certification in June 07 Name Draft n Planned June 2007 Status Optional Certifications Draft 80211n based on D2.0 Handheld and CE profile (2008?) Ratified n (2008?) –Hopefully backward compatible Observations The market has demanded a certification on baseline 11n well before 11n is ratified; both WFA & IEEE are late Press release issued today, with consumer white paper & test bed Lessons for WFA & IEEE The market will respond without waiting for the standards or certification processes

39 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 39 The planned WFA device class certification will support the needs of converged devices Name WMC – Device class Planned 2007? Status Optional Observations Defines three types of tests for converged devices when the cellular phone is active & when a cellular signal is present: –Association tests –Throughput tests –VoWi-Fi tests Verifies converged devices can handle Wi-Fi data/voice applications with acceptable performance during simultaneous cellular operation

40 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 40 The planned Voice – Home and Small Office certification will extend Wi-Fi testing into the realm of performance Name Voice – Home & Small Office Planned 2007? Status Optional Observations Uses existing WFA certifications tests as baseline, including WMM & WMM-PS Adds minimum performance tests to show operation possible with four voice streams: –Throughput –Packet Loss –Delay bound –Jitter

41 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 41 The planned Voice – Enterprise certification will extend Wi-Fi testing into the realm of performance Name Voice – Enterprise Planned 2008? Status Optional Observations Similar concepts to Voice – Home & Small Office Extended to handle requirements of the enterprise, particularly for low latency hand- off and measurement Will also includes tests for: –802.11r functionality –802.11k functionality –WMM-AC

42 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 42 The WMM-AC certification will extend the WMM certification to admission control Name WMM-Admission Control Planned March 2008 Status Optional Observations Based on WMM specification, although some efforts are being made to realign aspects with 11e

43 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 43 The WFA has less definite plans for additional certifications in the medium term Applications Video Security Extended EAP methods Management frame protection (based on w) Wi-Fi Protected Setup™ extensions Wi-Fi Mobile Convergence Handover RF Performance with Blue Tooth Power consumption Other Mesh (based on s)

44 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 44 The WFA has very vague plans for additional certifications in the long term Standards p (Vehicular W-Fi)? u (Interfacing with external networks)? v (Radio Resource Management)? y (3.6GHz PHY)? … Other Who knows?

45 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 45 ? Develop own specs Use specs Use other specs The likely & possible certifications highlight a variety of challenges facing the WFA Follow the market Lead the market Interoperability Performance Conformance Layer 1/2 only Upper layers too Partnership with others

46 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 46 The agenda is focused on open communications between the WFA & the IEEE G Who is the WFA? What, who & how What have the WFA done in the past? Lessons learnt What can the IEEE WG do to help? What are the WFA planning to do in the future? Plans & possibilities

47 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 47 VHT DLS QES VTS One view of suggests it is succeeding in supporting “everywhere for everyone” Start a 11d 11g 11h 11i 11e 11k 11b 11n 11p 11w 11j 11r 11s 11u 11y Delighted to be connected Delighted to be securely connected Demanding managed, reliable & secure connections anywhere with high performance for any application 11v 09 In development Scheduled Ratified

48 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 48 However, the objective evidence suggests the WG has not been so successful in recent times No amendments have been ratified since 2005 and only one is possible in 2007 The last “useful to customers” amendment was arguably ratified as far back as 2004 Development of recent amendments is taking too long; about twice as long as ratified amendments The increasing number of parallel amendments increases risks arising from complexity

49 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 49 No amendments have been ratified since 2005 and only one is possible in k?

50 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 50 The last “useful to customers” amendment was arguably ratified as far back as mid h (Sept 2003) Only tiny fraction used for spectrum manage. A building block for future amendments 11j (June 2004) Mostly not implemented A building block for future amendments 11e (Sept 2005) Mostly not implemented Arguably incomplete WMM just ramping Less useful 11g (June 2003) Wildly successful in the market place 11i (June 2004) Required for the market place to even exist Useful today

51 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 51 Development of recent amendments is taking too long; about twice as long as ratified amendments In development Approved

52 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 52 The risks associated with complexity are increasing along with the number of parallel amendments Note: excluding rollups and recommended practices, eg 11F, 11ma/mb, 11T

53 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 53 More subjective evidence also suggest some standards development issues for the industry “Hallway” comments suggests that at least people believe: standards are often “bloated” with unused or broken features standards reflect political compromise too often, and not the proven needs of the market standards look like “the house that Jack built”, making further development increasingly difficult are losing the simplicity that made them so successful in the first place standardisation process is too slow …

54 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 54 The traditional model of throwing standards & certifications “across the wall” no longer works “Feature bloat”“Differentiated features”“Minimal features” Standards group Vendors Industry association Supports industry- wide branding and communications Marketing Defines complex, feature-rich technical standards for PHY and MAC Technical Specifies subsets of IEEE standards Undertakes interoperability testing Technical Adds differentiating features based on standards, but often before standards Technical Sells and supports vendor’s wireless products Sales Markets vendor’s wireless products Marketing Traditional model places standards group too far from “market needs” resulting in slow development & bloated standards

55 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 55 The traditional model of throwing standards & certifications “over the wall” no longer works Vendors Industry association Standards group The current model “throw it over the wall” A better model? “work together continuously”

56 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 56 So what can the WG do to better meet market needs in a timely manner? Some suggestions can be added to those made in Nov 06 Internally focused options might include: –Consider smaller more focused amendments? –Develop less (big) amendments in parallel? –Change culture away from rules based back to consensus? Externally focused options might include –Only standardise proven technologies, with less “academia”? –Change direction (even midstream) based on industry feedback? –Find ways to support certification of stable elements of drafts? –Adopt what industry does as a matter of course? eg WMM/11e –Look for new standards development models? eg wrt VHT? The answer is up to the IEEE WG but will have an effect on the continuing market relevance of the standard Market needs?

57 doc.: IEEE /0764r0 Submission May 2007 Andrew Myles (Cisco)Slide 57 The WFA is willing to help in whatever way necessary because this is our industry too! The WFA want to use standards to meet market needs Allow us to evaluate market needs relative to technical features on an ongoing basis Consider changing course based on these markets evaluations Help us to provide certification of early drafts (perhaps by standardisation of subsets of features) to the market …
