May 2008, Jacksonville, Florida, USA

WNG had 3 presentations in this meeting

1) Segregated Data Services in 802.11. This presentation is a revised version of an earlier presentation given at the Taipei meeting. It introduced the segregation of traffic between a mesh and fixed infrastructure. The author is invited to provide a more detailed presentation at the next meeting.

2) Faciliting Powerline Communication (PLC) PHYs. This presentation focused on an alternative to wireless communication - powerline communication (PLC). There exists several consumer and SOHO use cases where wireless communication cannot reach with sufficient bandwidth and it is impossible to pull new wiring. Powerline communication usefulness could be facilitated by combining an 802.11 MAC with a powerline PHY.

3) Presence information in large mesh networks. This presentation describes a protocol that provides upper layers with a means of communication with remote nodes, but no efficient means of knowing which nodes are reachable in the first place. Accordingly, presence service should be implemented at Layer-2 because it can make reactive routing protocols more efficient and does not break power-saving schemes at Layer-2.

March 2008, Orlando, Florida, USA

WNG had 3 presentations in this meeting

1) Mobility Concepts in 802.11. This presentation highlighted several fundamental topics related to mobility extension. The author is invited to provide a more detailed presentation at the next meeting.

2) WAVE Enhancement. This presentation focused on enhancements to V2V (vehicle to vehicle) and V2I (vehicle to Infrastructure) and why its important to consider the issues relevant to 802.11 for vehicular deployments.

3) Impact of Multi-hop MESH flows on WLANs. This presentation is a follow up from a presentation in 2007 and the author has done some simulations based on feedback from earlier meetings.

January 2007, London, UK

WNG had 1 session at this meeting, with 3 presentations

  • WMM/11e PAR Considerations (11-07-0116r0). The presentation considers the need to transition IEEE 802.11e to WMM (Wi-Fi Multimedia) as it is felt that WMM has been adopted in the market place and has aspects that do not interoperate with IEEE 802.11e. Following a short introduction the presentation requests, that a new Task Group (PAR and 5C proposal available in 11-07-0029r1) be established within IEEE 802.11, to harmonise these two specifications.
  • Audio Video Multicast Protocol (11-07-0034r0). The presenters want to support services such as IPTV. It is known that IEEE 802.11e provides QoS for AV connections, however, AC-VO and AC-VI have high collision probability because of the small contention window. AV multicast protocol can't provide QoS because the collided frames are lost and unfair channel access between AV multicast and AV unicast occurs. This presentation addresses some of these issues in more detail.
  • An update of Video over WLAN (11-07-0105r0). For over a year, there have been various presentations within WNG SC looking at the need to provide a higher level of QoS in particular for video transmission over IEEE 802.11. The presenters are trying to narrow the scope of potential work in this area. Between November 2006 and this meeting, the presenters have had a couple of conference calls and it was decided that it is now appropriate to give an update on what was discussed and what conclusions have been arrived at.

November 2006, Dallas, Texas, USA

WNG had 1 session at this meeting:

There were 4 presentations:

  • Multicast Issues Multimedia Application:( 11-06-1687r0). The basic premise is that current multicast support in IEEE 802.11 is not suitable for high speed video Multimedia transmission. This submission builds on an earlier presentation made in WNG in July 2006. It would be useful to allow multicast transmission for the home environment and possibly the enterprise environment. It talks about the current unreliable multicast mechanism, which does not use an acknowledgement mechanism. The submission presents 4 separate issues which need to be addressed. A strawpoll was taken to ascertain if there is sufficient interest to start a new Study Group.
  • Power Saving Limitation for Multicast Applications (11-06-1747r0) . This submission presents an overview of the power management scheme in IEEE 802.11 standards and discusses its limitation with regard to the multicast cases. This would be typically useful to live TV and Video on Demand transmissions.Again it refers to the limitations of the current IEEE 802.11 multicast scheme, especially when considering power saving. It is felt that this is important for light weight battery terminals (e.g. PDAs). Results are shown for various IEEE 802.11 power saving modes. The conclusion is that a new power conservation system should be designed for STAs.
  • Cooperative Cross-Layer Communication (11-06-1767r0). This submission introduces various PHY layer cooperative communication concepts to the IEEE 802.11 community. Significant performance (throughput, range, reliability, etc.) enhancements are possible by the "cooperative" use of STAs in an IEEE 802.11 network, as opposed to "combative" use. Following these strategies all the STAs in a cell can win. This concept is different from multihop, where STAs are essentially relays within a network. Co-operation can use a partner STAs within the network and utilizes macro-diversity in the receiver as shown in slide 3 (i.e. simultaneous reception of the same frame from difference sources). The paper then goes onto to present various co-operative methods which have currently being discussed within academia. These operate at both PHY and MAC layers. They would be very useful for in-home networks and provides considerable benefits for video distribution.
  • CoopMAC: A cooperative MAC compliant with IEEE 802.11 (11-06-1642r0): This submission also dealt with cooperation between the MAC and PHY layers. It presents some of the motivations of co-operation. Essentially co-operation is useful as the wireless link is unreliable. It builds on the previous submission and shows how receiver combining can work in practice. In addition it has some performance results for IEEE 802.11g with and without co-operation. The results also show channel access delay and energy efficient measurements when using this system. A demo was constructed with 4 laptops, utilizing 2 helps (partners) and results were presented. The conclusion is that co-operation in the MAC layer, significantly improves the performance of the system.

September 2006, Melbourne, Victoria, Australia

WNG had 1 sessions at this meeting:

There were 3 presentations:

802-11a-in-outdoor-mobile-environments(06/1339r0). This presentation demonstrated the IEEE 802.11a waveform can be used in outdoor, mobile environments without modification. This is achieved with receive side PHY processing improvements only. The channel experienced under outdoor, mobile conditions is reviewed and a baseband receive processor is presented that can cope with these conditions. This was followed by results from a recent field trial incorporating such a receiver. A video was also shown.

Extensions to DLS (06/1478r0) . This presentation identified few short comings in current DLS scheme defined as part of 802.11-REVma/D8.0 draft. It provided the rationale for examining DLS operation with non 802.11e APs and also power saving extensions to DLS. The presentation ended with a motion to form a Study Group in order to examine DLS operation with non 802.11e APs and to examine power saving extensions to DLS with the intent to create a PAR and five criteria to form a new task group.

Traffic-aware(06/0912r0). This presentation provided the rationale for traffic aware mechanism in WLAN and mesh environments.The benefits of traffic aware mechanisms can help alleviate traffic congestion in WLAN mesh. The benefits of load balancing and QoS guarantee were also explained.

July 2006, San Diego, California, USA

WNG had 2 sessions at this meeting:

There were 5 presentations:

  • 802.64 amendments to support CE (Consumer Electronic) Applications: Technical Requirements 11-06-0898r2. This document discusses consumer electronic (CE) applications and describes the technical requirements that should be met to provide high quality audio and video contents over IEEE 802.11. It is an revised presentation from 11-06-0655r0, presented in May 2006. There is a trend for more and more CE devices which now support wireless connectivity (e.g. home theatres, game consoles, Digital TV, Set Top Box). Document goes on to discuss many WLAN CE applications and discusses the adoption of DRM.
  • Layer 3 based MESH networking : 11-06-0916r1. Work also related to IETF activities (e.g. MANET, MASE) and they have several internet drafts already. This submission presents the work of various Japanese universities and groups, within the project "next generation ad hoc network base technologies". They have developed a test bed demonstrator across the university with more than 50 nodes.
  • MIMO-OFDM Beamforming : 11-06-0979r0. Detailed submission looking at a beamforming technique, showing mathematical techniques to solve and reduce the output matrix values.
  • Multi-media challenges for IEEE 802.11 : 11-06-0892r1. The submission looks at AV networks and also some of the requirements in the TV production studio, with typically 6-12 High Definition cameras. It must be remembered that a camera control channel is also required. TV studios are quite attractive for MIMO system, but unfortunately outdoor locations are completely different environments and up to 40 channels may be required.
  • WLAN for next generation AV : Motion for SG Creation : 11-06-1021r1. Presentation about the motivation and objective behind the proposed audio visual study group. It is felt that such extensions to IEEE 802.11 will allow it to play a major role in the entertainment industry. The ITU has just established a group looking at home networking, examining all wired solutions (but not wireless).

May 2006, Jacksonville, Florida, USA

WNG had 2 sessions at this meeting:

The first session had 4 presentations and the second session had 2 presentations:

  • IEEE 802 - 2001 Overview and Architecture General Bit Rates : 11-06-0635r1r0. This document proposes that the IEEE 802 - 2001 Overview and Architecture (Wireless Delivery) error rate specification is impossible to meet. This is essentially because you can not control the packet error rate or the latency of the system. There are so many parameters than you cannot control, e.g. CRC checksums, PLCP checksums etc. This is further complicated within a mesh architecture (e.g. IEEE 802.11s).
  • Use Cases of WLAN for Audio/Video Streams : 11-06-0655r0. This presentation introduces typical consumer electronic devices which could use WLANs (IEEE 802.11n) in the future (e.g. Digital TV, Home Theatres, Portable Multimedia Players - PMP), which typically use high data rate audio/video (AV) streams. These devices all have stringent QoS requirements.
  • MAC performance improvement using random AIFSN: 11-06-0713r1. This presentation looks at ways to alleviate contention within the home environment. AIFSN (Arbitration inter frame space number). The use case is very similar to that presented in the previous presentation, which shows the digital home of the future. The presentation suggests that IEEE 802.11e can be used for the channel access mechanism, but by using a random AIFSN, the channel access mechanism can be improved for multiple stream operation.
  • Multi-channel Direct Link Protocol for HD video: 11-06-0691r0. This presentation is an updated presentation from TGv in March 2006. Initially WLAN had low congestion, and therefore high QoS. But this situation will change in the future. However, channels will be limited, even with direct link (peer to peer) IEEE 802.11n operation. The document discusses these issues. 3 straw polls were taken.
  • Liaison-request-from-tia-tr41-4: 11-06-0720r1. This presentation is a summary of the liaison request from TIA TR-41.4 contained in IEEE 802.11-06/0557r0. It seeks information on whether 802.11 has mechanisms in place to support admissions control and prioritization requirements necessary for emergency calls from VoWLAN phones.
  • Proposed-multi-purpose-802-11-mac-extensions: 11-06-0632r1. This presentation described a possible extension of the 802.11 MAC protocol to allow parallel use of multiple channels by a set of wireless devices which can boost aggregate throughput beyond what an enhanced link protocol can.

  • 802.21 Liaison (11-06-0374r0). This presentation initiated a discussion on the liaison received from 802.21.
  • A presentation of the OBAN concept: An IST Project under EC's 6th framework (11-06-0353r0): This presentation introduces the concept of OBAN (Open Broadband Access Network), an European funded project under the IST 6th framework program. It focussed on the mobility architecture and the challenges and potential solutions for fast handovers.
  • Introduction to CIRCLE (Communications Infrastructure Restoration in the event of Catastrophic Loss of Equipment) (11-06-0433r0). This presentation initiated a discussion of catastrophic loss of communications infrastructure and highlighted the need for a standards approach to providing rapid recovery.
  • 802.11 MAC Extensions for Increasing Aggregate WLAN Throughput (11-06-0408r0). This presentation described a MAC protocol that allows parallel use of multiple channels which can boost WLAN aggregate throughput beyond what a link protocol can.

The second session (held as part of mid-week plenary) had 3 presentations:

  • 802.11 and PLC (11-06-0474r0). This presentation IEEE 802.11 technologies are relevant to Power Line Communications (PLC). It introduced IEEE PLC standardization effort (P1901) and offered some ideas of where partnerships can be established
  • Update on HD Video over WLAN (11-06-0360r0). This presentation provided a summary of activities on HD video over WLAN. The discussion focused on trends, use-cases in HD video, and relevant MAC enhancements with respect to these cases. The scope of a possible amendment to 802.11 was also presented.
  • More "what is 802.11u?" (11-06-0375r0). This presentation provided a deeper understanding of the scope of 802.11u. It provided an overview of the current status and process of 802.11u within the IEEE 802.11 standardization activities.

  • Ambient Project Update
  • OBAN (European IST Project)

November 2005, Vancouver, British Columbia, Canada

WNG had 2 main topics for discussion this meeting:

  • Opportunities and use of IEEE 802.11 for short range communications in Space (11-05-1132r0). This paper introduced opportunities for he exploitation of IEEE 802.11 within spacecraft and short range communications between spacecraft.
  • Video transmission update (11-05-1164r0). This paper gave a brief update to the video tranmission presentation given in the previous September meeting.

January 2006 Goals

  • Video transmission
  • OBAN (European IST Project)

September 2005, Garden Grove, California, USA

WNG had 4 main topics for discussion during the meeting:

1. IEEE 802.1AM PAR issues. WNG continued the discussion from the last meeting in July. Data brought into the group were discussed and considered very valid as part of a living document.

2. Update on FMCA. This presentation provided an overview of the FMCA. There is general interest from FMCA to foster good working relationship with IEEE 802.11.

3. Improving IEEE 802.11 Performance with Cross-Layer Design and Multipacket Reception via Multiuser Iterative Decoding. Receivers today have the ability to decode more than one packets from multiple users. Such a physical layer can deliver significant improvements to network performances. Thus, the classical collision model is no longer realistic and a cross-layer approach should be employed when designing multiple access protocols. This is especially the case for CSMA communications, which previously have not been implemented with a multipacket reception (MPR) model. The author proposed applying recent information theoretic results in multiuser iterative decoding to help improve IEEE 802.11 wireless LAN standards' performances. This method also preserves the underlying physical layer's implementation.

4. 802.11 MAC extensions for high rate video. This presentation identified a two-dimensional QoS and dynamic priority, rate and FEC adaptation based on RRM. Initial results were presented on the home networking scenarios, simulation of 802.11e, and a direct link selection mechanism.
