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 wi=
th a
powerline PHY.
3) Presence information in large mesh networks. This presentation descri=

a protocol that provides upper layers with a means of communication with re=
mote
nodes, but no efficient means of knowing which nodes are reachable in the f=
irst
place. Accordingly, presence service should be implemented at Layer-2 becau=

WNG had 1 session at this meeting, with 3 presentations
- WMM/11e
PAR Considerations (11-07-0116r0). The presentation considers the need to transition I=
EEE
802.11e to WMM (Wi-Fi Multimedia) as it is felt that WMM has been adop=
ted
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 11-07-002=
9r1)
be established within IEEE 802.11, to harmonise these two specifications.<=
/o:p>
- Audio
Video Multicast Protocol (11-07-0034r0). The presenters want to support services such as IPT=
V.
It is known that IEEE 802.11e provides QoS=
for
AV connections, however, AC-VO and AC-VI ha=
ve
high collision probability because of the small contention window. AV
multicast protocol can't provide QoS becau=
se 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 ov=
er 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 present=
ers
are trying to narrow the scope of potential work in this area. Between
November 2006 and this meeting, the presenters hav=
e had
a couple of conference calls and it was dec=
ided
that it is now appropriate to give an update on what was discussed and
what conclusions have been arrived at.=
No=

2006, Dallas, Texas,
USA=
WNG had 1 session at this meeting:
There were 4 presentations:
- Multicast Issues Multimedia App=
lication:(
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 presenta=
tion
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 presen=
ts 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 <=
span
class=3Dspelle>transmissions.Again it refers to t=
he
limitations of the current IEEE 802.11 multicast scheme, especially wh=
en
considering power saving. It is felt that this is important for light
weight battery terminals (e.g. PDAs). Results are shown for various IE=
EE
802.11 power saving modes. The conclusion is that a new power conserva=
tion
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 oppo=
sed
to "combative" use. Following these strategies all the STAs =
in a
cell can win. This concept is different from multihop, where STAs are essentially rela=
ys
within a network. Co-operation can use a partner STAs within the netwo=
rk
and utilizes macro-diversity in the receiver as shown in slide 3 (i.e.
simultaneous reception of the same frame from diff=
erence
sources). The paper then goes onto to prese=
nt
various co-operative methods which have cur=
rently
being discussed within academia. These oper=
ate at both PHY and MAC layers. They would be very us=
eful
for in-home networks and provides considera=
ble
benefits for video distribution.
- : 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.

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 revie=
wed
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 =

niques
to solve and reduce the output matrix values.
- Multi-media challenges for IEEE 802.11 : 11-06-0892r1. The submission look=
s at
AV networks and also some of the requiremen=
ts 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 sys=
tem,
but unfortunately outdoor locations are completely different environme=
nts
and up to 40 channels may be required.

ation :
11-06-1021r1. Presentation about the motivation and objective behind t=
he
proposed audio visual study group. It is fe=
lt
that such extensions to IEEE 802.11 will allow it<=
/span>
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).

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 B=
it Rates : 11-06-0635r1r0=
. This
document proposes that the IEEE 802 - 2001 Overview and Architecture
(Wireless Delivery) error rate specification is impossible to meet. Th=
is
is essentially because you ca=
n 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 me=
sh
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/vi=
deo
(AV) streams. These devices all have stringent Qo=
S
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 numb=
er).
The use case is very similar to that presented in the previous
presentation, which shows the digital home of the future. The presenta=
tion
suggests that IEEE 802.11e can be used for =
the
channel access mechanism, but by using a random AIFSN, the channel acc=
ess
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 TG=
v
in March 2006. Initially WLAN had low congestion, and therefore high <=
span
class=3Dspelle>QoS. But this situation will change in the futur=
e.
However, channels will be limited, even with direct link (peer to peer)
IEEE 802.11n operation. The document discusses these issues. 3 straw p=
olls
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 80=
2.11
has mechanisms in place to support admissio=
ns
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 se=
t of
wireless devices which can boost aggregate throughput beyond what an
enhanced link protocol can.

WNG had 2 sessions at this meeting:
The first session had 4 presentations:
- 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), <=
span
class=3Dgrame>an European funded project under the IST 6=
th
framework program. It focuss=
ed
on the mobility architecture and the challenges and potential solutions
for fast handovers.
- Introduction to CIRCLE (Communications Infrastructu=
re
Restoration in the event of Catastrophic Loss of Equipment)
(11-06-0433r0). This presentation initiated a discussion of catastroph=
ic
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 presentation=
s:
- 802.11 and PLC (11-06-04=
74r0).
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. T=
he
discussion focused on trends, use-cases in HD vide=

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 improvem=
ents
to network performances. Thus, the classical col=
lision
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, whi=
ch
previously have not been implemented with a multipacket reception (MPR) model. The author proposed
applying recent information theoretic results in multiuser iterative decodi=
ng
to help improve IEEE 802.11 wireless LAN standards' performances. This meth=
od
also preserves the underlying physical layer's implementation.
4. 802.11 MAC extensions for high rate video.=
This
presentation identified a two-dimensional QoS a=
nd
dynamic priority, rate and FEC adaptation based on RRM. Initial results were
presented on the home networking scenarios, simulation of 802.11e, and a di=
rect
link selection mechanism.
