My thought was the panellists get to speak for a few minutes on whatever they like,
the chair gets to ask a couple of questions to be handled by the panel as a body, and
we take a few questions & comments from the floor.
Copying Rolf because I asked him offline if he was interested in participating.
I don’t think we have to rush into this. If it looks like folks need time to prepare,
we can delay until a later meeting. I’d rather have something successful and well thought out
than early. This might also be a possible use for the “Interest Group” mechanism we have
in 802.11.

Adrian P STEPHENS

Hello Adrian,
I concur with Osama too. Thanks also for Jeorge in his preparation as well.
As for the panel, will you prefer, e.g.,
[1] A moderator asks a few questions and each panelist provides their view in turns verbally; or
[2] A moderator asks a few questions, each panelist presents a presentation slide deck for 5-10 minutes on their views on these/selected questions, and then the panel start discussion.
Regards,
Edward

I found Jeorge’s e.mail controversial enough to stir good discussion. I am not sure if 5G guys would agree that 5G is 95% WLAN.
Maybe Adrian can invite a couple of providers who attend the IEEE 802.11 meeting to provide 10-minute view on their visions of 5G. NTT is one candidate.

Osama.

Jeorge, Adrian,
We only have one other presentation on the WNG agenda, so we could spend a total of about 90 minutes on this topic; we could use Jeorge's presentation as an introduction and segue into a panel discussion from there. Seems like a reasonable thing to do as long as we have >2 people willing to participate in the panel, have a dialog and do audience Q&A.
Best regards,
Jim

Adrian, et al,
I think this is a very important topic that deserves the kind of discussion that you are proposing,
Here is the link to the February 17, 2015 NGMN 5G White Paper: https://mentor.ieee.org/802.11/dcn/15/11-15-0322-01-0reg-ngmn-5g-white-paper.docx
Here is a link to the Rev. 0 of the Power Point overview of same paper: https://mentor.ieee.org/802.11/dcn/15/11-15-0547-00-0wng-ngmn-5g-white-paper-overview.pptx
Based on the NGMN 5G White Paper and other references, I have the following initial thoughts:It appears that "5G" is shaping out to be 95% WLAN and 5% cellular technology (these proportions, of course, are subject to debate). However, I have the perception (right or wrong), that 5G as a "brand" is 99.99% market driven by cellular operators, and 0.01% by WLAN technology providers, including 802.11.
I also believe that the DoCoMo vision of 5G as presented at various forums, including at the Small Cells Expo in London last year, confirms above perception. The DoCoMo 5G vision shows a whole bunch of 802.11 "towers", ranging from 802.11ac to (what appear to be) 802.11ad, co-existing with cellular technology via LAA (license assisted access). DoCoMo's slide title on this was "Wi-Fi integration on 5G access networks." Which technology is used, DoCoMo shows, depends on what throughput is required at any given time at any given range and user mobility velocity. Bottom line: use the best available technology, and guess what, most of the time, the user is stationary when he/she requires the highest throughput.
In addition, while the 3GPP has publicly stated that they are addressing LAA with 802.11ac technology for the downlink (for example, our 3GPP guest in Atlanta in January) and would not publicly state a similar direction with 802.11ad or derivatives, again, the DoCoMo vision appears to infer that this will eventually happen as well.
Dual-technology Small Cells with Qualcomm chips are starting to pop out which have both 802.11ac and cellular, clearly an indication of a path into LAA 5G.
So my quick summary, again is:
- 5G" is 95% WLAN and 5% cellular technology.
- 5G as a "brand" is 99.99% market driven by cellular operators, and 0.01% by WLAN technology providers.
- Dual-technology (Wi-Fi + Cellular) Small Cells (from Pico to Femtocells) driven by the cellular network operators could conceivably take on the Wi-Fi market away from traditional Wi-Fi router suppliers, under a new marketing brand: "5G." What is the economic impact of this move to the end users like you and me? Today Wi-Fi is virtually free, but will it be free under the cellular operators 5G small cells umbrella?
Additional Questions:
1. Should the 802.11 play a more active role under the 5G umbrella? If so, how do we do that, both from the technology and marketing perspectives? I think this is the intend of Adrian's suggestion for a panel on this subject at the WNG SC.
2. Does the 802.11 have a liaison with the Small Cells Forum, who are driving small cells within the operators as a way of the future? See
http://www.smallcellforum.org/A request for comments on the NGMN 5G White Paper was sent out to about ten 802.11 volunteers. Here are a few of the most relevant comments:
"According to the white paper the 5G is supposed to accommodate devices that are very different in their characteristics, e.g. sensors with limited power and perhaps limited rate capabilities, to smart phone and other potentially high speed devices. It was mentioned that single RAN and multiple RANs are possible. Would 5G defines a single access method that fits all devices?"
"The Business Model on page 19 doesn’t include customer billing. In particular would the customer be billed for the use of the license-exempt spectrum in the same way as he/she is billed for the licensed spectrum?"
"There is no discussion on the coexistence of various technologies."
"On Page 95, for M2M, 802.11ah is also working for IoT/M2M use cases. In that sense, it is recommended that technologies for small packet transmissions in the technology building blocks (Annex D, R2) should mention the activities on the IEEE 802.11 (TGah and TGax?)."
"Also, in addition to the signaling overhead issue of the small packet transmissions, the energy efficiency of the device should be analyzed because it is a key requirement of IoT/M2M market."Thanks

Subject: Panel session for WNG on NGMN
Hello all,
Let me expand on something I spoke briefly about last night at the CAC call.
I was wondering if we could do a “panel session” on 5G in the WNG slot.
Questions that might be considered are:1. Is 802.11 relevant to 5G
2. Can 5G meet its goals without 802.11
3. Is 802.11 sufficiently influential in those behind 5G
The purpose would be to allow attendees to develop their understanding of the
relationship of 802.11 to 5G.
Let’s have an email thread about whether this makes sense.
Best Regards,
Adrian P STEPHENS
