<br><span style=" font-size:10pt;font-family:sans-serif">Dear All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I have received
the attached comments by Wai. I assume that the comments raised by Dennis,
Jean-Luc and me in cooperation with SFCG Lunar Martian Spectrum Group chairperson
are addressed so the only remaining items are those identified by Wai.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I would like to
know if:</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">1) You endorse
Wai's comments</span>
<br><span style=" font-size:10pt;font-family:sans-serif">2) You agree that
the book should be an orange book</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Please reply to
these two questions by <b>Nov 22</b>.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Note that in their
response, SOIS-WIR are of the opinion that any remaining comments shall
be addressed during agency review. However, given the time it takes to
start such process, I think we can still interact.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">The problem is
that SOIS and SOIS-WIR are not going to like these suggestions. Additionally,
SOIS AD is from NASA (GSFC) and SOIS-WIR chairman is from University of
Colorado while I am ESA as well as the SLS AD.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">If the WG agrees
with items 1 and 2, I would suggest SOIS AD to get in touch with Wai as
the RFM WG liaison being both at GSFC.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Looking forward
to your views,</span>

</span><span style=" font-size:11pt;font-family:Calibri">Overall
observation to this new passage in the executive summary: Most of
the items listed are general background material and not specific to the
application of the protocol to a planetary or lunar surface. It’s
odd that this information is contained in the executive summary section
which is supposed to be summary of the entire document. We will suggest
below items that should put in a background or introductory section.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">2.
</span><span style=" font-size:11pt;font-family:Calibri">Page
2-2, item 1): This point is more background information and should
be in an introduction.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">3.
</span><span style=" font-size:11pt;font-family:Calibri">Page
2-2, item 2): “</span><span style=" font-size:12pt;font-family:Calibri">Channel
models depend on environment and deployment architecture (see [36], [D23],
[D24], [D25]).” Again while this statement is true, it is very general
and more background information that should be in an introduction section,
not a summary. </span><span style=" font-size:11pt;font-family:Calibri">
</span>
<br><span style=" font-size:10pt;font-family:sans-serif">4.
</span><span style=" font-size:11pt;font-family:Calibri">Page
2-2, item 2): </span><span style=" font-size:12pt;font-family:Calibri">“LTE
frame structure and timing inter-symbol interference (ISI) protection scales
to multipath environments compatible with ~100 km link distances in mountainous
terrains on Earth and will easily address most reasonable planetary, lunar,
and other complex surface topography deployments.” Where is the
supporting documentation to this assertion?</span>
<br><span style=" font-size:10pt;font-family:sans-serif">5.
</span><span style=" font-size:11pt;font-family:Calibri">Page
2-2, item 2): “</span><span style=" font-size:12pt;font-family:Calibri">Delay
spread significantly below 1/15 ms has no impact on LTE symbol decoding.
This supports a path-spread of 10 km for received multipath components.
Channel models are studied in depth in IEEE, 3GPP, and ITU processes, easily
supporting the relatively small networks envisioned for spaceflight networks.”
Delay spread is a function of the channel, and RF frequency. If you
have a Lunar channel with reflection coefficients, carrier frequencies
and Doppler that are different from the terrestrial coefficients, then
that impacts the delay and Doppler spread which could make the total time
spread be much longer and this would impact the architecture of the network.
A detailed study of the Lunar or planetary surface is required to
make a detailed multipath model in order to make a good protocol.</span><span style=" font-size:11pt;font-family:Calibri">
We don’t see a reference or detailed study of the Lunar surface.
The closest reference is [D25], however this article deals with intra-crater
communications which is not likely to be a location for a lunar base.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">6.
</span><span style=" font-size:11pt;font-family:Calibri">Page
2-2, item 2): “</span><span style=" font-size:12pt;font-family:Calibri">For
additional technical background see <i>Wireless Network Communications
Overview for Space Mission Operations </i>(reference [D1]).” This
reference gives some fundamental description of multipath but it doesn’t
apply the information to a proposed Lunar or planetary network. Can you
provide a reference that actually applies the theory to a planetary application?

</span><span style=" font-size:12pt;font-family:Calibri">Although
document has a lot of information of the proposed standards, we don’t
see requirements that specific to Lunar environment, i.e. recommendation
for locating base stations and what is the density of base stations for
a required communications utilization.</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:10pt;font-family:sans-serif">2.
</span><span style=" font-size:12pt;font-family:Calibri">The
channel model is not referenced or specified in the document. We
would like to see a characterization of the RF environment so that the
protocols are justified. The protocols are designed for an Earth
like environment so some justification of why this will work on the Lunar
surface in necessary. </span></p>

<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri">As
a suggestion, if the SOIS-WIR wishes to publish this document, I would
suggest an Orange Book or as others have suggested a Green Book. A
Blue Book has to have strong simulation and/or analytical results to support
a CCSDS protocol. And results must be confirmed by two agencies. I
don’t believe this standard has been met given the comments above and
a general lack of solid documented experimental evidence. </span></p>

The RFM WG works with papers submitted two weeks in advance of the meeting
like other SLS groups. In light of the remote meeting for Fall 2020, we
did documents review by correspondence. The agenda does not entail a physical
mtg or videoconf, but just that we work on these issues.</span><span style=" font-size:12pt;font-family:Roman">

</span><span style=" font-size:10pt;font-family:Arial"><br>
<br>
So please refrain from sending us another version. Have first a look at
our recommendations and let us know what you think and what you could do
about them. We can still iterate our recommendations with your group, though.
If you are willing to take on board our requests, we can give you a few
weeks to carry it out.</span><span style=" font-size:12pt;font-family:Roman">
