<span style=" font-size:10pt;font-family:sans-serif">Dear All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">this is my proposed
text to be sent to SOIS-WIR.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Basically, it
is the agreed WG text apart from the final text included between </span><span style=" font-size:10pt;color:red;font-family:sans-serif">>>>
and in red color</span><span style=" font-size:10pt;font-family:sans-serif">
for those that get the colors in my email.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I decided to remove
the book color change from blue to green or orange since, as remarked by
the SLS AD, our justification: </span>
<br>
<br><span style=" font-size:10pt;color:blue;font-family:sans-serif">If
the SOIS-WIR wishes to publish this document, the RFM WG would suggest
a Green Book or, alternatively an Orange 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. The RFM WG does not
believe this standard has been met given the comments above and a general
lack of solid documented experimental evidence. </span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">could be countered
by the pending prototypes.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">The reason for
this major change comes from reading the CCSDS rules and the SOIS-WIR project.
In principle the BB is not published until the relevant indendent prototypes
are available so we may be able to make our point without creating too
much confrontation (agency reviews are normally done before the protoypes).</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Have a look at
it and let me have your comments by Nov 25 (it's just 5 lines.)</span>
<br>

<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Dear Kevin,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">thanks for the
provided material that the RFM WG has studied in detail in relations to
the comments and requests for changes provided on the previous version
of the book by the RFM WG.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I am pleased to
report that th RFM WG finds the disposition of the comments about frequency
bands in relation to SFCG Lunar Martian recommendations in line with RFM
WG requests.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Concerning the
protocols per say, the RFM WG would like to offer instead the following
comments:</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">1.
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 be put in a background or
introductory section.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">2.
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.
Page 2-2, item 2): “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>
<br><span style=" font-size:10pt;font-family:sans-serif">4.
Page 2-2, item 2): “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.
Page 2-2, item 2): “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. 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.
Page 2-2, item 2): “For additional technical
background see Wireless Network Communications Overview for Space Mission
Operations (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 the WG provide a reference that actually
applies the theory to a planetary application? </span>
<br><span style=" font-size:10pt;font-family:sans-serif">7.
Page 2-2, item 3): This point is more background
or introduction information and should not be in a summary section.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">8.
Page 2-3, item 4): This point is more background
or introduction information and should not be in a summary section.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">9.
Page 2-3, item 5): This item is also background
or introductory information.</span>
<br><span style=" font-size:10pt;font-family:sans-serif"> </span>
<br><span style=" font-size:10pt;font-family:sans-serif">The RFM WG general
comment is that this new section starting at page 2-1 does not address
the original three comments which are repeated below for reference:</span>
<br><span style=" font-size:10pt;font-family:sans-serif"> </span>
<br><span style=" font-size:10pt;font-family:sans-serif">1.
Although document has a lot of information of the
proposed standards, we don’t see requirements that are 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>
<br><span style=" font-size:10pt;font-family:sans-serif">2.
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>
<br><span style=" font-size:10pt;font-family:sans-serif">a.
How does the multipath effects of the lunar surface
affect the throughput of the links?</span>
<br><span style=" font-size:10pt;font-family:sans-serif">b.
Are there outages created by crater or surface shadowing?</span>
<br><span style=" font-size:10pt;font-family:sans-serif">c.
Is the multipath frequency selective or flat? How
does this affect the service quality?</span>
<br><span style=" font-size:10pt;font-family:sans-serif">3.
If there are supporting documents to the protocols
for Lunar applications, please list. The reference document list
does not have this. Only terrestrial applications are specified for 3GPP.</span>
<br><span style=" font-size:10pt;font-family:sans-serif"> </span>
<br><span style=" font-size:10pt;color:red;font-family:sans-serif">>>></span>
<br><span style=" font-size:10pt;color:red;font-family:sans-serif">The
RFM WG has no evidence that the material included in the book is sufficient
and appropriate for a recommended standard (blue book) until the activities
with the two independent prototpyes (one by NASA/Nokia and one by CSA/Star
Solutions as per </span><a href="https://cwe.ccsds.org/fm/Lists/Projects/DispFormDraft.aspx?ID=703&Source=http://cwe.ccsds.org/fm/Lists/Projects/AllOpenChartersWithDraftProjects.aspx"><span style=" font-size:10pt;color:red;font-family:sans-serif">https://cwe.ccsds.org/fm/Lists/Projects/DispFormDraft.aspx?ID=703&Source=http://cwe.ccsds.org/fm/Lists/Projects/AllOpenChartersWithDraftProjects.aspx</span></a><span style=" font-size:10pt;color:red;font-family:sans-serif">)
are completed and the results are assessed by the RFM WG.</span>
<br><span style=" font-size:10pt;color:red;font-family:sans-serif">As such,
noting that the BB cannot be published anyway before the two protypes have
been demonstrated, the RFM WG recommends to SOIS-WIR not to proceed with
the Agency Review of this book until the two prototypes are available to
close all the issues highlighted by the RFM WG, assuming that the test
plan for the prototypes will encompass all raised problems.</span>
<br><span style=" font-size:10pt;color:red;font-family:sans-serif">>>></span>
<br><span style=" font-size:10pt;font-family:sans-serif">As said before,
the RFM WG would be ready to help your group advance in this very interesting
area. Joint working group meetings could be foreseen after addition of
the support task in the RFM charter.</span>

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>
The WG did review your input and Dennis was about to contact you with our
findings/recommendations.</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">
