to 883, and more broadly, for some future new bleu or green book(s) to be issued by Wireless WG. That is why this informal E-mail bellow was adressed to SOIS-Wireless WG only, and why I did not sent the 883 version submited to RFM to our WG, since it is not
my responsibility to do it.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">As Martin and I formally wrote to our WG, we considered the consensus to have been broken, and I simply informally wanted
to inform the WG that it is still the case (broken consensus) for me (unless comments received from RFM are integrated in 883). When stating about the broken consensus, Martin and I wrote that it is now at CESG level, I can therefore only agree with your statement
bellow that “it is a CESG level” (<i>but as mentioned you Kevin brought 883 also at SLS/RFM level, and I thought that minimum informal technical exchanges of technical facts between RFM and Wireless group members should have been be possible ?</i>). The specificity
here is also that several major paragraphs related to frequencies has been removed (in addition to more than 150 frequency references kept in the 883 main text), protection of Radio Astronomy in the Shielded Zone of the Moon and protection of non-wireless
SFCG lunar bands (including a very important one having a link with RA in the SZM). Theses removals has been made to the point of breaking the consensus that you declared, and to make uneffective and not real the declared disposition of most of the CNES RIDS
<i>(Normaly, PIDS proposed at CESG level by a participant/adviser involved in the Agency Review do not break consensus that much</i>). I therefore just wanted to informally make the status of the consensus (still lost) clear to our WG,

The 3GPP 4G 2.5 GHZ lunar and martian bands are therefore 2503.5-2620.0 MHz. SFCG confirmed also the Wifi 2.4 GHz lunar and martian bands: 2400.0-2480.0 MHz, that is not any channel, even partly spectraly speaking, above 2480.0 MHz. CNES hopes that the published 883 version will be clear in fully respecting these SFCG bands and in fully protecting the 2483.5-2500 MHz SFCG band. We know that there is not any CCSDS written rules, or even clear usage, precluding 883 to be unambiguous on this. Moreover, without this few frequency references allowing to re-create the consensus, the 883 version submited to RFM contains more than 150 frequency references in MHz or GHz ! SFCG also did not introduced new wireless bands which could threaten Radio Astronomy in the Shielded Zone of the Moon.</span><span lang="EN-US"><o:p></o:p></span></pre>
