the SOIS-WIR plenary, about the results of the last SFCG meeting in Australia (july 2022), and in particular the updates regarding wireless for the new SFCG recommandation about lunar frequencies:
<b>SFCG REC 32-2R4</b>, which has been approved, with the following lunar Wireless frequency bands, which therefore now apply to our 883 Blue Book. The good news is that new SFCG lunar wireless band has been added, and one extended:</span></p>

<p class="x_MsoNormal"><span lang="EN-US" style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">Another remark also FYI: Some colleagues pushe for a request to extend the SFCG “3GPP 2 GHz” band down to 2.500 GHz instead of 2.5035 GHz, but
SFCG REC 32-2R4 has kept the 3.5 MHz guard band between PNT (2483.5-2500 MHz) and Wireless (from 2.5035 GHz up to now 2.655 GHz). Now, CNES computations
<b>clearly demonstrates</b> that <b>PNT would have harmfull interferences if Wireless would go down to 2.5000 GHz</b> instead of 2.5035 GHz. In between, NASA LUNANET interface specification V3 published on internet mentioned PNT as a baseline in 2483.5-2500
MHz band. Moreover, the ESA baseline for PNT of MOONLIGHT is in 2483.5-2500 MHz too.
<i>To be noted in addition: NASA LUNANET V3 <b>is respecting SFCG</b> as shown by the figure bellow extracted from the specification:</i></span></p>

<p class="x_MsoNormal"><i><span lang="EN-US" style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">Also to be noted: there are not any frequencies bellow 2 GHz in the Shielded Zone of the Moon, in the the LUNANET interface specification
V3, NASA committing to protect Radio Astronomy in the Shielded Zone of the Moon; same thing for ESA’s MOONLIGHT baseline. Pushing downing to 2.5000 GHz, and therefore destabilizing PNT, would have actually as one of the consequences a re-highlighting of the
multilevel debate related to protection of RA in the SZM. </span></i></p>

<p class="x_MsoNormal"><span lang="EN-US" style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">To avoid all this, CNES kindly encourage the teams pushing for a 2.5000 GHz wireless limit instead of 2.5035 GHz to study a pragmatic lunar 3GPP
5G wireless solution in 2.5035-2.6550 GHz, even if one channel (even wide) would be “lost”, by optimizing as a maximum the different possible spectral configurations respecting SFCG and selecting accordingly hardware/software vendors. If such a pragmatic solution,
taking into account the need for a not interfered PNT, would be <b>really</b> impossible to be kindly decided, CNES kindly suggest to go directly to the SFCG 3.5-3.8 GHz lunar wireless band (for instance) for operational applications.
