[SOIS-WIR] One question on Nokia+Axiom frequency plans, and news from SFCG

[Issler Jean-Luc]

Dear Kevin, dear all,

I hope that you have a good summer so far!

*May I kindly ask if you or any member of SOIS-WIR WG could share the frequency band thought about by AXIOM and NOKIA for the 4G/LTE device of the AXIOM space suit mentioned in the link herebelow ?

https://www.nokia.com/about-us/news/releases/2024/08/21/nokia-and-axiom-space-partner-to-enable-high-speed-cellular-network-capabilities-in-next-gen-lunar-spacesuits/

(Hoping that AXIOM and NOKIA were wise enough to not have choosen Band-3 in the 1.7/1.8 GHz range, in order to have the suit equiped with devices above 2 GHz to be compatible with operations in the Shielded Zone of the Moon ! and also in order to respect our CCSDS 883 high data rate wireless proximity network standard )

*Also, SFCG-43 meeting in Bangalore decided last june to keep the SFCG lunar freqs REC (32-2R5; attached) as is for the time beeing, with now a consensus to keep the 3.5 MHz guard bands within the PNT band (mandatory to contribute to protect PNT efficiently). A consensus also occur for a public provisional recommendation on protection of Lunar S-band PNT, proposing a PFD limit in 2483.5-2500 MHz, to be respected by each lunar surface wireless system. This prov REC will be reviewed by next SFCG meeting, before to become a firm REC. CNES recommends the wireless devices implementers to take into account from now this Prov SFCG REC 43-1 (attached, and available in the SFCG web site: https://www.sfcgonline.org/Resources/Recommendations/default.aspx)

Have a nice day; Very best regards

Jean-Luc
