<DIV>Dear colleagues,</DIV>
<DIV> </DIV>
<DIV>Exactly, the definition of "proximity" is crucial for reasoning about
the wireless interconnections.</DIV>
<DIV> </DIV>
<DIV>And for me it has twofold point of view to the proximity: </DIV>
<DIV>1) from the point of view of applications; the discussion looks to go
mainly this way; </DIV>
<DIV>2) from the point of view of the technology.</DIV>
<DIV>As the CCSDS more adapt existing technologies than developing original
ones, the second point of view is important also when we discuss a range of
wireless technology.</DIV>
<DIV>For instance, for me the WiFi area for high-rate links or ZigBee for
low-rate define what is proximate and what is not. And a a rover traversing
several kilometers is definitely out of the range of this proximity.</DIV>
<DIV>WiFi/ZigBee area is quite enough for most onboard networking and to
overload onboard networking with technologies for 10 km doesn’t look
reasonable.</DIV>
<DIV>May be we need to define a proximity scale keeping in mind both
applications and available technology in its definition. </DIV>
<DIV> </DIV>
<DIV>Kind regards,</DIV>
<DIV> </DIV>
<DIV>Yuriy </DIV>

<DIV style="COLOR: rgb(0,0,0)">Thank you very much for your assistance in this
regard. The CESG clarification is timely and needed.</DIV>
<DIV style="COLOR: rgb(0,0,0)"> </DIV>
<DIV style="COLOR: rgb(0,0,0)">I have one observation which might become
relevant. Regarding the agreement for SOIS that:</DIV>

<DIV> <FONT class=Apple-style-span color=#ff0000>"SOIS
Responsibilities include: A) networked multi-point links utilising commercial
wireless network technologies for Communications onboard a space vehicle or
habitat and/or surface links within the proximity of that vehicle or
habitat"</FONT></DIV>
<DIV style="COLOR: rgb(0,0,0)"> </DIV>
<DIV style="COLOR: rgb(0,0,0)">There may be some debate over the exact
definition of "proximity", e.g., how far from a planetary wireless
infrastructure point. I'm thinking of the "golden scenario" of a rover
traversing several kilometers from a planetary surface infrastructure
point. I think (stating my view, not committing anyone else) that
planetary surface communication networks and infrastructure (e.g., surface
communications networks) are the domain of SOIS and anything space-to-ground is
SLS.</DIV>
<DIV style="COLOR: rgb(0,0,0)"> </DIV>
<DIV style="COLOR: rgb(0,0,0)">The argument that I would like to avoid is:
"Well, the rover is X km from the habitat so the communications link is the
responsibility of SLS, even though the communications are all over the ground
network." </DIV>
<DIV style="COLOR: rgb(0,0,0)"> </DIV>
<DIV style="COLOR: rgb(0,0,0)">I'm probably being somewhat anal, but we've gone
round-and-round with Jean-Luc Gerner in this regard previously. I guess we
can cross this bridge if/when we come to it.</DIV>
