Perhaps with all the "noise" (pun intended) here recently about
unlicensed transmitters on 2.4 GHz... the following line from the article:
"For a given TX e.i.r.p., signal strength received at Earth depends only
on the mechanical size of the RX antenna; frequency is irrelevant .
Noise level however is not, and S-band (2.4 GHz) is a sensible downlink
choice because very low noise performance is robustly obtainable "off
Is more controversial than it once was? :-)
Or maybe not. Depends on who's arguments one liked during the recent
2.4 GHz debate on the mailing list.
The above comments notwithstanding, nice article James. Thanks for
sharing the link. I learned something from reading it, and that's
always a Good Thing.
