Argh, should have know gr would call me on that...
But seriously, is that your only argument? Where's your data? I should
have said: Also, note that the (portion of the) 2.4G band (used by
ricochet) is licensed spectrum.
Better?
I don't have the ricochet frequencies readily available, but I can dig
them up at home. However, it appears that the unlicensed portion of the
2.4G band is only ~85MHz. In that band, certain types of transmission
(DSSS and 'DSSS-like' techniques) are allowed at specified power
levels. That portion is used by unlicensed phones and networking gear.
The Metricom 2.4G band license was supposed to be auctioned along with
everything else when ricochet went under. I don't recall if Aerie
acquired it or not.
