    "content": "All of this hoopla about S band in the AMSAT bulletin board, which \nthankfully is blocked to me because comcast has chosen to blackball \namsat.org (oh drat,  the block just got removed ;-)  )  caused me to do \nsome talking, searching,  thinking.  We are definitely NOT at the end of \nthis story.\n\nI believe the Netherlands has lost 2400-2540.   I am investigating with \nsome help how universal this is.   What I believe we are seeing is  that \nlike here,  the licensed operators are supposed to be protected but what \nactually happens is that when the licensed operators interfere severely \nwith the 802.11 use,  the amateurs are summarily dismissed.\n\nIt is my opinion that we got bloody lazy.  We took the ITU/IARU tables \nas found on the web and took them as gospel.   We need to understand the \nactual reality as found on the ground.   If we cede L band as an uplink, \nand we see a definite trend towards loss of 2400-2540 because of 802.11 \nacross Europe,  we are close to being between a rock and a hard place.\n\nThanks to Lee,  a study that was pointed out called ARIA.  This,  \ncommissioned by Paul Rinaldo at the League was EXACTLY what we are \nafter.   It is a study of the rise in noise floor at 2400 due to \n802.11.  Paul is a) helping me get the results and b) attending our \nsymposium and giving a talk on frequencies.\n\nRick and I spent an hour in discussions with a very high ranking general \nofficer at the Pentagon in a position to have an opinion worth listening \nto.  His opinion is that our band at L band is NOT in danger from \nGalileo.  I will not go into greater detail here and I will never put \nhis remarks in a public record.  But suffice it to say,  his remarks \nhave indeed caused me to go investigate this. \n\nWe did our TECHNICAL job in San Diego.  We have NOT done our regulatory \njob and our political job and it has caused many to write me in private \nabout existing situations.  I am afraid we are about to be made to look \nas if we are knuckling under to pressure and it will have nothing to do \nwith the pressure.  It will have everything to do with this story \ngetting out before we were ready to tell and had done all of our home \nwork.    If the serious impact of 802.11 resulting in loss of 2400 MHz  \nuplink privileges in region 1 and 2 and 3 can be substantiated, then \nthat is a fait d'accompli we must take into account.  The loss of \nprivilege, in every case I know of,  results from BLOODY ATV users \nblocking 802.11 users.  If we transmit and block,  we can cause the same \nkind of problem.    We need to understand how widespread this phenomenon \nis.  We now can document it has happened in LU.  I am given to \nunderstand by a European who should know that it is true also in the \nNetherlands.   We must find out how widespread.\n\nGiven loss of 2400 as a fact (should we find this widespread and \ngrowing),  I would risk using L band and 3400 instead rather than lose \nthe ability to use our satellite altogether within a very short period \nfollowing launch.   Should we find this to be necessary,  then we have a \ntough job to decide how, or whether to do  23cm, 9cm,  or both and if we \ndo both,  can we put credible antennas on the spacecraft.\n\nI believe Rinaldo is coming to tell us the cold hard facts of life.  Be \nprepared to listen.  I am also going to ask questions in the amsat-bb to \ntry to elicit first hand knowledge of loss of this band from lurkers there.\n\nBob\nN4HY\n\n\n-- \nAMSAT VP Engineering.
