[time-nuts] LightSquared asks GPS makers and users to pay for filters

I do not want to minimize the threat posed to GPS by Lightsquared 
("LS"), but the post below (i) ignores the last 3 months of debate on 
the subject and dozens of messages on this list, (ii) mis-states the 
case against LightSquared, and (iii) ignores the FCC's leading role 
in the fiasco.

LS did nothing nefarious.  The FCC established the basis for an 
"ancillary terrestrial component" ("ATC") to satellite services that 
uses terrestrial base stations on satellite frequencies to supplement 
satellite networks.  The first commercial application of ATC was to 
the satellite radio services ("SDARS").  There was a hue and cry from 
adjacent WCS licensees, and several FCC proceedings to resolve the 
issues, which are still under attack.

The FCC, on its own motion and with the blessing of the 
Administration, has decided that the US desperately needs 500 MHz 
more of wireless broadband spectrum or we will never recover from the 
recession.  Personally, I believe it is mistaken to think that 
enabling multi-player gamers and video watchers to squander vast 
amounts of wireless bandwidth will rejuvenate the economy -- but 
then, it was not my decision.  As a result of this muddled mindset, 
the FCC has been looking at every possibility to repurpose 
"underutilized" spectrum for wireless broadband.

One of the FCC's ideas -- and make no mistake, it was the FCC's idea, 
not something driven by political connections and campaign 
contributions -- is to greatly expand terrestrial broadband 
operations in the mobile satellite service ("MSS") bands.  No one can 
reasonably argue that the MSS bands are not "underutilized" -- as I 
remarked before, you can see the tumbleweeds blowing through.

Currently, expanded terrestrial use of the MSS bands requires a 
waiver of the "ancillary" part of the ATC rules.  However, the FCC 
has already begun the process of re-allocating the MSS bands to allow 
purely terrestrial uses on a co-primary basis.  When that 
re-allocation process is complete, the band will be fully open to 
terrestrial uses and no waiver will be necessary.  So, the LS issue 
is just the tiniest tip of an immense iceberg.  And again, that is 
ALL the FCC's doing.  It has nothing to do with graft, corruption, 
political connections, or campaign contributions.  Just bad decisions 
made in a time of unnecessary panic by the FCC.

LS has simply played by the rules the FCC set out.  It acquired huge 
chunks of MSS spectrum (for which it paid), and has applied to the 
FCC for the waivers necessary to use the spectrum terrestrially but 
not necessarily in connection with satellite service.  The FCC 
granted the waivers, subject to the outcome of technical tests 
demonstrating that such use would not interfere with other spectrum 
users (primarily, GPS users).  A committee was convened to test and 
report.  The report was due on June 15, and from what has been 
leaked, it documents serious and widespread interference to GPS 
systems.  LS sought (and was granted) an extension until July 1 to 
submit the report.  Last week, LS announced that it intended to 
launch its service on spectrum lower in the band, in the hopes of 
avoiding GPS interference, at least for now.  GPS interests are still 
skeptical, and are still fighting.

Anyway, whatever corporate opportunism has been engaged in by LS and 
its owners, the fault here lies firmly with the FCC, not with LS and 
supposed bribes and back room deals.  As usual, conspiracy theories 
are readily explained by simple incompetence.
