Ernesto Hernandez Busto at Penultimos Dias takes a long
look at one of the most interesting nuggets in the Associated Press story about USAID contractor Alan Gross’ modus operandi in Cuba: the
fact that he reportedly used a special SIM card available only to government
agencies to make his satellite Internet installations less susceptible to
detection by Cuban authorities.
This, Ernesto notes, is important because it opens the door
to the argument that Gross was engaged in espionage or linked to intelligence
agencies.
Gross was not charged with espionage nor did the the Cuban
court link him to intelligence activities.
The court’s sentencia only
mentions SIM cards in the very long list of Gross’ seized equipment and
accessories that have been duly passed on to Cuba’s communications ministry:
three BGANS satellite gizmos with their SIM cards, 13 Blackberries with their
SIM cards, and a plastic bag with five SIM cards for telephones.
Nonetheless, Ernesto raises interesting questions about the
SIM card issue and has consulted an unnamed expert (whose comments he quotes in
English) who doubts the veracity of the AP story regarding the SIM card. Ernesto also cites AP reporter Desmond Butler
standing by his story.
Considering that Gross’ trial is ended, Cuba knew what he
was doing, and USAID insists that there is nothing covert or classified about
its operations, I think more information would be helpful here. USAID’s m.o. is a subject of legitimate
public policy debate, of interest to both fans and skeptics of USAID’s
activities. It is strange for the U.S.
government to allow it to proceed with abundant information provided by Cuba,
some leaked information reported by AP, and only bland generalities from
USAID.
Ernesto’s questions deserve answers, as do others. Such as whether USAID has a policy about its
operatives using private American citizens and organizations as cover, without
informing them, for activities that could land them in the same trouble in
which Mr. Gross finds himself now.
On a related note, this article in
the Forward
suggests that one of the groups that Gross enlisted to carry some of his
equipment was the Jewish Federation of Broward County.
Hernandez Busto also claims that all Gross was doing was creating a “BGAN Private Network” as described here, but in fact that is something completely different, as a careful reading of the linked page makes clear.

Update: A reader
sent in the following:
In his attack on the
reporting of Desmond Butler of the AP, Ernesto Hernandez Busto argues that the
BGANs Gross was deploying were perfectly ordinary, and quotes an anonymous
expert who says that only a special cell phone using a military network would
have the capability Butler described, and it’s not plausible that Gross had
access to such highly classified technology.
This expert is just wrong. There is such a thing as a discrete SIM card that has exactly the capabilities Butler described. It has nothing to do with cell phones or military satellite networks. It fits a regular BGAN terminal, and appears to only be available to government purchasers. See this description (esp. slides 16-18) of how it works in a sales presentation prepared for government agencies. This special SIM card stops the BGAN from reporting its GPS location to the satellite; instead, it reports the location within a 100-300 kilometer radius.

Los BGANs, cuando se usan, reportan su
posición GPS al satélite. Todas las transmisiones de BGANS al satelite y de
vuelta son codificadas.
Pero el Pentagono, para estar más seguro aún de que las posiciones físicas de sus unidades que usan BGANs no pueden ser interceptadas y delatadas, hace varios años empezó a usar SIMs “discretos” porque no transmiten las posiciones GPS. Es decir, aunque se lograra interceptar y decodificar una señal BGAN, no se podría saber la posición del aparato.
Ya casi no se usan los SIMs discretos porque al no recibir las posiciones GPS, el satélite no sabe de dónde viene lo que esta recibiendo y no puede ajustar el poder de sus trasmisiones. (Si el satelite sabe que está recibiendo data de posición X, donde sabe que su cono de transmision es débil, puede maniobrar para aumentar el poder de su transmisión.)
El uso de SIM discretas esta muy pero muy restringido a militares, servicio secreto, etc.
Que le hubieran entregado una a Alan Gross, quien se supone es sólo un subcontractor de USAID, sería muy extraño.

unnamed expert -- an oxymoron, like army intelligence. believe the person who puts his name of what he has written, and not the one who says things with no accountability
(and yes, i know the irony of now signing this anonymous.
