[un/loquer] Fwd: How the Latest NASA Launch Can Change Communication

[Fabio Barone]

un articulo que habla sobre la transmisión de datos sobre una linea laser,
en lugar de usar ondas radio. y explica de los problemas de la transmisión
radio, wifi, etc.

pregunta:
esta es la NASA. hay alguna posibilidad de reproducir una tecnología
similar "de garage"/ de cacharreo a escala mas pequeña y mas barata, con el
fin de conexiones rapidas? O es pura ilusión. :)

       How the Latest NASA Mission Can Change Communication

Last month, NASA launched the Lunar Atmosphere and Dust Environment
Explorer (LADEE).  The mission included a prototype to test long range
laser communications protocols between the moon and the Earth with results
anticipated to be approximately 3000 times faster than traditional radio
communication technologies.

The radio technology used today is not much more advanced than what was
used during the Apollo missions of the 1960’s.  The LADEE mission hopes to
break this cycle by introducing new technology capable of revolutionizing
communications both in space and here on the ground.

LADEE was scheduled to reach a lunar orbit on October 6th.  Unfortunately,
the government shutdown has made finding information about the mission
nearly impossible.  The LADEE mission homepage greets visitors with a
canned message about the federal budget; yet another unfortunate side
effect of the government’s inability to put citizens first.

The mission brings with it the promise of high-speed data transmission – as
much as 200 Gbps.  Better yet, the technology uses approximately 25% less
power than current radio technology. Cloud cover can impede this type of
data transfer, however, LADEE has redundant ground stations throughout the
country meaning weather conditions are unlikely to affect the system.

For comparison’s sake, let’s take a look at current radio technology and
some of its limitations as a communications tool.
 Current Radio Communications Systems

Most modern communications systems rely on radio waves for transmission.
Even in communities where fiber optic transmission lines are the norm, the
end-user typically relies on radio waves in the form of Wi-Fi.

Although there have been significant advancements in Wi-Fi technology in
recent years, there are quite a few limitations that are beginning to
manifest themselves as our need for information continues to grow.

In general, radio technology is:

*Slow* – Compared to the laser technology promised by LADEE, radio waves
cannot compete in terms of speed.  As we continually rely on more
data-intensive applications, speed is becoming even more important than it
has been in the past.

*Capacity* – Many experts have stated that current radio technology is
already at capacity.  In other words, we are consistently exceeded the
bandwidth allotted by these systems and growth from this point forward is
marginal at best.

*Security Concerns* – Wi-Fi and other radio based signals are easily jammed
or intercepted.  Online fraud and identity theft are at an all-time high.
Much of this crime can be attributed to compromised wireless networks.  For
example, the massive TJX credit card theft a few years ago was accomplished
when hackers gained access to an unsecured Wi-Fi network at a retail
location.

*Damage* – In 2008, most of the Middle East and India lost all Internet
access after trans-Atlantic fiber lines were severed.  The current
infrastructure is susceptible to damage from natural disasters, terrorist
attacks, and hardware failure.

*Signal Degradation* – Radio communications degrade quickly across
relatively short distances.  The technology being tested by NASA allows for
communications across vast distances quickly and reliably.

Right now, approximately three billion people do not have access to
Internet service.  LADEE could bring global connectivity to these
communities quickly and easily.
 Your Daily Life

How will this technology change your life? Simply speaking, it’s the next
wave of internet connections.

Laser cables are already being used by internet providers, but this will
move the same light transmissions over the air. It creates an endless
number of high-speed uses and applications.

Remember, leveraging proper technology is the key to becoming independent.
Right now, there are approximately three billion people we cannot
communicate with easily.  Is it safe to say we could probably learn a thing
or two about resiliency from these communities?  A new gardening
technique?  Better food preservation methods?

The possibilities are endless.

Faster, more reliable connections with more people around the world means
we can work together more easily. Even existing lines of communication are
improved as information transmission methods improve. Collaboration becomes
a convenient reality

The LADEE technology is capable of transmitting so much data simultaneously
that it would be the equivalent of 100 HD television shows.  Think of how
much more data could be shared with like-minded individuals around the
world?

Right now, O3B (the Other 3 billion), a global telecommunications company,
is working to supply reliable communication to many communities without
Internet access.  Current initiatives rely on radio technology but the
company is already looking at alternatives thanks to the research being
done by NASA and the LADEE mission team.

Other companies are also looking at this mission as a glimpse into the
future of radio telecommunications.  Whether LADEE is a success or not,
it’s clear that the demand for improved communications standards is
increasing.

Although we cannot depend on technology like this forever, we are
well-served to leverage it when possible to further our knowledge and
simultaneously lessen our dependence on a failing system.
