gracias kalash,

ya sabes que mi interés especifico es hacer llegar internet a un cierto
lugar... :)
1.4km no es suficiente creo... ;)

>> laser communications protocols between the moon and the Earth with results
>> anticipated to be approximately 3000 times faster than traditional radio
>> communication technologies.

>> 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.

>> less power than current radio technology. Cloud cover can impede this type

>> 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

>> 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.
