Implementation
- Easy installation.
- High bit rates and low latency.
- Low data corruption and error rates at the bit level.
- Immunity to electromagnetic interference.
- Transparent protocol
- High security in data transfer due to the high directionality.
Advantages
Some details
Data receiver
- It consists of a solar panel used by reversing the polarity.
- Acting in a similar way to a photocell but with a considerably larger area of action.
D-Tlaser
- Laser base device.
- The device involves a data sender and a data receiver.
- It consists of a laser controlled by modulation. (AM, PM, FM, DSB, SSB, SSB, VSB, QAM, DMT, etc)
- The modulation allows to transmit information in digital form under a certain codification.
Data sender

2018
- Solves most of RF(WIFI, etc) problems
- Very easy and quick to install.
- High bit rates.
- Low data corruption and error rates at the bit level.
- Immunity to electromagnetic interference.
- The implementation is already working.

The magnetosphere.
too much noise !!
- The mars magnetosphere is too weak.

Who we are ?

but...
- has very weak magnetosphere !
- Mars has an ionosphere

- The information requires a medium of propagation.
- The propagation medium must be free of noise as possible.

Data comunication
- Regardless of the physical media.
- The communication of data requires a minimum set of elements
- Low data rate for a given spectral band.
- Spectral band saturation.
- Low power-efficient.
- Atmospheric propagation effects.
- High data corruption rate.
RF and WI-FI can solve the problem ?
The CHALLENGE
We need high speed, low corruption data transfer
- It’s only a matter of time before we are able to go to Mars
