Why is it Secure?

Radio Frequency

The RF technology we use for wireless WAN links is part 802.11 standard and part proprietary. This means that the only way you could talk to one of the units is with another unit from the same manufacturer. They incorporate proprietary data scrambling techniques with its advanced air interface preventing decoding. They also use the most secure encryption technique available, which is Advanced Encryption Security (AES). AES has no known weak spots/keys and to this day has never been cracked, so reliable in fact, that it is used by the American military. On top of this, standard network solutions such as secure tunneling and VPNs are supported. We can provide full white papers to further ease security concerns.

Firstly, apart from laser power standards, there are no standards that FSO manufacturers have to follow. So, wavelengths and beam divergence differs from one manufacturer to another. This means that to receive and decode a laser signal, it is likely a head from the same manufacturer would be required.

Our narrow beam FSO systems have a beam diameter typically of only a few meters in diameter at the target location. This is another reason why it is extremely difficult to intercept the communication path of an FSO system. The intruder would need to know the exact origination or target location of the (invisible) infrared beam and be able to intercept the beam within the very narrow angle of beam propagation. Even more difficult, the intruder must have free and undisturbed access to the installation location of the FSO transceiver and be able to install electronic equipment without being observed.

The direct interception of an FSO beam between the two remote networking locations is basically impossible because the beam typically passes through the air at an elevation well above ground level. Due to the fact that the transmission beam is invisible and that any attempts to block the beam would occur near the FSO equipment terminus points, the transmission process imposes another obstacle.
