communication solution. Ancient Chinese developed a protection system against the

Mongol tribes, building watchtowers within the line of site to other towers. And as

reflect the sun to the remote towers. In this way the area could be prepared against

the attack in a very short period of time.

The principle used in free space laser transmission is very similar to the one is used

for fibre optic transmission. The difference is while fibre optic devices

and optics optimized for transmission to the air. Also one can observe to the

similarity in the transmission properties. No galvanic contact, no ground

need for surge protection, noise immunity, long distances, high bandwidth.

changing parameters. For instance while the attenuation of an optical fibre is

dramatically (depending on the weather conditions).

There are several things that can influence the quality of transmission. We can

Nevertheless, as a general rule it is very important to select the installation site so

that nobody can look directly into the transmitter. For this reason place the head

so high (on the side wall of the building) or so close to the edge of the building

(on a parapet on the rooftop) that no person can approach it accidentally and can
