Optical Wireless Method

So far we know the information; we only know the Network Operators are using the fiber optic cable, conventional cable or radio waves as transmission media for carry the voice or data communications.
We know that media is sometimes often obstacle by some soil excavation permit such a difficult to get permission / expensive cost because of the areas full by building and also difficulty when using a radio frequency.
We can use the Optical Wireless as solution but the Optical Wireless there is no one solution that we can use it absolutely can replace that media (fiber optic, conventional cable or radio).
In the Optical Wireless we use the laser through the medium of air. But in the fiber optic cable the laser through the medium of fiber for transmission.

Optical Wireless Methods is very effective in terms of installation and cost if we use in urban areas with storey buildings and are well-organized and orderly administration of his city. With the Wireless Optical we can send the data / video or sound within bandwide up to 1.25 Gbps, depending on the application in use. But the method remains have some weakness of the limited mileage because of the influence of the fog / smoke and rain intensity. Maximum distance is 5 km with sunny weather and the straight is not obstructed. For conditions in Indonesia, the optimal distance of about 2 to 3 Km.
Proximity to urban areas is very pretty and will be able to save costs.
