The Wonders of Free Space Optics
Can you imagine the possibilities if you could create free space optics (FSO), which are bandwidth connections that use invisible beams of light to transmit information? It's almost like science fiction, but it is very real. This type of connection can send as much as 1.25 GB of information, including data, voice, and video, all at once.
This technology was initially developed by NASA and the US military, which probably isn't surprising. What might be surprising is that it is now available to the general public and operates in a fashion similar to fiber optics, but without the fiber optic cables.
Instead, free space optical communication works via a connection between free space optics wireless units, which each have both a transmitter and a receiver. This means that both units can send and receive data, allowing a two-way flow of information.
The optical wireless unit has an optical source and a lens that can send light through the atmosphere to the lens in another unit. These transmissions will not experience interference from radio frequencies and this type of communication does not require an RF license.
In addition, the system can be upgraded with ease and there are no security software upgrades required. There is also no need for rooftop deployment as it will work behind windows and there are no expensive fiber optic cables to be installed. The bottom line then is lower costs all across the board during operation.
Outdoor Wireless Capabilities
Free space optics has outdoor wireless capabilities. This means that the people who use this FSO technology will have greater mobility and flexibility than they would otherwise have with a fiber optic system.
This type of communication system will have the speed of fiber optics, but without being bound to the use of wires. This type of system is also currently capable of speeds of 1.25 GB per second and has future capability of speeds as high as 10 GB per second.
How is this greater speed possible? Simply because the transmissions will be able to travel through the air faster than through the glass of the fiber optic cables. This allows for speed of light transmission and communication.
Free space optics has a narrow band transmission and because it is very similar to current fiber optic systems the transition from fiber optic communication to free space optical communication will be virtually seamless. This means that outdoor wireless communication will be the way of future for everyone.
