December 5, 2008, Newsletter Issue #170: Free Space Optics: The Newest In Wireless Technology

Tip of the Week

Free space optics (FSO) is the newest alternative to sending information through wires or via radio frequency. This technology sends data through laser beams that are pointed at mirrored telescopes, which in turn continue to carry the data until it reaches its destination. This process of communication is much faster than light traveling along wires or even radio waves. In fact, the technology is so fast and unobtrusive, it doesn't require a spectrum license, such as radio operations do. The only drawback to FSO technology is the poor performance in a foggy atmosphere. The dense, moist particles in the air interrupt the signal for a short while. However, it still remains the fastest way to send large amounts of data with wireless technology.
