- Description:
- Free space optical communication (FSO) offers a promising solution to the “last mile” bottleneck of high-speed telecommunications. Data is encoded using a modulated laser and optically sent through the air to a receiving photodetector. Although this requires FSO systems to have direct line-of-sight between the emitter and receiver, this is...
