Abstract/Summary
The portable laser communication device (PLCD), is a low cost system used to set up networks in data isolated regions via an optical line-of-sight communications protocol. In this manner the PLCD transmits at 9600 baud using UART protocol over the visible light band at 635nm. The device is intended to operate in indoor conditions and be semi-permanent until redeployed. The PLCD is built as a transmitter, receiver pair and when installed, utilizes tracking to find each other and automatically set up communication within a window of 30° laterally and 10° vertically. Each side of the system is less than 15 lb and portable with a volume of 1 cubic foot to allow for minimum bulk when transporting the device and installing it. The PLCD pair will communicate over lengths around 50 meters. The system latency does not exceed 30 ms and the system can interface with external USB devices. The PLCD does not exceed 6W in power consumption.
