Low Power FPGA Implementation of a Smart Building Free Space Optical Communication System

Free Space Optical (FSO) communication systems have extensively invaded the speed of smart city evolution due to current surge in demand for wireless spots that can match recent challenges high technical leaps evolution. As number users is vastly increasing throughout all networks form machines, devices, and variously distinct objects, FSO a hugely recommended robust system mitigates lot RF disadvantages on field with no need licensing, fast rollout time, low cost. This paper shows an exploit Low Power Field Programmable Gate Array (FPGA) based designed Line Sight (LOS) Building Communication over distance 12 m using 650 nm Visible Light (VL) red laser source via On-Off Keying (OOK) higher-level Intensity Modulation (IM)/Pulse Width (PWM) schemes. The implemented reached doubled data rate than OOK 230 kbps IM technique. Traffic monitoring building security status be frequently updated between adherent buildings, each scanning its zone real-time conditions sharing them neighboring links.
