Challenges In Outdoor and Indoor Optical Wireless Communications
نویسنده
چکیده
Optical wireless communications in the outdoor is capable of providing a broadband last mile access, and in the indoor environment it can be used to provide flexible interconnection through wireless distributed data communication systems to connect PCs, digital assistants, laptops, printers, digital cameras in offices, shopping areas, warehouses and manufacturing floors. Optical wireless communications, however, faces many challenges in its implementation because of high loss in the outdoor environment due to adverse weather conditions, maintaining line of sight link due to sway and vibration in the building, and eye safety and multipath effect in the indoor environment. Many solutions have been presented to overcome these challenges. This paper will review these challenges and discuss solutions for indoor and outdoor environments. A hybrid optical wireless/ RF link to overcome the effect of adverse weather conditions and improve link availability will

Indoor Non-directed Optical Wireless Communications - Optimization of the Lambertian Order
For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...
