    This thesis studies the differences between xDSL, LMDS, Fiber and FSO. Cable access system XDSL is compared with the optical fiber access communication method. As wireless access communications, LMDS and FSO systems are compared. Finally, a full comparison of all the key points for all the access systems are made. Issues compared cover the state of the art, information rate, communication distance, security, commercial prices, and the system installation costs. The comparison is supported by a software which is running under Unix systems on the internet. In the second part, atmospheric structure and the atmospheric molecular effects on the light waves in different ranges are studied. Temperature, C02 and water molecular effects in the atmosphere and the effects on the intensity are also studied
