ABSTRACT
The application of communication theory for the wireless environment is a rich subject, that calls for continuing research and involves many diverse aspects of practical and theoretical importance. A mobile system is defined as a radio communication network that allows continuous mobility through many cells. Wireless communication implies radio communication without necessarily requiring the handoff from cell to cell during the conversation. Electromagnetic propagation in mobile outdoor and indoor environments is a complex and challenging phenomenon. The design of a communication system and the choice of channel must take into consideration the fact that the transmission of a large amount of information in a short time interval requires a wide bandwidth system to accommodate the signals. Radio propagation in a mobile communication environment, outdoors, or indoors is certainly a complex phenomenon.
