Determining optimal power, location and direction of transmitters using a genetic algorithm

Electromagnetic field pollution caused by various human-made sources can pose a health hazard, especially in urban and dense populated areas. Many independent service providers install new electromagnetic sources (transmitters) usually without mutual coordination. In this paper an investigation is presented for adjustment of transmitters´ parameters (e.g. location, direction, power) to minimize a health hazard caused by the electromagnetic radiation while in the same time satisfy service availability (minimal reception of electromagnetic field strength for each provider). In this research two transmitters with a different nonuniform radiation diagrams were positioned within the observed area and their parameters were adjusted (power, direction, position) taking into account electromagnetic field constraints in areas where people reside. Using here proposed GA aided method for transmitters´ parameter adjustment promising results were achieved.
