Abstract :
In this paper, a dynamic modulation scheme for LMDS (local multipoint distribution service) is presented. The link budget at 26 GHz is calculated. In a sectorized cellular system, considering inter-cellular interference in addition to the link budget, C/I contour curves are drawn. These curves are used as a criteria for the dynamic modulation scheme
