UMTS LTE downlink cell size calculation

This paper deals with cell size calculations for UMTS LTE downlink. As LTE uses adaptable modulation technique, the possibility to use various modulation techniques in cells with different size was analyzed. At the basis of Okomura-Hata propagation model, the equation for maximal cell radius was calculated taking into account the height and gain of both base station and mobile station antenna, transmitter power and losses and receiver sensitivity and losses. Various simulations were performed to give insight into signal propagation in European urban and suburban area. At the basis of simulations it is shown for these areas that UMTS cell structure and size can be used also for LTE cells which will be covered with 64QAM modulation.
