This communication presents a study showing that cellular phone usage duration have got a significant effect on the power control in mobile cellular networks. This is because the long-time operation (transmitting and receiving) of the cellular phone radio hardware cause the wearing-out of radio elements. Hence, the operation of worn-out radio elements introduces power control errors and this degrades the performance of the power control algorithms. And this result in poor power control of the excessive transmitted power, hence the interference caused, compels a handset to violate the EMC regulations. This degrades the quality of the mobile cellular services. The paper also presents a derived power control performance model for a handset.
This paper investigates the effect of microwave oven power output on the data channels of base stations installed near residential buildings. The experimental interference results, shows that the performance of base station data channels hi close proximity to microwave oven are significantly degraded.
This paper introduces a new practical theory implementing antenna polarization to improve the co-channel interference reduction in mobile cellular systems such that when this approach is combined with the already existing reduction methods, the interference reduction degree will improve for the better
