Abstract: Propagation Modeling is required to provide a reliable and efficient planning of cellular network. In this Study, various propagation models like COST-231 Hata, ECC SUI are used to compute the path loss for WiMAX at 2.3 GHz in dense urban and sub urban environment. AWAS Numerical Method compares the path loss with these empirical models. The Path Loss by AWAS Code is appeared as very high because of the regular variations in Near Field Distribution at 2.3 GHz. It can be controlled by allowing the Near field distribution with a limited height of base stations.

Abstract: Jitter is undesired deviation from periodicity of an assumed periodic in Electronics and telecommunication often in relation to reference clock source. The observation of jitter can be characteristics of frequency of successive pulse, signal amplitude or phase of periodic signal. Jitter period is the interval between two times of maximum effect (or minimum effect) of a signal characteristics that varies regularly with time. Jitter may be caused by electromagnetic interference (EMI) and crosstalk with carriers of other signals. Jitter can cause a display monitor to flicker, affect the performance of processors in personal computers, introduce clicks or other undesired effects in audio signals, and loss of transmitted data between network devices. The amount of tolerable jitter depends on the affected application. Thus jitter has important role in designing all routing protocols for MANET.
