With Wireless functionality, we can model both terrestrial and satellite radio Systems. Radio communication is used to implement and administrate the Telecommunication networks. Usually this implementation will takes place at the physical level of the OSI model network. We create a radio network by using modeler and wireless modeling. Also we will observe the quality variations in the received signal. This quality variation arises from radio interference at the accepting node in a powerful system topology. In a wireless system, the obstruction can diminish the sign to commotion proportion (SNR). The SNR in a system can be improved utilizing various sorts of reception apparatuses, for example, directional receiving wires and by expanding the compelling sign quality at the beneficiary. To analyze the performance of the network with jammer device, we will structure a straight forward radio system with a portable jammer hub and two stationary correspondences hubs, and afterward the distinctions in the SNR of the system has been broke down when the stationary hubs utilize a directional receiving wire versus an isotropic reception apparatus. The OPNET Modeler, a network performance analysis software tool is used to create a network model. In this paper we evaluated the receiver BER, received power, and throughput with two antenna patterns. Also a timer controller is designed to compare the situation of the jammer with BER.
