T he primary problem in today's cellular network is to raise bandwidth efficiency of cellular system and handle blocking in the call between the subscribers. This will be done by improving the performance of system and reducing the interference to allow the users to achieve higher data rat e. T his designed system shows how to increase bandwidth efficiency and enhancement blocking probability in cellular system by using techniques of Dynamic Frequency Hopping where data transmission of the wireless regional area network system are performed in parallel with spectrum sensing without any interruption. This leads t o an enhancement in performance of system and diminish the interference allowing the users to attain hig her data rate.
