The technological advancements in digital communication and computer technology have paved the way for all pervading World Wide Web based internet. The development and deployment of 4G technology based mobile communication has provided a powerful multimedia communication device for users. The multimedia signals are alphanumerical text signals, audio signals including speech and music, and video signals including still and moving images. Transducer based sensor data may fall under any one or more of the above categories of signals i.e. text, audio and video. Sensor networks have emerged as an integral part of information technology. In this paper analysis of image compression using Haar and Db-2 Wavelet Transform with median filter and flat fading is used as wireless channel for transmission of image on wireless medium with QPSK modulation. Performance of these systems is measured by BER verses SNR
