    Low power transmission technology is ones of major concern in new wireless network (NWN) systems. The impulse radio is a potential technology to apply with body area network systems due to its transmit signal as impulse radio, which has low transmitted power. UWB gain high popular attention in short-range wireless communications development. Major kinds of application are able to used with UWB, e.g., wireless medical sensors networks, entertainment devices, and wireless localization. Information transmission in BAN systems is important for a reliable and accuracy in a actual used of medical sensors. In this research, the evaluation of UWB transmission model with human is introduce for analyze a distortion due to human body effect. The template waveform is proposed at the receiver side to achieve high level of SNR. The proposed model is very useful for the evaluation and design of wireless medical sensor networks including actual human body effect.

    Body area network (BAN) is becoming an increasingly important part of the wireless communication system and short range applications. Characteristic of ultra wideband impulse radio (UWB-IR) channel propagation is very important. The human body is more complex than other applications. Therefore, to understand the characteristics of the channel distribution on the human body is so important. This paper presents characteristic of channel propagation due to effect within human body and without human body for wireless applications based on measurement data. The template waveform is considered at the receiver side to maximize the SNR for evaluation. In this paper, the results are evaluated based on the extended Friis' transmission formula. This technique gives very accurate results and is very useful for the design and evaluation of UWB transmission for wireless medical applications, especially focusing on the effect of template waveform.
