BANs are disturbed by several kinds of wireless communications, as mobile cells or Wi-Fi systems. Thus the wireless optical technology could be considered as a solution to reduce the interference amount. The validity of such a solution is examined in terms of transmitted power and data rate. The novelty of this paper is that this is the first time where diffuse optical wireless technology is considered to achieve “on body” communication, using the multiple reflections of optical beams in the patient room.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131137487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents the SOA operation using the segmentation model that utilizes the rate equation employing the ASE noise. The impact of ASE noise on the total SOA gain response in absence and presence of input signals is investigated. Also the impact of ASE noise on SOA length for a single pulse and a packet of pulses and making comparison between them are introduced. As well as studying the dependence of gain uniformity on SOA length under the influence of ASE noise is clarified by calculating the gain standard deviation.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126165306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For line-of-sight links, comparison is made between a collimated and a diffused beam. The results demonstrate that the transmitter beam divergence has a significant impact in the transmission in clean seawater compared to turbid water. The bandwidth that can be achieved for line-of sight links is estimated to be around 100 MHz in turbid water and much higher in clean water. For non-line-of-sight reflective links the bandwidth is severely limited to around 20 MHz in clean water.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"566 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125919611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
