To address these fundamentals, the authors use capsule endoscopy as an example application. The authors first provide the results of the Cramer Rao Lower Bound (CRLB) for received signal strength (RSS) based endoscopy capsule localization, inside the human body, using existing path-loss models for radio propagation. Then challenges demanding further research are highlighted for attaining more precise localization using the time-of-arrival (TOA) based ranging techniques.<\/p>","DOI":"10.4018\/jertcs.2012070102","type":"journal-article","created":{"date-parts":[[2012,12,11]],"date-time":"2012-12-11T11:30:23Z","timestamp":1355225423000},"page":"18-37","source":"Crossref","is-referenced-by-count":12,"title":["Challenges in Channel Measurement and Modeling for RF Localization Inside the Human Body"],"prefix":"10.4018","volume":"3","author":[{"given":"Kaveh","family":"Pahlavan","sequence":"first","affiliation":[{"name":"Worcester Polytechnic Institute, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunxing","family":"Ye","sequence":"additional","affiliation":[{"name":"Worcester Polytechnic Institute, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruijun","family":"Fu","sequence":"additional","affiliation":[{"name":"Worcester Polytechnic Institute, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Umair","family":"Khan","sequence":"additional","affiliation":[{"name":"Worcester Polytechnic Institute, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"jertcs.2012070102-0","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2006.1613745"},{"key":"jertcs.2012070102-1","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2009.2014531"},{"key":"jertcs.2012070102-2","unstructured":"Aoyagi, T., Takada, J., Takizawa, K., Katayama, N., Kobayashi, T., & Yazdandoost, K.
