Innovative RF localization for wireless video capsule endoscopy

Radiofrequency (RF) localization is used in many fields of daily routine of almost everyone. It is becoming crucial application in many fields, starting from industry to everyday life. Location is calculated using radio waves in many applications such as GPS system, indoor localization using WLAN system, localization based on mobile network parameters like A-GPS system, or localization in warehouses using RFID tags. In this work, we present radiofrequency localization of endoscopic smart pill inside human body used for visual imaging of human gastrointestinal (GI) tract. This kind of visual imaging can bring significant benefit to the medical doctors and patients, if there would be a possibility to localize the pill, while moving through the GI tract. Frequency band proposed for this application is MedRadio band (401 - 406 MHz) and ISM band (2.4 GHz). Finally, the patients and medical staff would welcome standardization in the field of endoscopic pill and its localization.
