【 摘 要 】

iLoc is an ultrasound ranging based indoor localisation system which is deployed at the iHomeLab laboratory. Currently the system is used for person tracking: Persons to be tracked get an electronic name badge comprising an ultrasound transmitter. This badge can be localized with an average accuracy of less than 10 cm deviation in its spatial position, by means of reference nodes distributed in the lab rooms. Depending on the position update rate, a small battery may suffice for several month of tag operation. Also the badges are equipped with a low power information display. Other advantages when compared to existing ultrasound ranging systems (like CRICKET, CALMARI, BAT) are for example the simple deployment with its 2 wire "IPoK" bus system.
