Healthcare information technology developer McKesson announced the general availability of the Horizon Real-Time Location System. The product uses a hospital’s existing 802.11 Wi-Fi network, active radio frequency identification (RFID) technology, and software to instantly track the location and movements of critical assets and hospital personnel, according to the San Francisco-based company.

McKesson says its small, active RFID tags are affixed to high-value assets or to key individuals, and send signals over the wireless network to a location engine that uses software to map and report the tag locations on a geospatial view of the hospital. The system condenses this data into meaningful text and graphical images, according to the company.
