Wi-Fi-Based RFID Improves Elderly Care

PresCare is using a Wi-Fi-based RFID system to enable its residents to quickly and easily call for help, and to alert staff if a resident wanders into a dangerous area.

Aug 08, 2007PresCare, an Australian provider of elderly care, is using a Wi-Fi-based RFID system to enable residents to quickly and easily call for help when they need it. The medical alerting system notifies caregivers any time a resident wanders into a dangerous area or hasn't moved for a long time, indicating they might need help.

PresCare operates five facilities and two community centers in Queensland. The company is using active tags and related hardware and software from San Mateo, Calif.-based real-time location system (RTLS) provider AeroScout.


A resident and staff member at PresCare wear the Wi-Fi-based RFID tags.
The AeroScout system includes active 2.4 GHz RFID tags; exciters, which activate the tags, causing them to transmit their identification numbers; and the AeroScout Engine, which calculates tag locations by processing data from the tags and various Wi-Fi access points. The system also includes AeroScout's MobileView software, which can portray location information on a map, in a table or in a report. Surecom, a local company, served as the systems integrator for the implementation.

PresCare began implementing the RTLS in mid-January at its Mount Tamborine site, says Ash Hanna, Surecom's CEO, and has been running it since the beginning of February. About 100 tags are in use, says Joshua Slobin, AeroScout's director of marketing. Affixed to lanyards that can be worn around the neck, the tags measure approximately 2 by 1.5 inches and a half-inch thick.

The tags are water-resistant and feature large, easy-to-find call buttons that residents can press when they are in trouble or need assistance. "PresCare wanted an emergency-alerting system that would give their residents full range of motion," Slobin says. "They can go anywhere in the facility and not have to be necessarily watched over at all times—but if there was an emergency, they could press a button that would send an alert." PresCare staff also wear the tags so they can easily issue an emergency alert.
