Reva Systems
Combining Active and Passive RTLS into a Comprehensive Solution
Reva Systems applications recognize that no one RFID/RTLS infrastructure technology can meet all the needs of all customers. While not often talked about, active and passive location technologies work well together. They play complementary and synergistic roles in a comprehensive architecture for supporting location-based applications in healthcare environments.
Active RFID systems are increasingly comprehensive in what they can provide to customers; however, passive RTLS fills critical gaps left open by Active RFID’s limitations. Passive RFID platforms like those provided by Reva provide short-range coverage, high resolution, rapid reporting, and allows the tagging of a broad range of assets and supplies where active tagging is impractical, but also provide the bridges necessary to work with active technologies.
The Reva platform provides standardized software interfaces that brings together both active and passive location information can be unified in common RTLS infrastructure.
A Reva solution would include:
- Reva Systems’ Tag Acquisition Processor (TAP)—The core of REVA’s approach is their Reva Systems’ Tag Acquisition Processor (TAP). Reva’s TAP controls passive RFID readers and provides location-based observations of passive tags to application like Aeroscout’s MobileView. The TAP’s Passive RFID Real-Time Location Engine uses data from multiple readers to accurately determine the position of assets with passive tags.
- Passive RFID Readers—Passive RFID readers are installed in locations where passive tags need to be read. Locations include interior and exterior doorways, laundry chutes and supply cabinets. The readers send tag observations to the TAP for processing. Readers are available in a variety of fixed and mobile form factors, and Reva Systems can recommend the appropriate reader(s) for your application.
- Passive RFID Tags—Passive RFID tags are available in a variety of sizes, shapes and styles. Some tags are designed for specific applications, such as IT asset tracking or for use in autoclaves. Reva-4-Healthcare includes passive RFID tags specifically qualified for various healthcare applications.
