Real-time location systems (RTLS) have become common in today's hospitals, surgical centers and nursing homes, resulting in cost savings and improved efficiency. From finding key assets in the ED, to optimizing patient flow, to automated billing, RTLS can deliver real benefits across an organization. Typical real-time location systems include: Ultra-wideband (UWB), Wi-Fi, Zigbee and UHF, and they all work in essentially the same manner. Hospital organizations can have the most precise, highest-value location information available by installing UWB RTLS solutions throughout their facilities, and some have, even though the initial investment can be higher than signal-strength systems. However, some hospitals that need a lower cost of entry into the world of RTLS may be required to compromise on accuracy. UWB provides the accuracy of an interaction-grade RTLS where it's needed, and the signal-strength system provides lower cost zone- and room-level accuracy. The choice of which to use is a matter of preference.
