14 Then, Augment with Real Time Locating System (RTLS) 14 Avoid GIGO RTLS Technologies Infrared (IR) based The IR signal is bound by walls and can be tightly focused. IR provides accuracy Low-Power RFID RF signals for general location and communication WiFi based Ultra-wideband

15 How Does it Work? 15 Tags Readers Visibility Engine AeroScout Tags and Mobile Devices 2.4GHz Communications AeroScout Engine or appliance Active RFID tag send a tiny 2.4GHz RF signal at a regular interval Signal is received by the AeroScout Location Receivers and is sent to an AeroScout Location Engine The Engine uses multiple algorithms to determine location, and sends asset data (location, status, etc.) to enterprise software Enterprise software uses location and status data to display maps, enable searches, create alerts, manage assets, etc. Real Time visibility tailored to different functions: alerts to these who need to act, notification to those in a need-to-know and reports for general visibility
