Bridging the Gap Between Wi-Fi, Active RFID and RTLS



The AeroScout suite of products provides Enterprise Visibility Solutions using Wi-Fi wireless networks as an infrastructure. AeroScout solutions use standard wireless networks to accurately locate any asset, and utilize that location to deliver direct benefits such as asset tracking, process automation, theft prevention and increased utilization. AeroScout pioneered the Wi-Fi-based visibility market. The company introduced the industry's first Wi-Fi-based Active RFID tag, and continues to lead the market with the only Wi-Fi visibility system to enable multiple modes of location. Unlike competing technologies, the AeroScout system was designed to work in practically any environment (both indoors and outdoors, with TDOA and RSSI methods), and with the flexibility to meet numerous application needs.



How does the AeroScout System work?


  1. AeroScout's Wi-Fi-based Active RFID tags and/or standard Wi-Fi devices send a tiny wireless signal at a regular interval.
  2. The signal is received by standard wireless access points (or AeroScout Location Receivers), without any infrastructure changes needed, and is sent to a location processing "engine".
  3. The engine uses signal strength and/or time of arrival algorithms to determine location coordinates, and sends this data to AeroScout MobileView.
  4. AeroScout MobileView uses location data to display maps, enable searches, create alerts, manage assets, work with third parties, etc.


Key Benefits

Multiple location modes to suit all needs.
AeroScout is the only Wi-Fi visibility system to offer multiple location types with a single infrastructure: real-time location, presence detection, choke-point visibility and telemetry.

Standard Wi-Fi infrastructure.
The AeroScout system utilizes standard wireless networks for its communications protocol, keeping the infrastructure cost low and enabling enterprises to gain more benefit from their existing WLAN.

Visibility of any valuable asset with AeroScout Wi-Fi-based Active RFID tags.
Locates small, battery-powered AeroScout Tags that can be used to track people and a variety of assets and equipment. The AeroScout system can also locate standard Wi-Fi devices such as laptops, handhelds and scanners without the need for tags.

Enterprise-class application platform for location-based services.
AeroScout MobileView is an industry-leading end-user application for visualization, asset tracking, alerting and reporting, as well as an integration platform for developers to design and deliver location-based services to third-party applications. MobileView turns location information from any source into everyday business value.

Accurate, reliable real-time location and presence detection.
Unlike proprietary Active RFID systems, AeroScout provides true real-time location based on both accurate Time Difference of Arrival (TDOA) and Received Signal Strength Indication (RSSI) methods.

Integrated RFID choke-point and telemetry functionality.
AeroScout Exciter hardware enables RFID-style choke-point tag detection, telemetry message retrieval and other functions.

Indoor and outdoor operation.
The AeroScout system is suitable for use in both indoor and outdoor environments, from corporate offices to harsh industrial areas.
