The AeroScout Engine is a software component of the AeroScout Visibility System, which enables location-based applications in a standard wireless LAN environment. The AeroScout Engine processes information received from wireless Access Points to produce accurate and reliable location and presence data for assets tagged with AeroScout's Wi-Fi-based Active RFID Tags. The sophisticated processing abilities of the AeroScout Engine make it the cornerstone of the most complete and flexible visibility solution on the market.

Core capabilities of the AeroScout Engine include highly accurate Wi-Fi positioning, management of AeroScout hardware and software setup, and in-depth analysis tools.

Key Benefits include:

• 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.
  
• Visibility of any valuable asset with AeroScout Tags. Locates small, battery-powered AeroScout Tags that can be used to track people and a variety of assets and equipment.
  
• Visibility of standard Wi-Fi clients, without modifications. AeroScout locates Wi-Fi clients such as laptops, PDAs, barcode scanners and other wireless devices without the need for any hardware or software modifications. This eliminates a major management challenge.
  
• Accurate, reliable real-time location. Uses Time Difference of Arrival (TDOA) and Signal Strength (RSSI) algorithms to determine location of devices. Unlike competing systems, AeroScout's technology provides accurate and reliable real-time location with a low total cost of ownership.
  
• Integrated RFID choke-point functionality. AeroScout Exciters trigger transmissions from AeroScout tags as they pass through doorways, gates and other choke-points. This enables RFID-style tag detection, telemetry message retrieval and other functions.
  
• Integrated telemetry capability. AeroScout tags can retrieve wired serial data from vehicles and other sources, and transmit it to the AeroScout Engine.
  
• Indoor and outdoor operation. The AeroScout system is suitable for use in both indoor and outdoor environments, from corporate offices to harsh industrial areas.
  
• Standard Wi-Fi infrastructure. The AeroScout system utilizes standard wireless networks from multiple leading networking vendors for its communications, keeping the infrastructure cost low and enabling enterprises to gain more benefit from their existing WLAN.
