  18. 22. Cisco WCS Location <ul><ul><li>Ability to locate any 802.11 active device </li></ul></ul><ul><ul><li>Accuracy: </li></ul></ul><ul><ul><ul><li>90% to within 10 meters, 50% to within 5 meters </li></ul></ul></ul><ul><ul><ul><li>Depends on environment characteristics and calibration </li></ul></ul></ul><ul><ul><li>On demand, one device with Cisco WCS alone </li></ul></ul><ul><ul><li>Up to 2500 devices with Cisco Location Appliance </li></ul></ul><ul><ul><ul><li>30-day history (configurable) </li></ul></ul></ul><ul><ul><li>Can identify and locate non-802.11 interference with Spectrum Intelligence sensor </li></ul></ul>
  19. 23. Location Tracking Methods <ul><li>RF Closest AP </li></ul><ul><ul><li>Pro: Simple, with no new technology requirement </li></ul></ul><ul><ul><li>Con: Limited accuracy, since an AP can easily cover several thousand square feet </li></ul></ul><ul><li>RF Triangulation </li></ul><ul><ul><li>Pro: More accurate than a single RF RSSI </li></ul></ul><ul><ul><li>Con: Limited accuracy; does not account for effects of building material which may cause reflection, attenuation or multipath </li></ul></ul><ul><li>RF Fingerprinting </li></ul><ul><ul><li>Pro: GPS-like accuracy </li></ul></ul><ul><ul><li>Con: More comprehensive (requires RF prediction tools) </li></ul></ul>
  20. 24. Location Tracking Using Closest AP
  21. 25. Location Tracking Using Triangulation
  22. 26. Location Tracking Using RF Fingerprinting <ul><ul><li>RF fingerprinting traces signal strength for every signal heard by a Cisco AP in the network, which allows accounting for reflection and multipath. </li></ul></ul><ul><ul><li>Then a RF fingerprint is created from every point on the coverage map, which allows Cisco WCS to accurately place an icon and create a probability color grid. </li></ul></ul>
  23. 27. Cisco WCS Location Without Appliance
  24. 28. Cisco WCS Location with Appliance <ul><li>Cisco WCS with Location and Location Appliance accuracy </li></ul><ul><ul><li>90% to within 10 meters, and 50% to within 5 meters </li></ul></ul>
  25. 29. Searching for a Device
  26. 30. Search > Clients
  27. 31. Search > Clients (Cont.)
  28. 32. Recent/Present Map
  29. 33. Summary <ul><ul><li>The home page for each user consists of tabs that can be personalized. </li></ul></ul><ul><ul><li>Cisco WCS also has a Monitor menu, where each type of device can be verified. </li></ul></ul><ul><ul><li>An alarm dashboard can give an alert in case of an unusual event. </li></ul></ul><ul><ul><li>Controllers can be monitored and managed. </li></ul></ul><ul><ul><li>APs can be verified individually or through a network summary. </li></ul></ul><ul><ul><li>Detailed information about clients can be displayed. </li></ul></ul>
  30. 34. Summary (Cont.) <ul><ul><li>Each security-related event can be checked before you take further action. </li></ul></ul><ul><ul><li>Cisco WCS has a summary page where alarms are grouped and displayed, even when the alarm-triggering event is not in the network anymore. </li></ul></ul><ul><ul><li>All events can be accessed and assigned to different administrative users, depending on their nature. </li></ul></ul><ul><ul><li>Cisco WCS has a location capability to identify the position on a map of any wireless device. </li></ul></ul>
