The Cisco® Wireless Location Appliance is the industry's first location solution
that simultaneously tracks thousands of devices from directly within the WLAN
infrastructure-bringing the power of a cost effective, high-resolution location
solution to critical applications such as high-value asset tracking, IT
management and location based security. By providing the ability to integrate
tightly with a spectrum of technology and application partners through a rich
and open application programming interface (API), this innovative appliance
facilitates the deployment of new and important business applications. These
capabilities make the Cisco Wireless Location Appliance a critical must-have for
all enterprise class WLANs today.
PRODUCT OVERVIEW
The Cisco Wireless Location Appliance is an innovative,
easy-to-deploy solution that uses advanced RF fingerprinting technology to
simultaneously track thousands of 802.11 wireless devices from directly within
a WLAN infrastructure, increasing asset visibility and control of the
airspace. Additionally, the appliance records rich historical location
information that can be used for location trending, rapid problem resolution
and RF capacity management. By enabling the deployment of powerful
location-based applications such as Enhanced 911 (E911) services, asset
management and workflow automation through integration with the Cisco Wireless
Location Appliance API, the appliance becomes a critical solution for
customers ranging from enterprises to vertical industries such as healthcare,
finance, retail, manufacturing and federal organizations.
By design, the Cisco Wireless Location Appliance is
directly integrated into the WLAN infrastructure to lower customers' total
cost of ownership and extend the value and security of the existing WLAN
infrastructure by making it "location aware". The Cisco Wireless Location
Appliance uses Cisco Wireless LAN Controllers and Cisco lightweight access
points to track the physical location of wireless devices to within a few
meters. Moreover, the centralized WLAN management capabilities and intuitive
GUI of the Cisco Wireless Control System (WCS) are extended for managing and
configuring the Cisco Wireless Location Appliance, making setup fast and
intuitive.
PRODUCT ARCHITECTURE
The Cisco Wireless Location Appliance uses the same Cisco
lightweight access points that deliver traffic as location "readers" for
802.11 wireless clients and Wi-Fi tags. These access points collect
received-signal-strength-indication (RSSI) information from all Wi-Fi devices,
including Wi-Fi enabled laptops, voice handsets, Wi-Fi tags, rogue
(unauthorized) devices and rogue access points. The collected RSSI information
is then sent through the Lightweight Access Point Protocol (LWAPP) to the
Cisco Wireless LAN Controllers or certain wireless integrated switches. The
Cisco Wireless LAN Controllers then aggregate the RSSI information and send it
to the Cisco Wireless Location Appliance through Simple Network Management
Protocol (SNMP).
The Cisco Wireless Location Appliance performs location
computations based on the RSSI information received from the Cisco Wireless
LAN Controllers. The Cisco Wireless LAN Controllers that gather the RSSI
information must be associated with the Cisco Wireless Location Appliance
