The Need for “Intelligent RF” Beyond static planning and survey tools The air space is constantly changing…. E.g., Bluetooth device Signal strength Interference Signal:noise ratio Coverage Area Throughput Load E.g., VoIP phone call An Intelligent WLAN system must adapt in real-time: Manage signal coverage Real-time channel and power control Accurate distance measurements A site survey only captures one moment in time

Innovation Scaling Real-Time Location and Asset Tracking Cisco Wireless Location Appliance Available Now Real-time location simultaneous tracking for thousands of 802.11 clients (clients, tags, phone) Historical trending of location API for integration with 3rd party applications (e.g., Pango for hospital asset tracking) Integrated with WCS application

Cisco Wireless Location Appliance High-resolution location software Integrated into the company’s award-winning Enterprise WLAN platform Uses advanced RF fingerprinting technology that is accurate to within a few meters. Location appliance Enables thousands of clients to be tracked simultaneously in real-time. Application Programming Interfaces (APIs) Enable the Cisco system to be tied in with external software applications E.g., enterprise resource planning (ERP) tools, scheduling and workflow software, and emergency 911 (e911) systems. Active 802.11 RFID transceiver 3-year battery Match-box sized “tags” Active beacons ensure anytime/anywhere tracking
