Why Cisco is Different
Cisco designed a complete WLAN system from the
“RF in”, aimed at solving the main issues
for deploying wireless networks:
• A Complete WLAN system
Uniform WLAN policies across main office, branch offices, and remote offices
• Easy to Deploy and Operate
Best WLAN management tools on the market (from planning to operations)
Real-time RF Management
• Proven security for any enterprise environment
Wireless prevention
Real-time WLAN protection
• Best-in-class Performance
Designed for converged voice and data applications
• Eliminates the need for overlay systems (locations, IDS, etc)

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
