Two frequency bands used in Wi-Fi (27 channels)•2.4GHz – used by 802.11b/g/n clients
•3 non-overlapping channels•Limited bandwidth, prone to interference
•5GHz – used by 802.11a/n clients•24 non-overlapping channels (differs by geo region)•8X the bandwidth, Less potential for interference
2.4GHz 5GHz

THE BYOD INVASION

WIRELESS NETWORK PERFORMANCE
What happens if you do nothing?
• As device density and traffic goes up, so will complaints
• Wireless networks that ran fine all of a sudden do not work
10
As Density/Usage Increases…
The Network Deteriorates
Works Does Not Work?
11© 2011 XIRRUS :: All Rights Reserved
• Traditional approach Deploy more equipment …and more cables …and more switch ports …and re-tune the RF
• Better approach Deploy higher capacity equipment More radios per AP No more cables or switch ports Add radios to chassis to grow capacity
11
WIRELESS NETWORK CAPACITY EXPANSION

DESIGN FOR PERFORMANCE
• Wireless networks must be designed for tablets/smartphones
Spotty/hot spot coverage insufficient
• Signal must be solid in all areas –67dBm minimum Live site surveys
• Full coverage for both Wi-Fi bands 2.4GHz as LCD 5GHz for most tablets & BEST performance

DEVICE MONITORING & CONTROL (MDM)
• Identify station type and class, e.g. tablet, phone, Blackberry, iPad, etc.
• Classify and manage devise based on this information
