BANDS & CHANNELS

© 2011 Xirrus, Inc. All Rights Reserved.

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


CLIENT DEVICES

• Clients - The Weakest Link• Client Growth Drivers

• 1 to 1 initiative in classroom• Users are carrying 3x number of devices• Students Bring Your Own Device (BYOD)• New devices are engineered as Wi-Fi only

• Campus & Classroom IT• Smart whiteboards• Video / Surveillance• Projectors

Laptops Tablets Surveillance Audio Phone Audio Printers

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?


• 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

12


DEVICE MONITORING & CONTROL (MDM)

• Identify station type and class, e.g. tablet, phone, Blackberry, iPad, etc.

• Classify and manage devise based on this information


AGENDA



• Summary



THE LEADER IN HIGH PERFORMANCE WIRELESS

Traditional wireless network deployments are failing in the face of an onslaught of devices and application usage

Dense RadiosXirrus has a unique platform and architectural advantage

The XR Wireless Array is an industry first: a truly modular wireless switch

Directional Antennae

Virtualized Controllers


XIRRUS WIRELESS ARRAY

• Greatest Device density– 100’s of Wi-Fi devices per Array

• Highest capacity– Multi-gigabit capacity per Array

• Broadest coverage– 4X the coverage per Array

• 1st Radio Upgradeable Wireless Platform– Scale by adding radios to Array platform– Scale without adding Arrays to network

• 1st Software Upgradeable Performance– Upgrade radios from 300Mbps to

450Mbps• 1st Multi-State Radio Platform

– 2.4GHz and 5GHz capable on every radio• 1st 802.11ac-ready Product

– Modular platform supports new wireless technologies

• Extensible to other wireless technologies

450Mbps 11n300Mbps 11n 11ac/11ad/Other
