Wi-Fi: Vision

“Wi-Fi will overtake Wired as the primary

network connection in the Enterprise as

evidenced by the wave of new devices being

introduced without a Wired connectivity option”

How many Wi-Fi devices do you use today?

Wi-Fi: Reality

“Within 24 months, 60-80% of Enterprise users will rely

upon recently mobilized applications. They will use

3+ wireless devices over a cloud-based infrastructure

to access these applications.”


Wi-Fi: Critical Success Factors - Applied

3,000+ Software Developers in a conference hall for 5 days getting

trained and using new tools from the world’s largest software

company using a Wi-Fi network instead of a Wired network….

A Battalion of U.S. Marines deployed under the harshest conditions

for weeks at a time with the need to monitor and communicate

instantly with their command structure using a Wi-Fi network instead

of a Wired network…


Wi-Fi: Critical Success Factors - Applied

2,000+ Engineers sitting in a conference hall for several weeks

crunching data to determine how to allocate the radio spectrum

around the globe using a Wi-Fi network instead of a Wired network…

One of the largest and busiest seaports in the world that connected

all of their dockside applications and workers using Wi-Fi instead of

a Wired network…


Market: K-12 Education

The Problem:

User-Density and Performance are the biggest issues

Coverage, Security and Management are also important

Many schools have Wi-Fi today, but can’t support the current 1:1 initiatives

Schools are overrun with Wi-Fi enabled devices (iPhones, Android, etc.)

The Solution:

Xirrus provides greater user performance under heavy loads

Selected by Pearson Digital for “Wireless Waterford” & “Wireless Success Maker”

Xirrus supports unsurpassed user densities in classrooms and lecture halls

Xirrus offer better coverage (4X) with 75% fewer devices, less cable runs

Mostly XN4s / XN8s for classrooms and XN12 / XN16s for high-density areas

Libraries, auditoriums, gyms & stadiums


Case Studies: K-12 Education

Plano ISD

Location: Dallas, TX area

Competition: Cisco lead to technical bake-off

55,000 students, 7,000 faculty/staff, 80 campus locations

1,019 Arrays, 6,623 radios

Forsyth County Schools

Location: Atlanta, GA area

Competition: Aruba lead to technical bake-off

36,000 students, 5,000 faculty/staff, 40 campus locations

662 Arrays, 5,296 radios

Market: Higher Education

The Problem:

Most have Wi-Fi .11b/g, upgrading to .11a/g/n to handle demand

User Density and Performance are the biggest issues

Coverage, Security and Management are also important

Student dorm rooms are saturated with Wi-Fi enabled devices (PS3, WII, Xbox)

Many students carry 2-3 Wi-Fi devices (laptop, iPhone, &iPad, PSP)

The Solution:

Xirrus provides greater security and performance under heavy loads

Xirrus supports increased user densities in classrooms and lecture halls

Xirrus offers better coverage (4X) with 75% fewer devices, less cable runs

Mostly XN8s for classrooms and XN16s / XN12s for high-density areas

Libraries, auditoriums, gyms & stadiums


Case Studies: Higher Education

Pepperdine University

Location: Malibu, CA

Aruba failed installation, Xirrus replaced due to cost overruns

8,300 students, 1,000 faculty, campus locations & dorms


Carnegie Mellon University

Location: Pittsburgh , PA

Competition: Cisco, Aruba technical bake-off

14,000 students, 4,000 faculty/staff, 144-acre campus





Market: Healthcare

The Problem:

Security (HIPPA) and Network Redundancy are the key concerns

Roaming/Mobility, Performance and Management are also important

Medical Wi-Fi Device Density is increasing dramatically

Tablets, VoIP Phones, Monitors, infusion pumps, and scanners

Operating rooms are becoming dense Wi-Fi environments

Many Hospitals and Assisted Living also want to offer Patient & Guest Access

Security, Multiple VLANs and Web Page Redirect is important

The Solution:

Xirrus improves Regulatory Compliance (HIPPA) Security & 99.999% Reliability

Xirrus improves Quality of Care and increased user density for medical devices

Xirrus provides Greater Performance under heavy loads (ie, Emergency Room)

Xirrus provides Increased Coverage with fewer devices, less cable runs

Xirrus provides Better Patient & Staff Safety via Location Tracking


Case Studies: Healthcare

Great Plains Health Alliance

Location: State of Kansas

Competition: Cisco, Aruba

20 Hospitals, 14 Clinics, and 5 offices

150 Arrays, 900 radios

Alder Hey Children's Hospital

Location: Liverpool, England

Centre of Excellence for treating for child cancer, heart, spinal and brain disease

Competition: Cisco

Employs over 2,700 staff, 600 students, 4 Hospitals

Treats 200,000+ children each year





Market: Events

The Problem:

User-Density and User-Experience are the biggest concerns

Coverage, Security and Management, Guest Access are also important

Some Convention Centers and Events have Wi-Fi today, but can’t support the

density

Smart Phones Create Flash Storms (iPhone, iPod Touch, Android, Blackberry, etc.)

POS and Ticket Scanners become unreliable and unstable = lost revenue

The Solution:

Xirrus is the only vendor to support ultra-high performance applications

Xirrus supports unsurpassed user densities in convention centers, stadiums

Xirrus offers better coverage (4X) with 75-90% fewer devices, less cable runs


Microsoft Corporation Location: Seattle, WA

Xirrus selected to deliver Ultra-High Density Wi-Fi

3,000 concurrent users for Developers Conference

60 Arrays, 960 radios – all 16 radio Arrays

International Telecommunications Union

Location: Geneva, Switzerland

Provide high-density Wi-Fi for 30 conference rooms and 45 offices

2,000 concurrent users in main hall

33 Arrays, 363 radios

Case Studies: Events



Wi-Fi: Conclusion

More devices… More content… More demand…

Organizations that plan for More and implement using

these Critical Success Factors will be able to:

Mobilize faster

With less effort

With reduced risk

Deliver a higher level of service

Distributed

Intelligence
