4 Changing Role of Wi-Fi in Education © 2011 Xirrus, Inc. All Rights Reserved. Wi-Fi will overtake Wired as the primary network connection as evidenced by the wave of new devices being introduced without a Wired connectivity option Trends Impacting Wi-Fi in Education: Capacity & Performance are key, coverage is a given Proliferation of Wi-Fi Devices, you cant stop them Higher bandwidth applications, will continue to grow

5 Enterprise Adoption Rate Wi-Fi: Devices Client devices are increasingly being engineered with Wi-Fi as the only network connection Desktops Laptops VoIP Phones Notebooks Wired Wi-Fi Smartphones Netbooks iPads Tablets © 2011 Xirrus, Inc. All Rights Reserved.

6 What are the Critical Success Factors? Educational Wi-Fi: Reality Within months, 60-80% of your users will rely upon mobilized applications. They will use 3+ wireless devices over a cloud-based infrastructure to access these applications.

7 Enterprise Adoption Rate Wired Wi-Fi Wi-Fi: Applications Applications are mobilizing via the cloud and will increasingly be accessed over Wi-Fi Mainframe Data-centric Client / Server Data, Voice & Video Client / Server Data & Voice over Wi-Fi Data, Voice & Video over Wi-Fi Data over Wi-Fi Cloud-based Data, Voice & Video © 2011 Xirrus, Inc.

10 Taking advantage of Wired Lessons Learned is a best practice To Address Wi-Fi Performance Needs… Best Practice: Since the late 70s Ethernet has continued to evolve, providing higher performance via a distributed architecture, higher density devices and leveraging all available media. It only makes sense for Wi-Fi to mirror these practices. Distributed Intelligence Forwarding & Filtering at Edge No Single Point of Failure No Processing choke point Dense, Multi-state Ports Intelligent connectivity Auto detect speed/band/channel Supports client migration Distributed Intelligence /100/1000 Mbps 11/54/300/450 Mbps Base-T IEEE n 4 pairs provide 1Gbps Media fully leveraged 3 channels of 2.4GHz = 450 Mbps 24 channels of 5GHz = 3.6 Gbps spectrum fully leveraged Enterprise Best Practice Leverages all available medium Improve B/W across all medium Sufficient for network needs

To Address Wi-Fi Security Needs… Doing your security due diligence is a best practice Authentication Machine and/or User 802.1x/MAC/WPR Separate User Classes by SSID Best Practice: Whether called due diligence of just a best practice all enterprise networks providing client connectivity to critical applications require the ability to verify users, protect the communication channel and monitor the RF environment Encryption WEP, WPA, WPA2 Distributed Processing Separate User Classes by SSID IDS/IPS 24/7 monitoring/mitigation Integrated solution RF analyzer to monitor spectrum

12 To Address Wi-Fi Resiliency Needs… Confidential Information. © 2010 Xirrus, In. All Rights Reserved. Page 12 Best Practice: Having end to end redundancy is always an Enterprise connectivity best practice. Wired solutions fell short at the edge and traditional Wi-Fi falls short at the core. Look for a solution offering reliability at all points in your network. Edge Multiple Radios/Channels Load balancing across radios Band /Mode Steering Access Level Distributed intelligence Auto Cell Recovery Auto Channel Services Core Redundant wired uplinks Redundant WDS uplinks 802.3ad link load balancing System level availability is a best practice

13 To Address Wi-Fi Management Needs… Confidential Information. © 2010 Xirrus, In. All Rights Reserved. Page 13 Best Practice: Management applications, no matter wired or wireless must have the ability to manage, monitor all networked devices and provide detailed reporting and statistical data for each device, or the network as a whole. Wireless adds the requirement to also monitor RF environment for interference or potential threats Device Specific Provisioning Monitoring / alerting Upgrading Reporting Enterprise Wide Multiple SSID/User Groups Traffic limiting Load balancing Reporting RF Environment Threat Monitoring Coverage Assurance Interference Monitoring Reporting System level management is a best practice

14 To Address Wi-Fi Site Survey Needs… Confidential Information. © 2010 Xirrus, In. All Rights Reserved. Page 14 Best Practice: At best, predictive surveys are a estimate, live site surveys take actual measurements using the same devices that will be deployed. This is the only way to guarantee coverage, # of devices and most importantly cost. Coverage Verification Active Measurements Verifies real RF propagation Visually inspect site RF Analysis RF Interference Check Neighboring Wi-Fi Potential Threats Guarantee Actual Product capabilities Coverage/Performance Product Numbers and cost Live site surveys are a best practice

15 Performance Security Resiliency Management SiteSurvey Final Thoughts: Its Math, Not Marketing © 2011 Xirrus, Inc. All Rights Reserved. More Radios, Separate Channels = More Bandwidth Channel Planning is key 27 Available Wi-Fi Channels (3 in 2.4GHz, 24 in 5GHz) Avoid Co-Channel & Adjacent Channel Interference (spectral mask) Lowering radio power is seldom the answer Use Cognitive Systems ( Multi-State, Multi-Mode, Multi-Channel …) Limit the number of SSIDs you define Clients, Clients, Clients, …. Purchase multi-band devices Understand signal level requirements Consider return path signal levels

16 Wi-Fi: What is your plan? NoQuestionYes X Do you need to deploy Wi-Fi as a primary network connection somewhere on your campus during the next 2 years? X Do you need a Wi-Fi solution that will support all your educational and business applications, not just basic Hot Spot services? X Do you need a Wi-Fi solution that can support major traffic spikes (flashtraffic) throughout your campus as students move and congregate? X Do you need a Wi-Fi solution that can be deployed with a minimum of classroom disruption and operate with % reliability? X Do you want a guarantee for the Wi-Fi solution you purchase for one or all of the following: performance, capacity, or the cost of implementation? © 2011 Xirrus, Inc. All Rights Reserved.
