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.
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
