1:1 Challenges Philosophies: • “… one-to-one program is to support and enhance the curriculum …” • “… one-to-one computing represents the ultimate in technology immersion…” EdTech, Focus on K-12. Nov. 10,2009 Technology: • Infrastructure enhancements • Design considerations • Equipment specifications • Data network security • Management/Visibility • Internet planning
Infrastructure Upgrades: • 802.11n places increased demands on the upstream wired network infrastructure • WLAN Controllers • Backhaul Ethernet • Insufficient Power over Ethernet (PoE) • 802.11n APs require up to twice the 12.95W delivered via 802.3af PoE • Future chipsets may be more power-efficient • Emerging 802.3at PoE standard will deliver 30W Capacity planning must be a part of any 802.11n deployment.
Previous Wired Design Considerations • Chassis based core • Individual 24-port switches at the Access layer • 1 gig uplinks to the IDF’s • 10/100 Ethernet to the classrooms • IEEE 802.3af and 802.3at Power over Ethernet (PoE)
Current Wired Design Considerations • Chassis based core • Chassis based Access layer • 10 gig uplinks to the IDF’s • 10/100/1000 Ethernet to the classrooms • IEEE 802.3af and Enhanced Power over Ethernet (PoE)
Previous Wireless Design Considerations • Design based on users per AP instead maximizing AP coverage area • Equally important is the consideration given to the logical network design. Ie. Broadcast domain.
