How Broadband Wireless Is Applied To Education
•Two implementation models-Campus wide deployment
•Similar to current WiFi deployments, but with a single or few BS’s
•Likely applicable to large campuses-Wide Area coverage
•Colleges/schools covered by ubiquitous coverage of town or city
•Initially part of a community drive for broadband coverage
RR
®®
Example: Houston Co., GA drive for WiMAX Deployment
•Declaration: “Want GA to be the first state to be 100% covered by WiMAX” – GA Governor Sunny Perdue
•Community recognizes Digital Divide, and aggressively moves to close gap.
•Enables community-based applications-Safety-Healthcare-Intelligent transportation-Education
RR
®®
Example: Houston Co., GA drive for WiMAX Deployment
•Focus on education for broadband connectivity
•Pilot project driven by Mike Hall, State Superintendent for IT-4 base stations-Coverage area ~ 250 sq mi, entire county-Estimated cost ~$750K-Intel, Siemens, Alvarion, Bell South
•Education applications applications-Anywhere, anytime learning-Broadband connectivity to all schools-Intelligent transportation tracking of buses-Improve student computer utilization and expertise
RR
®®
Conclusions Conclusions • Major market growth for BWA remains ahead.• Emerging networks will support fixed access,
portable, and mobile services • Standardization leads to interoperability, integration,
and globalization• Campus based WiMAX networks can be a effective
compliment to IT and wireless strategies for education in 12-36 months.
• Successful business cases and community advocacy will drive wide spread adoption of WiMAX BWA.
