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.
