EBS / WiMAX 101 Bill Johnson

This overview provides a detailed look at Educational Broadband Services (EBS) and WiMAX technologies, particularly in educational environments. It discusses the significant number of licenses held by schools and highlights a case study where a college acquired an IT wireless license without the CIO's knowledge. Additionally, the text clarifies important terminologies like ITFS, MMDS, and GSA, and outlines the potential value of licenses. Guidance for uninformed licensees on leases and the implications for mobile technology access in education is also included.

  2. Overview • Describe EBS environment • Comment on a large number of licenses held by schools across the region. • Explain how a college got an IT Wireless license without the knowledge of the CIO • Provide the otherwise uninformed licensee about background, value and offer some guidance on leases.

  3. Glossary • ITFS -old nomenclature implied “Instruction” “Televised” • TV station – TV set technology • Education ITFS • Entertainment MMDS • EBS -new nomenclature implies Education and Broadband but omits Televised and Fixed. Mobile “I.T.” services are implied. • Access Point – Mobile technology • Excess Capacity Lease to MMDS operators. This could allow MMDS operators up to 33 channels of video allowing them to compete with “wired” CATV systems. • GSA; “Geographic Service Area” 35 miles in radius minus half the overlaps (split the football). • MHzPOP – Standard Unit to determine value of license

  4. 1963 ITFS - TV Broadcast Bureau (47 CFR Part 74) Shared spectrum with MMDS 6MHz channels with 6MHz Guard Bands

  5. 2008 WiMAX“Worldwide Interoperable Microwave” Wireless Bureau (47CFR Part 27). (can do 30 yr lease. Must prove services) Re Banded 15.5MHz blocks. Better for Digital Services WiMAX Forum - 2.5-2.7 GHz spectrum (802.16e) Sprint/Nextel 2.5-2.7GHz will be G4! Similar spectrum in Europe, Manufactures; Samsung Intel Motorola Nortel NextNet hundreds more

  6. Value of a License • Megahertz (roughly 2.5 Mb/sec) • GSA (Geographic Service Area) • 35 mile radius minus half of each overlap • Pop • You’ll need help getting this • Megahertz-POP; MHz X POP = “MHzPOP”. • 22.5 MHz X 100,000 Pop = 2.25 Million MHzPOP • $/MHz-Pop. Deals range from $.03 to $2.00

  7. Non-Leased Campus Deployment Users device can be served by Sprint OR Campus system Virtual Campus Calling System Possible Campus Deployment Mobile Switching Office T-1 WiMAX In-building system WiMAX Campus system Seamless roaming off-campus
