13 th GENI Engineering Conference GENI BUILDING WIMAX

13 th GENI Engineering Conference GENI: BUILDING WIMAX, BUT WHAT ABOUT LTE? Patrick J. Gossman, Ph. D. Deputy CIO, Wayne State University Executive Director, Community Telecommunications Network March 15, 2012

LTE, Where the World is Going Why? Better performance, mobility…. N=1, handoff All major carriers globally are going LTE Clearwire migrating from Wi. Max to LTE Wi. Max will be gone in U. S. by 2015? Wi. Max development falling off? Wi. Max equipment to become less available? 2

LTE Issues to Resolve CPE – Available? Open? Base stations – Available? Open? Costs? Software development? Support? What spectrum? 2. 5 GHz, 3. 65 GHz, 600 MHz (TV Whitespace), other? But many of the same questions for Wi. Max? 3

With all the problems, why consider LTE? It’s where the world is going… development is here, deployment is here, new equip here Government support - Spectral efficiency is big driver (National Broadband Plan) Industry support - Companies as potential partners providing equipment, spectrum, pipeline for students Lots of areas to explore (EICIC, Co. MP) LTE, LTE-Advanced, TD vs. FDD 4

Where does this leave us? Wireless demand has already exceeded capacity in some areas and many forecast major shortages as early as next year More spectrum is one part of the solution Better use of spectrum is another Solution: Form a new collaborative Education (universities) Government (NSF GENI) and Industry (LTE manufacturers and carriers) 5

Clearwire Wi. Max Deployment Clearwire to provide free service from three sites. Rings show 1 mile and 2 mile radius. Matrix Human Services Focus: HOPE 4 C – The Family Place Estimated Coverage Wayne State University Indoor Outdoor Low Signal The coverage is modeled. Actual results will vary depending upon surrounding structures, building type and location. Thus, some areas, even if marked in green, will not receive coverage. Connection speeds may fall with distance from antennae. 7

5057 Woodward Avenue Wi. Max Site DETS 007 has three, 120 degree sector antennae, two of which are visible from the southwest. 8
