LTE, Where the World is Going  Why? Better performance, mobility….  N=1, handoff  All major carriers globally are going LTE  Clearwire migrating from WiMax to LTE  WiMax will be gone in U.S. by 2015?  WiMax development falling off?  WiMax 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 WiMax? 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, CoMP)  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

7 Matrix Human Services Clearwire WiMax Deployment 4C – The Family Place Outdoor Indoor Low Signal Clearwire to provide free service from three sites. Rings show 1 mile and 2 mile radius. Wayne State University Focus: HOPE Estimated Coverage 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.

Woodward Avenue WiMax Site DETS007 has three, 120 degree sector antennae, two of which are visible from the southwest.
