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?

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?

4

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

5

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)

EstimatedCoverage

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.
