  1. Grand Challenges in Wireless Steve Gillig Director, Communication Technologies Research Labs Motorola Labs

  2. SDR and Cognitive Radio Vision Imagine A Mobile Communication System … … With devices capable of multi-band, multi-mode operation and easily re-configured via software and upgradeable via a scalable architecture, … Software Defined Radio … That securely repairs software bugs, releases software updates, and provides real time like-you-were-there customer care over-the-air, … Over-The-Air Device Management … Where devices are aware of other nearby devices and networks, and capable of changing frequency bands and modes of operation to find and secure or lease unused spectrum, avoid interference, and improve coverage. Cognitive Radio

  5. 4Gx – 4G Experimental System Motorola Tower • Suburban Schaumburg Tribune Tower Downtown Chicago • Base antennas 11th and 35th floors • Completed 4G field experiments • with handheld devices • both urban and suburban • Single antenna with various modulations: 20-80Mbps • 2x2 MIMO @ 300Mbps (post-processing, ideal channel knowledge) Pedestrian Measurements

  6. Suburban vs. Urban Findings • Delay Spread • Suburban location experienced more RMS delay spread than the urban 11th Floor Tx • Urban 35th Floor Tx experienced more RMS delay spread than the 11th Floor Tx • Spatial Conditioning (2x2 MIMO Reciprocal Condition Number) • 11th floor Chicago > 35th floor Chicago >> Schaumburg • Rooftop > Handheld

  7. Seamless Mobility Opportunity WLAN vs 3G/4G: Domination or Co-existence?

  9. Seamless Mobility is not just continuity of bits… it’s continuity of experience

  10. “I’m a die hard Boilermaker football fan. I watch the pre-game show on HDTV… Walking to the stadium, my excitement builds as the experience follows me on my phone … In the stadium, I see a great run and get statistics on the running back ... Of course, I order clips of Purdue’s win over Ohio State in the final 10 seconds … They’re available anytime … When I’m with friends in the Union … When I’d rather see a curl on a football field than an H-field.”

  11. “I like to share music videos with my friends. My PC’s big screen really makes the latest John Mayer MV come alive in my room … My friends call, so I pause it and get ready to meet them at Starbucks … I resume the MV on my phone while on the walk there … Sipping Cappuccinos, we take turns sharing our favorite MVs on each others phones … Sharing with my friends is cool; I even share some clips of John Mayer I took with my phone at his last concert.”
