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.

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 _at_ 300Mbps (post-processing, ideal
  channel knowledge)

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 gt 35th floor Chicago gtgt
  Schaumburg
• Rooftop gt Handheld

Im 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 Purdues win over
Ohio State in the final 10 seconds Theyre
available anytime
When Im with friends in the Union When Id
rather see a curl on a football field than an
H-field.

I like to share music videos with my friends. My
PCs 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.

  sensitive driven by affordable, available
  broadband
• Applications explode digitization of everything
  at the edge of the network
• Privacy, safety and security critical for
  content that is purchased and created
• Full mobility across heterogeneous networks
• Always on, always here sessions that cross
  networks and devices, seamlessly
