  • Nexus One: 1 GHz Snapdragon processor from Qualcomm, about 2100 MIPS 3GS is underclocked at 600 MHz, Samsung part can go to 867 MHz
  • Transcript

    • 1. The Future of Mobile Eric Brewer BEARS February 11, 2010 UC Berkeley, BEARS 2010
    • 2. Most Successful Technology Ever
      • 3-4B cellphone users worldwide
        • Vastly outpaces TV, PCs,
      • 1.13 billion phones sold in 2009
        • 36 per second
        • Versus 15 billion shoes per year
        • Versus 0.3 billion PCs
      • 174M were smart phones
        • 15% (up from 12.8% in 2008)
        • Smart phones will pass PCs in the near future
      UC Berkeley, BEARS 2010
    • 3. What’s in an iPhone? UC Berkeley, BEARS 2010
    • 4. What’s in an iPhone (3GS)
      • 600 MHz ARM processor
        • About 1200 MIPS for 300mW
        • 256MB ram, 16 GB flash
        • Roughly a 1999 Pentium III ~ 1350 MIPS for 37W
      • PowerVR graphics core
        • 7M triangles/sec, 250M pixels/sec
      • Mac OS X
        • same as Mac, iPad, iPod Touch
      • Sensors:
        • Camera, mic, GPS, compass, proximity, ambient light, ambient noise, 3D accelerometer, touchscreen, temperature
      • WiFi, GSM, Bluetooth, USB
      UC Berkeley, BEARS 2010
    • 5. What’s in an iPhone? (3GS) UC Berkeley, BEARS 2010
    • 6. Supercomputer
      • “ Access is the Killer App”
        • Access to the cloud >> any device
      • Cellphones are pocket supercomputers
        • Every search
        • Image recognition, object recognition:
          • Red laser
          • Google Goggles
        • Sound recognition: dictation, translation… Shazam
      UC Berkeley, BEARS 2010
    • 7. Replace the PC?
      • Cellphone accessories:
        • Big screen (~200M sold per year)
          • … with wireless access (Wireless USB coming)
        • Keyboard
          • Or just use voice + supercomputer?
        • Extra processing and disk space?
          • Maybe…. Or just use the cloud
          • Likely want local graphics acceleration
          • PC as a cellphone accessory
      • My bet: cellphone wins… maybe it already has
      UC Berkeley, BEARS 2010
    • 8. Developing Regions
      • Cellphones are everywhere
      • Many advantages:
        • Small, portable, with self-contained power
        • Voice works for all languages (but not text)
        • Easy to use, culturally accepted
      • +10% mobile penetration => GDP up 0.8%
        • Causal, not just correlation
        • Greatest development project ever?
      • PCs may not ever get great penetration
      UC Berkeley, BEARS 2010
    • 9. Urban vs. Rural
      • Value of the cellphone limited by coverage
        • Even more true with the Cloud
      • Cellular is an urban phenomenon
        • Rural areas generally left out
        • … basestation costs limit rural deployment
      • This is the real “digital divide”
        • Not between nations
        • … but between urban and rural (even in the US)
      UC Berkeley, BEARS 2010
    • 10. CellScope: Cellphone Microscope
      • Cellphone camera + big lens = microscope
      • Diagnosis:
        • Image recognition on the phone?
        • … in the cloud?
        • … by a remote expert?
      • Clinical quality:
        • Malaria,
        • TB already verified as detectable
      UC Berkeley, BEARS 2010 Dan Fletcher UC Berkeley
    • 11. SmartPhone Diagnostic Device
      • Idea: collection of very simple sensors that connect to the audio jack
        • Easy: heart rate, respiratory rate, temperature
        • Medium: blood oxygen, ECG
        • Hard: blood pressure
      • Goal: much cheaper, easy to use diagnostic device
        • Phone converts raw data into readings
        • Can also forward raw data over GSM
      UC Berkeley, BEARS 2010
    • 12. Conclusion
      • Smart phones =
        • PC + sensors + connectivity + portability
      • Access is the killer app
        • The real win is phone+Cloud
      • Cellphones are transforming development
        • Driving increased quality of life for the poor
        • The first high-tech solution to cross over
      • Rural access must be a priority
      UC Berkeley, BEARS 2010
    • 13. Backup UC Berkeley, BEARS 2010
