PicoRadio Applications
The Obvious Choice -The Smart Home and Network
Appliances
5
Interacting Toys
To bring about the existence of a broad range of
plug-and-play interoperable PC-connected and
networked toys by defining common requirements on
untethered communication infrastructure between
toys and PCs that enable play nearby the PC or
anywhere in and around the home.

• Stated requirements
• Plug-and-play
• Interoperable
• Networked - preferably with pc
• HomeRF compatible

6
Industrial Building Environment Management

• Task/ambient conditioning systems allow thermal
  condition in small, localized zones (e.g.
  work-stations) to be individually controlled by
  building occupants
• Requires dense network of sensor/monitor nodes
• Wireless infrastructure provides flexibility in
  composition and topology
• Joint research proposal CBE/BSAC/BWRC

The Interactive Museum
Elploratorium is a superset of smart home and
smart office!

A Testbed for PicoRadio

• Flexible platform for experimentation in
  networking and protocol
• Projected size 3x4x2
• Multiple radio modules Proxim, Bluetooth
• Collection of sensor and monitor cards
• Available soon!

Test Bench Uses

• Pick Exploratorium exhibit to come to BWRC and
  add test benches
• Use to test MAC and Network protocols

10
Implementation Target Integrated PicoNode
11
Implementation Hardware and Software

• Mostly in TCI right now, but will transfer the
  knowledge
• Tensilica Processor, Sonics bus
• Protocol development methodology, formal
  verification
• Which tools to use and how to get to hardware and
  software

12
Joined Networking-Positioning
1 error

• Ubiquitous radio networks offer accurate
  localization with minimal overhead
• Potential to substantially reduce networking
  overhead!

13
Radios (Physical Layers)

• Looking at UWB
• Profiling sinusoidal radios
• Identify common kernels
• Pick a set of kernels that give us the
  flexibility and energy efficiency we need
• put kernels together in a Maia sort of way

14
Work with other groups

• Energy Scavenging (Paul Wright)
• BASICS group (Ramchandran)
• coding, data compression, QOS
• Ad Hoc networks working group forming
  Berkeley-wide
• Center for the Built Environment
• Smart offices, office-wide sensor networks

15
The Holy Grail Energy Scavenging
Energy Sources
Integrated micro-vibrator provides 10-100 mW of
free power (equivalent to 2340 free DSP
