Motivation for Body Area Networks

• Average user carries many devices• Wide range of applications• Devices do not work as a unified system to

provide a “Connected User” experience• The portable/mobile nature of these

devices/applications requires very low power

Key Technical Issues• Power

– Low average and peak power (<< 100’s of mW)• 1’s of mW @ 1Mbps• 10’s of mW @ 10Mbps

– Duty cycling• Flexible & efficient sleep modes• Fast set-up time

– Battery life• Minimum impact to portable device battery life• Long standby times for sensors, headsets, headphones

• Scalable data rates– Low data rate sensor telemetry (10’s kbps)– Media streaming (up to 10 Mbps)

• Scalable network– Peer-to-peer network topology with no central coordinator– Automatic node detection, network configuration and service discovery– Simultaneous users and applications– Support for multicast

• Spectrum– Global unlicensed footprint– Small antenna design

Personal/Distributed UI Use Cases

• Secondary display for portable devices– Watch display:

• Incoming calls• Playlists / media info

• Secondary keypad/keyboard• Simultaneous display/UI and:

– Audio/Media streaming– Voice– Sensor data acquisition

• Control– Separate data channel for volume control

and media player controls

Sensor Use Cases – Data/Telemetry

Speed/Activity

Heart Rate

Display

• Device discovery– Programmable, proximity-based pairing– Programmable, proximity-based data transfer and

security• Multiple simultaneous sensors

– Multiple sensors/user– Multiple user in the vicinity

• Dual-mode support– “Raw” waveform (processing on receiving device)– Digitized data (processing on sensor/transmitter)

• Data acquisition reliability– Store & forward, multihop– Temporary storage on intermediate device

• Simultaneous data and audio/voice use– Independent channel management for multiple

access– Fitness application example

– Sensor data acquisition + audio playback
