  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Wireless Body Area Networks] Date Submitted: [7 November, 2003] Source: [Julien Ryckaert] Company [IMEC] Address [Kapeldreef 75 B-3001 Leuven Belgium] Voice:[+32 16 28 83 44], FAX: [+32 16 22 94 00], E-Mail:[ryckj@imec.be] Re: [This document is a response to a Call For Application from theIEEE P802.15 ALT PHY Study Group] Abstract: [This document presents Wireless Body Area Network as an application example for the IEEE P802.15 ALT PHY ] Purpose: [Application requirements for the IEEE P802.15.SG4a Call For Applications] Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15. Julien Ryckaert / Bart Van Poucke, IMEC

  3. EEG POTS Vision Hearing positioning ECG Blood Pressure Toxins Network glucose DNA protein Cellular Implants WLAN Wireless Body Area Network WBAN Julien Ryckaert / Bart Van Poucke, IMEC

  4. WBAN Hospital computer WLAN Medical Applications (ex: Wireless EEG) • Monitoring : (e.g. epilepsy or sleep) • Early warning system: (recognize and warn patient of upcoming seizure) • 24 channels • 12 bit resolution per channel • 256Hz sampling rate per channel • Raw data rate: 24x12x256 = 74kbits/s (data rate could be reduced by pre-processing in the sensor) Other related applications: ECG, EMG, … Julien Ryckaert / Bart Van Poucke, IMEC

  5. Fitness Applications (ex: Wireless Oximeter) 2 channels 8 bit resolution per channel 10Hz sampling rate per channel  Raw data rate: 2x8x10 = 160bits/s Other related applications: heart beat monitoring, … Julien Ryckaert / Bart Van Poucke, IMEC

  6. BAN as an anticipated application This application fits in one of the anticipated applications defined for IEEE 802.15.4a: “Healthcare applications, e.g. remote sensors, healthcare monitoring, locating assets/staff, workplace safety” Julien Ryckaert / Bart Van Poucke, IMEC

  7. Application characteristics • Low data rates  0.1-100 kbps • Generic sensors  Scalability of the data rate • Low power consumption  ~1mW active • Low duty cycle  ~10uW average power consumption (~1% duty) • Short range  ~1m • Small size  SoC • Safety  Medical data’s Julien Ryckaert / Bart Van Poucke, IMEC

  8. Conclusion: Need for a new wireless Standard! • No standard meets the requirements for wireless communication at ultra-low power for low and scalable data rate in short-range. • New approach for the channel modeling is required • Optimization for ultra-low power rather than for high data rate • Review of the tradeoffs • New standard required Julien Ryckaert / Bart Van Poucke, IMEC
