Medical Applications (ex: Wireless EEG)
• Monitoring : (e.g. epilepsy or sleep)
• Early warning system: (recognize and warn patient of upcoming seizure)
Hospital computerWBAN
WLAN
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, …

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
