Introduction• BAN is about providing a unified and scalable (in terms of data
rate, power, number and density of nodes) solution for connectivity in, on and around the body– Enables the convergence of sensors/actuators, wireless
communication and healthcare/consumer devices– Towards the connected consumer experience
• A BAN standard must:– Provide the pathway to achieve the required scalability and low
power goals– Provide the necessary QoS, coexistence, security, network
management, SAR compliance and reliability needed by the envisioned applications
• A BAN standard must address healthcare applications– Many upcoming applications from both professional and consumer
arenas• “Wireless applications that improve the lives and quality of service to
cardiac patients represent only the first wave in what will be an ever-exploding field”1
– Consumer electronic (CE) applications should also be considered1 N. Ansari et al, “Wireless technology advances and challenges for telemedicine,” IEEE Comm. Magazine, vol. 44, no. 4, April 2006.

BAN Applications• Convergence of healthcare and CE
applications towards the connected consumer experience
• Healthcare– Implantable medical devices
• Cancer tracking, cardiac pacemakers / defibrillators, neurostimulators, drug pumps, glucose sensor, etc.
– Swallowable• Pills for drug delivery and imaging
– Wearable sensors• EEG, ECG, blood pressure, body
temperature, …– Hearing aids– Wellness / Fitness sensors– Baby care
• CE– Wearable audio & Video stream– Remote control & I/O devices
• E.g., Imaging

BAN Applications
Implanted Body-worn

Use Case: Drug Delivery
• Pill travels in the gastro-intestinal tract and is in periodic wireless communication to an external unit near the body
• Pill lifetime is between 8-72 hours
• Communication range is between 1 and 3 meters

Submission
Use Case: Drug Delivery
• Patient at home– Pill reports actions and sensor data to portable unit every few seconds or
minutes– Possibly more than one pill in the patient– Can not guarantee portable unit is within range
• Pill may store data and download when portable unit is found
• Patient in research clinic or hospital– Multiple patients on a clinical ward– Pill reports actions and sensor data– Possible central external unit talking to and commending several pills
• Data rate– Generally low: status and simple sensor (e.g., pH) measurements taken on
the order of every minute– Exception: use of an image sensor where images are taken and transmitted
• Commercial products exist with data rates as high as 800 Kbps

Use Case: Deep Brain Stimulation (DBS)
• A treatment of neurological diseases and conditions by an implanted brain pacemaker that stimulates different regions of the brain with electrical impulses

Submission
Use Case: Deep Brain Stimulation (DBS)
• The IPG needs to– Communicate wirelessly
with an external unit– Communicate wirelessly
with an electrode controlling unit
• Requirements– Data rate between 128
Kbps and 320 Kbps– BER < 10-10
– Stand-by power < 0.1 mW– Lifetime between 3 to 5
years– Range less than 3m

Use Case: Tumor Growth, Treatment• Based on sensed data by
implanted devices, doctors can change a patient’s treatment or even recalibrate the implanted device1
• Doctors can decide when it is the right time to take the next step in a patient’s treatment
Use Case: Glucose Level Monitor• In patients with diabetes, a
body-worn glucose monitor analyzes the level of glucose in the body
• If the glucose level surpasses a desirable value, the glucose monitor informs the patient and, if appropriate, communicates with the implanted insulin pump to release the right amount of insulin
• Data rate in the order of 1 Kbps

Use Case: Healthcare and CE (1)• While doing exercise, one
could use the same personal device (e.g., MP3 player, cellular phone, etc.) to:– Stream music to a wireless
headset– Receive and display sensing
data such as heart rate, glucose level, body temperature, speed, distance, etc.
• Information sensed can be used to set the pace for the rider
• If an abnormal event is detected, an alarm is sent from the personal device to the wireless headset

Use Case: Healthcare and CE (2)• User carries a mobile device (e.g.,
cellular phone) which controls and displays a number of features:
– Sensors: body temperature, glucose level, heart rate, etc.
– Streaming to wireless headset– Remote control (e.g., the PDA,
personal CD player, etc.)
• Mobile device is also used as a gateway to send remote patient monitoring data to a central database where it can be accessed by the patient’s physician
• Scalable data rate (up to 10Mbps) and power consumption (up to 40mW) requirements
