Patient Monitoring through BAN
Increasing population and the rising costs of health care
have triggered the introduction of novel technology-driven
enhancements to current health care practices.
advances in electronics have enabled the
development of small and intelligent (bio-) medical
sensors which can be worn on or implanted in the human
Thus introduced Wireless Body Area Network (WBAN).
4. What is BAN…???
Definition by IEEE: “A communication standard optimized for
low power devices for their operation on, in or around the
human body (but not limited to humans) to serve a variety of
applications including medical, consumer electronics or
personal entertainment and other.”
Broad range of possible devices
Connect everything you carry on you and with you
Offer “Connected User” experience

11. Positioning of WBAN
The communication in WBAN is divided into:
2. Extra-body Communication

13. Applications of BAN
WBAN applications are divided into 3 categories as-
Figure: WBAN Applications
14. 1. Health Care
Current healthcare applications of wireless sensor
networks target heart problems cancer, asthma,
glucose level monitoring, stress monitoring etc.
Smart biosensors will open up new opportunities for
continuous monitoring of patients.

18. Advantages of BAN
Used for detection of chronic diseases.
Used in military for security purposes.
Assists seamless communication between individual
19. Future Scope
The future market of WBAN is growing rapidly in the field
of medical as well as in the entertainment industry.
We believe that WBAN systems will allow a dramatic shift
in the way people think about and manage their health.
This provide more proactive preventive healthcare that will
not only improve the quality of life, but will also reduce
A WBAN is expected to be a very useful technology
with potential to offer a wide range of benefits to
patients, medical personnel and society through
continuous monitoring and early detection of possible
The current technological evolutions will bring us
closer to a fully operational WBAN that acts as an
enabler for improving the Quality of Life.
