3. Introduction
 Increasing population and the rising costs of health care
have triggered the introduction of novel technology-driven
enhancements to current health care practices.
 Recent
advances in electronics have enabled the
development of small and intelligent (bio-) medical
sensors which can be worn on or implanted in the human
body.
 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

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
healthcare costs.
