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).

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 devicesConnect everything you carry on you and with

youOffer “Connected User” experience

Advantages of BANUsed for detection of chronic diseases.

Used in military for security purposes.

Assists seamless communication between individual and peoples.

Future ScopeThe 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.

04/12/2023 20

ConclusionA 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 problems.

The current technological evolutions will bring us closer to a fully operational WBAN that acts as an enabler for improving the Quality of Life.
