Abstract: As the use of wireless networks has grown, so has the need for intrusive / semi-invasive electrical equipment, which has resulted in the growth of Wireless Body Area Networks (WBAN). Underlying health surveillance is provided by WBAN to a client without interfering with regular activities. Because of their ability to track subjects in real time and continuously in various fields, such as tele-health, culture, sports, or weapons training, wireless body area networks (WBANs) are currently gaining popularity. They have particular advantages for the detection and treatment of chronic illnesses. Wireless Body Area Network (WBAN) is a low-power, ultra-short-range wireless technology. There have been various developments that have been successful in satisfying the special needs of WBAN patients for high quality service while promoting WBAN programmes including remote access, biofeedback, and dialysis Choosing the latest technology for a healthcare application is a difficult task due to the large number of tools accessible. Wireless Body Area Network (WBAN) developments, challenges, and design are all covered in detail in this article, as are a variety of WBAN applications. In a WBAN, the sensors, for example, measure the heart rate, the body temperature, or take a lengthier ECG as proof of good cardiac health.. After employing a WBAN, the patient is more mobile and no longer requires hospitalization. In this paper, the theoretical basis of WBANs is addressed.
