Hello, everyone!
Today, I would like to continue to share with you the medical application scenarios on WBAN (Wireless Body Area Network) technology.
The system uses an RF (Radio Frequency) transceiver that was created specifically for use in in-body communication systems. The device creates a medical sensor network of implantable devices by combining the new medical band MICS with the 433 MHz ISM band.
As the MICS band grows in popularity, more of these miniaturized low power RF transceivers should be designed in the future for usage in medical sensor networks. Wearable, wireless (no wire connections), and easy to remove and install sensor nodes will result from the successful implementation of a comprehensive WBAN system, giving patients more mobility and freedom.
A WBAN should operate in the same frequency bands as other network devices and coexist with them. As a result, ensuring an interference-free, dependable wireless link from sensors, which combines and interacts with existing wireless technologies to establish a heterogeneous networking environment, is critical.

One of the most common uses for a WBAN is in the medical field, where the health of a significant number of patients may be regularly tracked. Figure 1 depicts a WBAN-based monitoring scenario that could be used in a hospital setting. The illustration depicts multiple rooms on a single hospital level.
As can be observed, numerous controlled units (CCUs) are necessary for a large-scale deployment of WBANs in order to organize the collecting of medical data from patients' bodies. The presence of many CCUs is also advantageous for patient mobility within hospitals. In fact, monitoring a large number of physiological signals from a significant group of patients poses some software and hardware design issues.
The following are some of the challenges:
Ensuring reliable connection by avoiding signal collisions between several patients and interference from other external wireless devices
Keeping costs low and power consumption low
Giving patients the option to relocate at any moment.
I will continue to share on this article in the following post.
