Hello, everyone!
Today, I would like to continue on the implementation of WBAN (Wireless Body Area Network) technology.
The network between sensors and CCUs, a network among CCUs and base stations, and finally, a network among base stations at healthcare institutions. The distance between the first and second wireless links is generally less than 10 meters.
The second link is designed to cover a distance of even more than 100 meters. The internet is used to distribute data to remote locations.
A CCU could be utilized in a health clinic for a single patient or individually in a patient's home. If a CCU box is shared by multiple patients, the CCU can be tethered to a local PC in the room or it can transfer data with another remote CCU box connected to a local PC through another wireless link utilizing the WMTS (600 MHs) link, as shown in the below Figure 1.
Figure 1. In a medical center, a multi-patient monitoring scenario is depicted, with one room and one level representing one room and one floor, respectively.
The below Figure 2 shows a multi-hopping wireless medical network (WBAN) that collects information from the sensors mounted on or in the body using the MICS band. In a remote wireless communication link, the WMTS band is employed in the intermediate node.

The data is sent to remote locations via the medical center's existing local area network or the internet. Unlike the other healthcare sensor networks (which often operate in the 2.4 GHz ISM band), we primarily employ medical standards in frequency bands that are typically reserved for medical applications.
These frequency bands are available globally and can be used to monitor numerous patients remotely at the same time. The MICS band, which is analogous to the UWB, has a low emission power of 25µW. Medical sensor nodes will benefit from the decreased energy usage capability.
The system implements hardware and software designs to provide a multi-patient monitoring system that can send data to a distant computer via a network or the internet.
To provide a multi-patient monitoring facility, a media access layer (MAC) has been installed on the created hardware.
