摘要
Utilizing fifth-generation (5G) sensing in the health care sector with increased capacity and massive spectrum range increases the quality of health care monitoring systems. In this paper, 5G C-band sensing operating at 4.8GHz is used to monitor a particular body motion of multiple sclerosis patients, especially the tremors and breathing patterns. The breathing pattern obtained using 5G C-band technology is compared with the invasive breathing sensor to monitor the subtle chest movements caused due to respiration. The 5G C-band has a huge spectrum from 1 to 100GHz, which enhances the capacity and performance of wireless communication by increasing the data rate from 20Gb/s to 1Tb/s. The system captures and monitors the wireless channel information of different body motions and efficiently identifies the tremors experienced since each body motion induces a unique imprint that is used for a particular purpose. Different machine learning algorithms such as support vector machine, k-nearest neighbors, and random forest are used to classify the wireless channel information data obtained for various human activities. The values obtained using different machine learning algorithms for various performance metrics such as accuracy, precision, recall, specificity, Kappa, and F-measure indicate that the proposed method can efficiently identify the particular conditions experienced by multiple sclerosis patients.
