A Group Monitoring Wireless System for Health Care Monitoring

Body Area Network (BAN) is a sensor network technology for monitoring and logging vital signs of a person, such as cardiac frequency and blood pressure. The main goal of BAN is to make remote monitoring possible. In this paper a group monitoring approach is presented. The work differs from others because the idea is to monitor a group of patients in a hospital or clinic at the same time while having only one receiver for up to 32 people. There is no need to have a transmitter/receiver pair for each patient, making the system affordable. The solution presented also involves wireless transmission, i.e., the captured signs are transferred from the patient device to a host in a wireless fashion. Practical experiments are presented to demonstrate the feasibility of the system.
