Medical surveillance is based on continuous monitoring of the patients vital parameters. The control of vital signs is essential in different cases. Actually, in the case of criticals healths issues (road or traffic accident; Pregnancy and pregnancy-related complication like blood pressure, foetal heart rate, etc...) vitals parameters need to be continually measured. Imagine the case where the patient is living in a rural area or remote area with poor health infrastructure. That kind of situation needs the involvement of news technologies (telemedicine, IoT), technics to help to overcome the medical service delivery issues. Base on this background and due to the technologies issues and limitations in some area or region the authors had proposed a new technology to support the medical service delivery at a remote area. The proposed technology consisted of Narrowband Internet of Things (NB-IoT). It's a promising technology that provides long-range communications at a low data rate for sensors with reduced device processing complexity and long battery lifetime. This paper aims to investigate the realistic performance of NBIoT in terms of effective throughput and patient served per cell in the healthcare monitoring system in a rural area with both in-band and stand-alone deployment.
