Evaluation of QoS in data mobile network for vital signs transmission

The quality of pre-hospital care and timely coordination of the stakeholders in the public health network, play a very important role maintaining the status of a patient. The integration of technology in emergency scenarios is proposed as a tool to improve response times, monitor patient status and even perform video-consultations between the site of the incident and medical personnel located in certain clinics. The parameters of QoS (maximum latency and percentage of packet loss) that the network must provide to the different telemedicine services, as well as the logical infrastructure, physical infrastructure and network devices that comprise it were also defined. The performance of the LTE network for the uplink data flow was evaluated through NS-3 software. The results show that the network performance decreases when the traffic generated by other users increase or by increasing the bit rate of the information from ambulances. Additionally, it showed that the network performance can improve substantially by increasing radio resources or bandwidth channel of the LTE network.
