There are a few reports of its use at home or during emergency transport. Objective: The aim of this study was to test whether CTG and other perinatal information can be transmitted accurately using an experimental station with a 5G transmission system. Methods: In the research institute, real-time fetal heart rate waveform data from the CTG device, high-definition video ultrasound images of the fetus, and high-definition video taken with a video camera on a single line were transmitted by 5G radio waves from the transmitting station to the receiving station. Results: All data were proven to be transmitted with a minimum delay of less than 1 second. The CTG waveform image quality was not inferior, and there was no interruption in transmission. Images of the transmitted ultrasound examination and video movie were fine and smooth. Conclusions: CTG and other information about the fetuses and pregnant women were successfully transmitted by a 5G system. This finding will lead to prompt and accurate medical treatment and improve the prognosis of newborns. %M 32897237 %R 10.2196/19744 %U http://medinform.jmir.org/2020/9/e19744/ %U https://doi.org/10.2196/19744 %U http://www.ncbi.nlm.nih.gov/pubmed/32897237
