Summary:
The use of wireless communication systems has seen explosive growth in the field of clinical medicine. Modern medicine would not be possible without the rapid and accurate sharing of patient data among the hospital staff. For many reasons, including legal issues, a physician's instructions on patient care and prescription must be accurately transmitted and stored, making a primary communication system with an emergency backup essential. The Personal Handy-phone System (PHS) has long been used in Japanese hospitals, especially as a component of the nurse call system, but this will change when public PHS service ends at the end of January 2021. Wireless LAN with Voice over IP (VoIP) technology has been proposed as a possible alternative, but it has major drawbacks because the explosive growth in data traffic through IP networks is having an impact on the quality of voice calls, and traffic will undoubtedly grow in the future. An exciting alternative is the shared EXtended Global Platform (sXGP), a TD-LTE compatible cordless telephone system that uses the 1.9 GHz band, which has not been used for mobile communication systems on IP networks or widely studied. To test its potential and possible problems, we investigated the effectiveness of sXGP by measuring its diffraction effect in comparison with other frequency bands. Our results show that communication can effectively be done using 1.9 GHz radio waves. Although it would seem to be disadvantageous in terms of cost to install separate voice and data communication networks, making voice communication systems independent of data communication systems has advantages that can maintain a safe, efficient communication environment and increase patient safety.
