In-hospital PHS to smartphone NST Globalist’s sXGP

パルモスマートコールのナースコールボタン(Palmo Smart Call nurse call button)

NST Globalis is deploying sXGP as a telephone solution within hospitals. sXGP stands for private LTE, which does not require a license, and refers to a private communication method that uses the same communication method as smartphones and mobile routers.
Hospitals and nursing care facilities still use PHS as their own communication method. It is said that 90% of hospitals and nursing care facilities use PHS. The reason for this is that PHS does not easily affect medical devices.

However, PHS does not allow data communication. As a result, many staff at hospitals and nursing care facilities carry two devices: a PHS and a smartphone.
sXGP uses the same radio band as PHS (1.9 GHz band), making it possible to use smartphones in hospitals and nursing care facilities without worrying about radio wave interference. Staff will be able to use their smartphones not only to make calls and nurse calls, but also to use business apps, making it easier to work more efficiently. For example, if you use Wi-Fi to watch training videos in your free time, that alone will help reduce your workload.
The company will also promote its wireless nurse call “Palmo Smart Call.”

Reception of nurse calls, cooperation with various sensors, and calling functions can be integrated into a single smartphone.
The nurse call signal uses LoRa (920MHz band) and is sent via Wi-Fi to a smartphone dedicated to nurse calls. Nurse calls are instantly shared on each staff member’s smartphone, and who is responding is also displayed, avoiding duplication of calls.

Additionally, if multiple nurse calls occur, they will be displayed on the smartphone screen in the order in which they were called, and the calls will disappear once the task is completed, making it possible to prevent forgetting to respond when multiple calls occur.
Establishing a PHS-based nurse call system involves updating wired lines, but Palmo Smart Call requires only the installation of wireless equipment, so it is relatively easy to update.
