Embedded WiFi Services for Wireless Patient Monitoring |
Patient Monitoring systems interpret and display patient’s vital signs based on parameters such as SpO2, ECG, blood pressure and temperature. In modern hospitals patient monitoring systems are connected to a central server where patient data is transmitted in real time over wireless networks such as Wi-Fi.
Embedded Wireless Labs worked with Dräger Medical, a leading manufacturer of medical equipment, to migrate their patient monitoring systems to a new

Wi-Fi network card. EWL developed a compact flash based driver to integrate the new Wi-Fi network card to the existing PCMCA.
Wi-Fi networks in hospitals typically deploy multiple access points which require the device’s scanning mechanism to detect AP channels quickly in order to maintain real time connection especially in roaming.
|
To optimize the system’s roaming capabilities, we designed the controller in the driver to scan only the country specified channels. This enabled the driver to scan only fewer selected AP channels and connect to the system faster with minimum packet loss. |
