To support healthcare organizations responses, many companies have started solutions to be satisfied the specific requirements of healthcare programs, and plans. This paper presents a designed and implemented care system for health diagnosis based on GPS location in the hospital. The designed handheld care system is implemented using an embedded Visual C++4.0 and Pocket PC2003 software development kit (SDK) in an 802.11 wireless network. We are confident that the research provides sufficient proof of the usefulness of this ubiquitous health system for the collection of care management information. The proposed system consists of a care management module for health diagnosis, a personal record module, a data transport module, and an image information management module for the clinic. System uses an applied security mechanism for critical data, and is accessed and controlled according to the GPS locations in the hospital. Also, for emergency status, transmission functions of clinic information are implemented using a wireless LAN protocol environment.
