Merits of duplicate LAN cabling in hospitals.
Our hospital wired three LAN cables separately to improve the data distribution range. One LAN is between the various sections of the hospital (hospital LAN), another is within each section (section LAN), and the other is connected to the Internet (open LAN). The section LAN was connected to the hospital LAN to enable data exchange. Data from the section LAN for common use is collected through the hospital LAN and stored in the central server The duplicate cabling and separate LANs increased the independence of each LAN and the system within each section. The section systems can be changed at anytime without the necessity of reconstructing the whole hospital information system. The data transfer speed of each cable increased. Hospital information processing systems often use a distributed-processing centralized management system. Because of advances in technology, each section can now take responsibility for developing their own system, making the responsibility of the information processing section responsible for hospital information systems more limited than previously. Herein, we show the merits of separate cable installation.
