3. Do some Internet research on the use of VLANs in hospitals. Summarize the benefits of using VLANs in hospitals and identify examples of how St. Luke’s could further enhance its wireless network by implementing VLANs.

VLAN refers to Virtual Local Area Network. It is a subnetwork that can group together collection of devices on separate physical Local Area Networks. VLANs allow network administrators to group hosts together even if the hosts are not directly connected to the same network switch.

Considering the large number of departments in hospitals, with each departments having functions different from the others, Virtual LANs allows various users(the departments) to be grouped together according to their networking needs, regardless of their actual physical locations. Subdividing the LAN into smaller segments, or VLANs, increases overall reliability, security, and performance, and makes the network easier to maintain.

Because of the largeness of St. Luke's hospitals and their mission of delivering highly reliable and feature-rich advanced network solutions, virtual LAN will help to provide a resilient and scalable network solution within the hospital's budget.

St. Luke should implement virtual LAN that can produce a higher bandwidth with lower-cost, a longer-term model based on servers, networking products and homogenous network components to deliver centralized management of computing across the hospital network.
