Develop, in general terms, a cost$-$effective structured cabling plan for a tiered LAN within a scientific R&D organization that is building a new five$-$story research facility. The first floor will contain the lobby and administrative offices. The second and third floors will contain labs that utilize fairly large pieces of heavy$-$power$-$consumption equipment $($e$.$g$.,$ small linear accelerators and reactive ion chambers$).$ Numerous technicians and scientists will be working on this floor and data requirements include high$-$speed transmission of high bandwidth data $($e$.$g$.,$ color video$).$ The fourth floor will contain offices for the lab personnel and the fifth floor will contain executive offices. Your plan should describe and illustrate the horizontal cabling for each floor as well as the vertical cabling runs.
