the walls of the building. 2 cat5 cables of 40 meter length, 2 cat 5 cables of 25 meter length, 1
cable of 35 meter length and a small patch cord for connecting the server with the hub. Some
extra cables are estimated for inclusion of the rise and fall in the network and increase the
efficiency of the cabling plan.

10
NETWORK DESIGN/WIRELESS NETWORKS
c. Indication of the unused cables at the locations
There are no extra unused cables in the network and it is essential for the creation of
an effective cabling plan (Oliviero and Woodward 2014). The location of the device is
maintained according to the network cabling plan and the existing cables are used for
reducing the network cabling cost.
d. Indication of the power location and power protection plan.
