Most homes today have multiple cable networks. The LAN network is one, but there is also cabling for television, telephone, speakers, et cetera. These various networks can be set up using standard cables that are prescribed for each separate network. However, this approach has distinct disadvantages. Once such cabling is installed, the function of each connection in the wall is determined. It leaves no room for flexibility. However, things can be done differently by using a multimedia network, a patch panel, and some active components.
