<P> "Structured wiring" is the general term for 21st century On - premises wiring for high - capacity telephone, video, data - transmission, security, control, and entertainment systems . Installations usually include a central distribution panel where all connections are made, as well as outlets with dedicated connections for phone, data, TV and audio jacks . </P> <P> Structured wiring enables computers to communicate with each other error - free and at high speeds while resisting interference among various electrical sources, such as household appliances and external communications signals . Networked computers are able to share high - speed Internet connections simultaneously . Structured wiring can also connect computers with printers, scanners, telephones, fax machines, and even home security systems and home entertainment equipment . </P> <P> Quad - shielded RG - 6 coaxial cable can carry a large number of TV channels at the same time . A star wiring pattern, where the wiring to each jack extends to a central distribution device, facilitates flexibility of services, problem identification, and better signal quality . This pattern has advantages to daisy chain loops . Installation tools, tips, and techniques for networked wiring systems using twisted pairs, coaxial cables, and connectors for each are available . </P> <P> Structured wiring competes with wireless systems in homes . While wireless systems certainly have convenience advantages, they also have drawbacks over copper - wired systems: the higher bandwidth of systems using Category 5e wiring typically support more than ten times the speeds of wireless systems for faster data applications and more channels for video applications . Alternatively, wireless systems are a security risk as they can transmit sensitive information to unintended users over similar receiver devices . Wireless systems are more susceptible to interference from other devices and systems, which can compromise performance . Certain geographic areas and some buildings may be unsuitable for wireless installations, just as some buildings may present difficulties installing wires . </P>
