2.4. Radio Frequency Interference
Twisted pair cable and other in-house wiring are used to carry signals from one end, within an office or a home, to another end. Part of the signal energy is lost during transmission; becoming heat and electromagnetic radio waves. At high frequencies, the signal loss is relatively heavy, and the amount of radiation could become quite significant to the degree that it could affect other sensitive radio transmission systems occupying the same frequency band. The radio interference caused by twisted pair cable or in-house wiring can be considered as an extension of the crosstalk effect. Crosstalk is an electromagnetic phenomenon between two pairs of cables laid next to each other. The same electromagnetic wave that ...
