Channel bandwidth communications wiring in judging the performance of one of the most important parameter indicator of the size of the bandwidth also by environmental factors, of which the most influential factor is temperature.
Medium copper cabling system, the bandwidth used for each 100 meters UTP channel bandwidth (usually MHz) to represent. Channel bandwidth refers to the case of the same signal to noise ratio to determine the channel frequency range. Next-generation standards such as Category 6 or 7 class standards and the existing standards of the lower categories of difference lies in the available (effective) bandwidth difference. Bandwidth and information transmission capacity is the relationship between a long time ago by the ClaudeShannon discovered this law is known as Shannon's Law. In general, the higher bandwidth cabling system means higher data transfer rates.
In a measured MHz channel bandwidth and to Mb / s to measure the information transmission capacity or data transfer rate of a fundamental relationship exists between. Can use the freeway mainline traffic flow to the image shows the concept of bandwidth and data transfer rate between the relations. Bandwidth can be compared to the number of highway lane, the data transfer rate can be compared to the passage of traffic or the number of vehicles per hour. One way to expand the traffic flow is widened highway, while the other approach is to improve the road quality and the elimination of bottlenecks. Similarly, let the frequency within the available bandwidth for each Hz frequency carry more bits of information capacity is also possible, but this requires better signal to noise ratio.

Today, most of the LAN system to control the noise source is generated in the transmission line right and receive near-end crosstalk between wire pairs. When all of the near-end crosstalk sources are taken into account, then the signal to noise ratio measured in decibels and the cumulative power attenuation crosstalk ratio (PSACR) of the same value. Category 6 standard has the advantage of the bandwidth in the 200MHz frequency range will be cumulative power attenuation crosstalk ratio (PSACR) control in the context of greater than zero, so that its available bandwidth can be reached Category 5 cabling system twice as high.
