The Repeater Allows The Network To Travel Farther

  The repeater allows the network to travel farther

  The repeater allows the network signal to be driven so that they are transmitted farther. Due to the influence of transmission line noise, the digital signal or analog signal carrying information can only transmit a limited distance. The function of the repeater is to regenerate and transmit the received signal, thus increasing the distance of signal transmission.

  It connects two or more segments of the same network. For example, Ethernet often uses the repeater to extend the cable length of the bus. The length of the standard cable Ethernet is 185 meters long and can have up to 5 segments. Therefore, the maximum network cable length can be increased to 925 meters The In general, the network part of the repeater is the network segment, not the subnet.

  The repeater can connect two LAN cables, re-timed and regenerate the digital signals on the cable, and then send them out, which is the first layer of the OSI model - a typical function of the physical layer. The role of the repeater is to increase the coverage area of the LAN.

  For example, the Ethernet standard specifies that the maximum length of a single-segment signal transmission cable is 500 meters. However, when connecting the 4-segment cable with a repeater, the signal transmission cable in Ethernet can be up to 2000 meters. Some brands of repeaters can be connected to different physical media cable segments, such as fine coaxial cable and cable.

  The repeater only sends data from any cable segment to another cable regardless of whether there is any data in the data or data that is not suitable for the segment.

  Involving the transmission and reception of the very high frequency radio spectrum lines. This limitation is overcome by the "repeater", which picks up the weak signal and amplifies them later at different frequencies. Thus, using a repeater, a low-power user (such as a mobile station) with a user who can communicate directly to the user's contact will be the other.
