In wireless communication as we just discussed, if there is a mountain on the route the wireless signal will be lost but if there was a cable going around the signal of the mountain will not be lost at all, it will just go on. The first cable I'll talk about is the twisted pair media type. It is primarily used for Ethernet and telephone networks, so this type of cable would primarily be used within a LAN. The advantages of this cable would be that it can also be used for telephone service, which means that when you call someone the pulses of electrical charges pulse through the cable through different types of terminal equipment to reach its destination. The disadvantage of using this type of cable would be that there is a transmission and distance limit, meaning that every mile or more you will need to use a repeater so that it can retransmit the signal and send it again through the same cable, this could cause the signal
