How GPS Works Through Satellite | Global Positioning System Satellite Communication Satellite Communication is a form of wireless communication in which satellites are the main objects. These satellites are commonly called communication satellites. Communication satellites are ideally placed to provide the telecommunication links between different places across the globe, These satellites enable us to communicate over large distances Satellite communication can be used for many applications such as international telephone calls, providing communications to remote areas of the Earth, providing satellite communications to ships, aircraft and other mobile vehicles. Figure 1.14 shows satelites orbiting around the Earth. How GPS Works Through Satellite | Global Positioning System Global Positioning System The Global Positioning System (GPS) is global navigation satellite system. This position-finding system uses satellites to determine precise locations on the surface of the...
Twisted Pair Cable | STP | UTP | Twisted Pair Cable Twisted Pair cables are the most popular transmission media for transferring data on a computer network. They are especially used in Local Area Networks. Twisted pair wires consist of two strands of copper twisted together. The twists allow the data signals to travel more as compared to a regular copper wire. The more twists per centimeter, the further the signal can travel.Twisted pair cable is of two types: Unshielded Twisted Pair (UTP) If the wires are unshielded, they are called Unshielded Twisted Pair cables, as shown in Figure 1.10(a). Shielded Twisted Pair (STP) If the wires are shielded, they are called Shielded Twisted Pair cables, as shown in Figure 1.10(b). Characteristics of Twisted Pair Cables It is the least expensive type of cable. It is easy to install. Coaxial C...
