Coaxial Cable is also widely used in the telecommunications industry, such as the telephone system where coax reaches the pole or drop nearest to the subscriber’s house, and a twisted-pair cable comes into the house and to the telephone.
Coaxial can also be a good solution for providing residences and small business with high-speed data access because it is generally wired in a bus topology, it requires less cable than other solutions and does not require a hub, cutting down on cost.
The construction of coaxial cable is designed to keep a distance between the inner conductor and the outer shield, which is one factor in determining the impedance rating of the cable.

 Coaxial cable for wireless communications
The essential idea behind coaxial cable (for the first two cases) is simple and elegant: two concentric conductors to provide a self-shielded line, minimizing radiation loss that might affect other components, with as little attenuation as possible.
As mentioned previously, bonding of these four basic cable elements to each other is receiving increased attention from manufacturers, particularly the bonding of the center conductor to the dielectric and the bonding of tape-and-braid outer conductors to the dielectric.
Radiating cables A radiating cable couples the RF energy propagating along its length to the surrounding environment, with a minimum of downline attenuation, and thereby functions as a continuous antenna.
