Wired and Wireless Transmission Media

Unlike communications using wired transmission media such as twisted-pair, coaxial, fiber-optic cables, wireless media don’t use solid substances to transmit data. Rather, wireless media send data through air or space using infrared, radio, or microwave signals. Why would you want to use wireless media instead of cables? One instance would be in situations where cables can’t be installed or the costs to do are prohibitive. More and more colleges are implementing wireless computing capabilities on their campuses because users demand connectivity but the cost of wiring classrooms is too great.
