Transmission cabling and techniques - Assignment ExampleThe advent of televisions and transmission of not only calls but also video or visual signals called for the introduction of wideband transmission medium in the form of broadband copper coaxial cables in the 1930s. This was followed by the development of coaxial cables into tandem that contained microwave radio put across systems in the 1970s. These were broadband systems in which television and conversation signals travelled through radio with the help of a number of towers. Microwave relay had the advantage of lour construction and maintenance costs as compared to coaxial cables (Migliavacca 143).Fiber optic cables that used light to transmit signals came before more advanced techniques of LAN (local surface area networks) as forms of transmission media. It was after the introduction of fiber optic cables in the 1980s that more advanced techniques like OFDM, which is the acronym of orthogonal frequency-division multiplexing and MIMO which is multiple-input and multiple-output, were introduced as a modes of encryption digital data (Pejanovic-Djurisic, Enis, and Ramjee 94). The OFDM technology is a mode of encoding digital data on a number of carrier frequencies while MIMO is the application of some(prenominal) antennas on both ends of the transmission and receiving to enhance communication performance. Wireless technology is pass judgment to advance further with predictions such as the use of light bulbs that yield the capacity to transmit data through illumination. Additionally, wireless technology is expected to advance further to the implantation of devices with the capacity to receive wireless transmissions on humans. This is expected to notify people of particular events
