Respond to discussion 150 words minimum Transmission mediums used in networking are responsible for carrying data over a given length of space. The medium can be wired or wireless. Many people use wireless technologies in their businesses and homes. Large businesses and corporations use a combination of wired and wireless technology. Some wired technologies are more expensive than others. Consequently, wired technologies like fiber optics offer extremely high speed data transmission. Cheaper technologies use coax cables and twisted pair wires. Higher grades of twisted pair wires can provide transmission speeds of up to 10 Gbps at 600 MHz (2012). Free space transmission mediums include infrared transmission, short-range wireless, satellite, and microwave transmission. Orthogonal Frequency Division Multiplexing is a modulation technique used in wireless standards, including the 802.11n standard. OFDM has been adopted by many broadcasting standards. OFDM provides high data rates using equally spaced signals that carry their own payload. There are different variations of OFDM, including Vector OFDM. VOFDM uses Multiple Input Multiple Output modulation. MIMO uses multiple antennas to transmit multiple signals to enhance connectivity (Poole, 2016).

Transmission mediums are fundamental components in networking that enable data transfer between devices. These mediums can be broadly classified into wired and wireless categories, each with distinct advantages and limitations. Wired mediums, such as fiber optic cables, coaxial cables, and twisted pair wires, are traditionally favored for their stability, security, and high data transfer speeds. Fiber optic cables, for example, utilize pulses of light to transmit data, providing extremely high bandwidth and minimal signal degradation over long distances (Bandyopadhyay & Putnam, 2020). In contrast, coaxial cables and twisted pair wires are more cost-effective and easier to install, often used in local area networks (LANs).
Wireless transmission mediums include infrared, microwave, satellite, and short-range wireless technologies such as Wi-Fi. Wireless systems offer flexibility and mobility but may face challenges related to interference and security. The evolution of wireless standards, notably the adoption of Orthogonal Frequency Division Multiplexing (OFDM), has significantly improved wireless data rates. OFDM works by splitting data into multiple sub-signals that can be transmitted simultaneously over different frequencies, making it highly resistant to frequency-selective fading (Tse & Viswanath, 2005). Variations of OFDM, such as Vector OFDM (VOFDM), incorporate advanced modulation techniques like Multiple Input Multiple Output (MIMO), where multiple antennas are used to transmit and receive data streams, further enhancing network capacity and reliability (Poole, 2016).
The development of transmission mediums reflects ongoing technological advancements aimed at increasing speed, reliability, and coverage. Fiber optics, in particular, have become crucial in backbone infrastructure due to their capacity to support high-speed internet and data centers. As technology progresses, wireless mediums continue to evolve, incorporating sophisticated modulation and multiplexing techniques like OFDM and MIMO. These innovations are vital in supporting the rising demand for high-definition video streaming, cloud computing, and the Internet of Things (IoT). Looking forward, wireless technologies are poised to become even more pervasive with the increasing use of drones and satellite constellations to provide global coverage, reducing reliance on traditional wired infrastructures (Andrews et al., 2014).
In conclusion, the choice of transmission medium depends on factors such as speed requirements, distance, cost, and environment. High-speed fiber optics serve essential backbone functions, while wireless mediums provide flexibility and mobility—both are integral to modern networking. As these technologies continue to advance, they will support the expanding ecosystem of interconnected devices and services that define contemporary digital life.
