What Are Wireless Transmission Media?
Wireless transmission media refers to a form of unguided media that does not require the establishment of physical links between two or more devices. Wireless transmission is used when installing cables or using wired transmission would be impossible, impractical or inconvenient.
Wireless transmission can either be omnidirectional, where waves are propagated in all directions, or directional, where point to point focused beams are used. The distance covered by wireless transmission media ranges from a few meters to thousands of kilometers.
Examples of wireless transmission media include infrared, microwaves, Bluetooth, communication satellite and radio transmission. Despite their numerous advantages over wired communication media, wireless media is more prone to security threats, hacking and have a high initial setup cost.
