Information transmission medium from location P to location Q in space is called wireless transmission. This refers to the process of transmitting information between two or more points that are not connected by any physical medium, such as cables or wires. Instead, information is transmitted through the air using electromagnetic waves. Examples of wireless transmission include Wi-Fi, Bluetooth, and cellular networks. In contrast, wired transmission involves using physical cables or wires to transmit information between locations. Cabled transmission and asynchronous transmission are specific types of wired transmission.
