Wireless transmission refers to the transfer of data or information without the use of physical cables. This technology utilizes electromagnetic waves, such as radio waves, microwaves, or infrared signals, to send and receive data over distances. Common applications include Wi-Fi, Bluetooth, and cellular networks, which allow devices to communicate without being physically connected. The advantages of wireless transmission include increased mobility and convenience, as users can connect devices from various locations without the constraints of wires. However, it can also be susceptible to interference and security issues, making it essential to implement proper encryption and protocols to protect the transmitted data.
