No, wireless technology is not only possible due to inductance, which occurs when an electric and magnetic field interact. In fact, wireless technologies such as Wi-Fi, Bluetooth, cellular, and satellite communication rely on the transfer of information using a combination of electromagnetic and infrared (IR) radiation for communication between two or more devices.
EM radiation is created by the movement of electric charges and can occur across a range of frequencies and wavelengths, ranging from radio to infrared radiation. This radiation can be used to transmit information between two points over short or long distances, with devices having antennas that convert currents into radio waves, and receivers equipped to detect radio waves and convert them back into electrical signals.
In contrast, IR radiation involves transmission of signals through waves of infrared light. IR radiation is used for a variety of applications, such as remote control systems and motion detectors.
In summary, a variety of wireless technologies are possible due to different kinds of radiation, including electromagnetic and infrared radiation, and do not necessarily require the presence of inductance.
