Wireless transmission can be achieved through________________________?
Show answer Hide answer
Answer: D. all of the above
Explanation
Wireless transmission can be achieved through radio waves, microwaves, and infrared. All three technologies transmit data through the air without physical cables. Different frequencies and wavelengths suit various communication distance requirements. Wireless networking relies on electromagnetic radiation to carry digital data. Radio waves offer wide coverage for broadcasting and mobile communication systems. Infrared signals require line-of-sight positioning for short-range remote controls.
Wi-Fi routers use radio waves to connect laptops and smartphones to local networks. Satellite dishes communicate using high-frequency microwave transmission links. TV remote controls transmit commands reliably across rooms using infrared light. Radio waves represent only one valid wireless transmission medium among several. Microwaves describe just a specific frequency band used for directional links. Infrared is limited to short-range line-of-sight communication applications.
