Why do Wi-Fi waves have such short distance and some microwaves are used for sending information through long distances?
the difference in transmitted power levels and antennas ... simple as thatPhoto1234 said:Why do Wi-Fi waves have such short distance and some microwaves are used for sending information through long distances?
Wi-Fi is a wireless networking technology that allows devices to communicate with each other and the internet without the need for physical cables. It works by using radio waves to transmit data between devices, typically in the 2.4GHz or 5GHz frequency bands.
Wi-Fi range is limited to short distances because it operates on short-range radio waves that are easily disrupted by physical barriers such as walls and furniture. Additionally, the strength of the signal decreases the further it travels, resulting in a limited range.
Microwaves are a type of electromagnetic radiation with wavelengths between 1 millimeter and 1 meter. They are used for long-distance communication because they have a longer range and are less likely to be disrupted by physical barriers compared to shorter wavelength radio waves used for Wi-Fi.
Microwaves and Wi-Fi waves both fall under the category of radio waves, but they have different wavelengths and frequencies. Microwaves have longer wavelengths and lower frequencies, allowing them to travel longer distances and penetrate physical barriers more easily than Wi-Fi waves.
There is currently no evidence to suggest that Wi-Fi and microwaves used for communication pose any health risks. Both types of waves are considered non-ionizing radiation, meaning they do not have enough energy to cause damage to cells in the body. However, it is always recommended to limit exposure to any type of radiation as a precautionary measure.
