Wi-fi: –Wi-Fi (wireless fidelity) is a high-frequency radio wave technology that is used to send or receive data in between wi-fi enabled devices (like computers, smartphones, printers, tablets, etc.) wirelessly. It uses high frequency from 2.4Ghz to 5Ghz to transmit data. The higher the frequency more the data can transmit.

Wi- fi can transmit data within a range of up to 250 meters in outdoor areas without any obstruction. Any physical obstruction like a wall, or tree can reduce the covering range due to absorption, or reflection of the wave.
