Answer: Wi-Fi was invented by Victor Hayes also knwon as “Father of Wi-FI”.
Wi-Fi is a remote systems administration innovation that permits electronic gadgets to interface with the web or speaks with one another without the requirement for actual links or wires. The expression “Wi-Fi” means “Remote Loyalty,” and it utilizes radio waves to send information between gadgets that are outfitted with Wi-Fi receiving wires.
- In a common Wi-Fi arrangement, there is a remote switch or passageway that is associated with a wired web association. The switch or passageway communicates a remote sign that gadgets with Wi-Fi capacities, for example, cell phones, PCs, tablets, or savvy home gadgets, can distinguish and interface with.
- When a gadget is associated with a Wi-Fi organization, it can get to the web or speak with different gadgets in a similar organization. Wi-Fi organizations can be gotten with passwords or other security conventions to forestall unapproved access.
- Wi-Fi innovation works on a particular arrangement of frequencies inside the electromagnetic range, regularly 2.4 GHz or 5 GHz. The reach and speed of a Wi-Fi association can shift contingent upon various elements, for example, the distance between the gadget and the passageway, the quantity of gadgets associated with the organization, and any actual snags, for example, walls or different boundaries, that might disrupt the sign. Generally speaking, Wi-Fi innovation has turned into a fundamental piece of current correspondence and is broadly utilized in homes, organizations, and public spaces all over the planet.
Basic Steps of How Wi-Fi Functions:
- A Wi-Fi switch is associated with a modem that gives admittance to the web. The switch changes over the information got from the modem into a remote sign.
- A Wi-Fi-empowered gadget, like a PC or cell phone, recognizes the remote sign and sends a solicitation to interface with the organization.
- The switch confirms the gadget and allots it an IP address, which permits it to speak with different gadgets on the organization and access the web.
- The gadget sends and gets information over the remote association, involving similar radio frequencies as the switch.
- The switch gets the information and sends it to the modem, which advances it to the web. Additionally, information sent from the web to the gadget is directed through the modem and afterward communicated remotely by the switch.
- The association between the gadget and the switch can be gotten utilizing an assortment of encryption conventions, for example, WPA2, which encodes the information communicated over the organization to shield it from unapproved access.
Who Invented Wi-Fi?
Wi-Fi innovation was not concocted by a solitary individual, but instead, it was the consequence of commitments from numerous people and associations after some time. Nonetheless, there are a couple of key figures who assumed significant parts in the improvement of Wi-Fi innovation.

He was important for a group of specialists at the District Logical and Modern Exploration Association (CSIRO) who were dealing with radio cosmology during the 1990s. While concentrating on radio waves, they found a method for communicating information utilizing radio waves at high paces, which established the groundwork for Wi-Fi innovation.
One more significant figure in the improvement of Wi-Fi innovation was Vic Hayes, a Dutch electrical specialist. Hayes led the IEEE 802.11 board of trustees, which made the principal guidelines for remote neighborhood (WLANs) in the last part of the 1990s. These norms shaped the reason for the Wi-Fi innovation we use today.
Other key supporters of the advancement of Wi-Fi innovation incorporate Dr. Hedy Lamarr, an Austrian-conceived entertainer and creator who co-designed recurrence bouncing, an innovation utilized in Wi-Fi and Bluetooth correspondence, and NCR Enterprise, an innovation organization that fostered the primary remote PC correspondence network in 1991. In this way, while there is nobody creator of Wi-Fi innovation, it is the aftereffect of commitments from numerous people and associations over the long haul.
