When was wifi invented:- The technology known as Wi-Fi, or Wireless Fidelity, allows computers to connect to the internet and communicate wirelessly through radio waves. Over several decades, many advancements and partnerships led to the creation of Wi-Fi. Although the exact moment or person involved in its conception is difficult to determine, the development of Wi-Fi may be dated back to the 20th century.
Wi-Fi has its roots in the efforts of well-known scientists and inventors who helped to establish wireless networking. Nikola Tesla, who in the early 20th century imagined a world with wireless communication, is a significant player in this trip. Future developments in wireless technology were made possible by Tesla's research of radio waves and wireless transmission.
Guglielmo Marconi is credited with creating the first wireless network for communication when he successfully sent radio signals over the Atlantic Ocean in 1901. Marconi's contributions constituted a critical turning point in the development of wireless technology and opened the way for subsequent advancements.
Moving forward to the middle of the 20th century, packet switching—a cornerstone of data communication—was first proposed, for future networking technologies, such as Wi-Fi, the concept of dividing data into bits for effective communication and rebuilding them at the destination proved to be an essential building block.
The brand consultancy company Interbrand came up with the phrase "Wi-Fi" in 1999. Nonetheless, the 1970s and 1980s saw the advancement of technology that eventually led to the creation of Wi-Fi. Hawaii deployed ALOHAnet, a groundbreaking computer networking system that used radio frequencies for wireless communication, in 1971. The foundation for the data transfer over wireless networks used by Wi-Fi was established by this early experiment.
The actual accomplishment was made in 1997 when the 802.11 working group was formed by the Institute of Electrical and Electronics Engineers, or IEEE, standards for wirelessly local area networking (WLAN). This was the first instance of Wi-Fi as we know it today. In 1997, the initial standard, 802.11, which offered a set of procedures for wireless communication, was approved.
After the first standard was established, several changes and upgrades were made to improve efficiency, safety, and range. In response to safety issues, Wi-Fi Protected Access (WPA) was introduced in 2003 and offered a stronger encryption method to secure wireless communication.
With the introduction of wireless connectivity to mobile phones, laptops, and other devices in the early 2000s, the use of Wi-Fi began to spread widely. Faster data rates were brought about by the 802.11g standard's launch in 2003, which increased users' attraction to Wi-Fi.
The IEEE released subsequent standards, including 802.11n, 802.11ac, and 802.11ax, as technology developed. These standards each offered better features, higher data rates, and enhanced performance. Due to the broad use of Wi-Fi in residences, workplaces, and public areas made possible by these standards, wireless connectivity is now a necessary aspect of daily life.
Conclusion: Collaboration spanning several decades led to the creation and development of Wi-Fi. Wi-Fi has advanced significantly in delivering seamless wireless connectivity, starting with the early tests of Tesla and Marconi and continuing through the IEEE's standard-setting work. Wi-Fi has become an essential technology of today, linking billions of devices globally and influencing how we communicate, work, and live.
