25 years ago, the Institute of Electrical and Electronics Engineers introduced the 802.11 Wi-Fi standard. Since then, Wi-Fi speeds have increased and changed the world of Wireless internet. In the following, we discuss the process for this technology.

The world without wires

In the world before Wi-Fi, access to the Internet and local networks with wired connections was taking place At that time, either telephone lines or Ethernet cables were used for this purpose. But in June 1997, the Institute of Electrical and Electronics Engineers (IEEE) introduced the first Wi-Fi standard and the process of changes began. Thanks to technologies such as CDPD and Mobitex, the commercial application of this idea became possible. But using these technologies was also very expensive and they were mainly used for public safety services.

In 1990, two large companies, NCR and AT&T, started the development of the first commercial Wireless LAN product called WaveLAN. After several years of waiting, it was time to introduce the first version of Wi-Fi, which was initially called IEEE 802.11b Direct Sequence, but finally the name Wi-Fi was chosen for it, which stands for Wireless Fidelity. Two years later, the companies decided to establish the Wi-Fi Union to make better decisions about the management and naming of this standard.

Over the past 25 years, at least 8 major Wi-Fi standards have been introduced. The number 802.11 is still used for the original name of these standards, but the Wi-Fi Union uses simpler names for simplicity. Next, we take a brief and useful look at the standards.

  • 802.11 (1997): The first Wi-Fi standard with a maximum speed of 2 Mbps and band 2. 4 GHz was supported.
  • 802.11b (1999): In this version, the maximum speed reached 11 Mbps and it was the first Wi-Fi version that was widely used. .
  • 802.11a (1999): In this version, the communication speed in the 5 GHz band reached 54 Mbps. But since most users used 802.11b, this version was not used much.
  • 802.11g (2003): With this update, users can enjoy maximum 54 megabits per second and became very popular among businesses and home users.
  • 802.11n (2008): This new version became known as WiFi 4 and It allowed a maximum speed of 600 Mbps.
  • 802.11ac (2014): Wi-Fi 5 supports speeds between 433 and 1100 Mbps in the 5 GHz band.
  • 802.11ax (2019, 2020): Wi-Fi 6 and 6E support speeds between 600 and 9608 Mbps in the 2.4, 5, and even 6 GHz bands.
  • 802.11be: products based on Wi-Fi 7 standard are going to go to the market next year. Thanks to this new standard, users in ideal conditions can use the maximum speed of 40 Gbps.
  • What is Wi-Fi 7 and how is it different from previous generations?

Although the first Wi-Fi version was introduced in 1997, but in 1999 this standard was widely available to users. In 1999, Apple played an important role in the spread of Wi-Fi by introducing this feature for the iBook laptop.

In 2003, with the introduction of the 802.11g standard, which supported a maximum speed of 54 Mbps, this technology became popular. was placed more and the manufacturers of home modems also widely paid attention to this technology. Currently, 802.11n and 802.11ac standards are the most widespread among users.

These days, almost all users use Wi-Fi technology, and thanks to this technology, providing Internet in public places such as coffee shops, Hotels and airports have become possible. It is difficult to imagine what our world would be like without Wi-Fi. This technology is here to stay and it looks like it will be with us for decades.
