Today, June 20, is World Wi-Fi Day 2022. The event, initiated by the commercial group Wireless Broadband Allianceto emphasize the importance of wireless technology that enables the world to connect digitally.
Wi-Fi is a basic standard that has managed to guide the era of total connectivity in which we find ourselves. It is the main technology for creating local area networks through wireless connections Avoid having to pull cables in households, companies or anywhere, and also provide Internet access in the mobility of the billions of devices of all kinds that are connected today (more than 30,000 million in 2019) using this standard.
Although it’s been 23 years since telecommunications giants such as Nokia, 3Com, Airones, Intersil or Lucent have teamed up to form WECA (later transformed into the WiFi Alliance, which manages the standard), you have to go back many years to know their first steps. Nothing less than the golden Hollywood of the 1940s.
Here we must highlight the woman born Hedwig Eva María Kiesler in the former Austria-Hungary, who came from a Jewish family who moved in waters as diverse as those of the actress and engineer. Converted to Hedy LamarrThe stage name, proposed by her protector Louis B. Mayer (mogul and owner of Metro Goldwyn Mayer), was the first woman to play nude in the history of cinema and was also the discoverer of a wide range, the basis for protocols such as Wi-Fi or Bluetooth.
Although Lamarr was able to combine her career in Hollywood with studying telecommunications, she graduated in engineering. Another of his inventions was a system capable of detecting remote-controlled torpedoes used by the German fleet to control the Atlantic. The device was able to operate on 88 frequencies (equivalent to piano keys) and reproduce what we know today as spread spectrum frequency hopping.
This development provided the necessary technical basis for the next step to be taken in 1971. A computer network called ALOHAnet designed by the University of Hawaii sent various data packets over UHF waves used by television channels. Some of the protocols used in the experiment are the basis of the wireless connection we enjoy today.
It wasn’t until 1985 that the FCC released the ISM band so that anyone could wirelessly transmit data without licenses and royalties. Among other things, it covered the 2.4 and 5 GHz bands, which are the basis of current Wi-Fi. The 1990s were the key to launching a standard with projects such as wireless transmission between ATMs by NCR and AT&T using WaveLAN technology.
Finally, in the face of the need to create a common standard that would ensure network and device compatibility and promote the use of wireless technologies, the giants of this sector met at WECA, now known as the Wi-Fi Alliance of which more than 150 companies are part.
The moment of the definitive expansion of this technology was the creation of the IEEE 802.11 industry standard under the Wi-Fi trademark, compatible with all services of existing local area networks, but with wireless packet transmission. Since then, the IEEE 802.11 standard has improved in performance, security, range, new technologies, or the expansion of use to other radio bands.
To help users identify the device (and not the technical nonsense used previously) by the Wi-Fi Alliance simplified the generational names of the standard remaining as follows:
In addition to the nomenclatures, the Wi-Fi Alliance has adopted a new visual model that must appear on both the network device and the devices that connect to it, instead of the classic lettered versions. Much easier at first glance:
Wi-Fi 6 (6E) is a huge leap forward for the standard and is still in the mass adoption phase. However, the technology industry will not stop in front of anyone and the development of new standards begins a few years before they become available. Wi-Fi Alliance, Institute of Electrical and Electronic Engineers (IEEE) and major network equipment providers are already working on the next version.
As the final specifications have not been published, we know that the new standard will be marked with the technical name IEEE 802.11be. A new wireless standard is being developed to achieve and extremely high performance (EHT), so we can expect improved baud rates, lower latency, better management of connected devices, and expanded spectrum with higher bandwidth channels, which ultimately determine the data rate of the Wi-Fi signal and ultimately increase performance.
The main goal is to set up a wireless local area network with sufficient functions replace wired networks. In fact, this version is expected to be the first in practice to compete in the performance of wired Ethernet networks and to be able to handle high-bandwidth applications such as what comes from Metaverse, virtual / augmented reality, computing in cloud or streaming games.
The new standard will be introduced in 2024, and much is expected of it to see if we can finally get rid of the cabling. In any case, this technology is absolutely essential for wireless networking, and World Wi-Fi Day 2022, which is being celebrated today, is a recognition of its importance and of the scientists who brought us here.
