Wireless network technology is a technology that provides point-to-point or network structure.

The next online scientific seminar of the 3rd department of the Institute of Information Technology of ANAS was dedicated to the perspectives and applications of Wi-fi 7 technology.

The programmer of the institute Tabriz Agashov spoke about the classification of wireless network technologies, noting that it has individual, sensor, small local, large local, global and satellite networks.

Agashov noted that Wireless Local Area Networks (WLANs) were initially created in environments such as airports, Internet cafes and hotels, but at that time wireless networks were underdeveloped compared to other wired networks in terms of data transfer speed, coverage and equipment cost. He said that over time, the new IEEE 802.11 wireless networking standards and wireless networks have improved, especially in terms of coverage and data transfer speeds.

In addition, there has been an increase in the use of wireless equipment and mobile devices due to lower supply costs. Even today, wired networks created in the home and office environment are being replaced by WLANs.

Speaking about the stages of development of Wi-Fi technologies, the speaker noted that the economic value of the Wi-Fi market in 2018 will be two trillion dollars: a new study commissioned by the Wi-Fi Alliance, its value will increase to $ 4.9 trillion by 2025.”

The researcher also gave a brief overview of Wi-Fi 5 and Wi-Fi 6 technologies. He said that Wi-Fi 6 transmits data to users 40% faster than Wi-Fi 5 or 802.11ac.

He then talked about the prospects and applications of Wi-Fi 7 technology, noting that Qualcomm is currently developing the seventh generation of standard wireless communication. This new standard is called IEEE 802.11be. Wi-Fi 7 is designed to use 2.4 GHz (2.400 to 2.495 GHz), 5 GHz (5.170-5.835 GHz) and 6 GHz (5.925-7.125 GHz) frequency bands and to support transmission speeds of up to 30 Gb / s.

He noted that since 2001, Wi-Fi has been used mainly in products such as routers and computers, but since 2006 there has been a sharp increase in the use of Wi-Fi in phones, TVs, games and tablets, and cameras. Over the past five years, several product categories have been added to the list. For example, we can show in buildings, smart homes and other categories, including heating, lighting, vehicles, and other devices.

Speaking about the applications of Wi-Fi 7 technology, the researcher said that the list includes video broadcasting, video or voice conferencing, online games, industry and the Internet of Things, as well as interactive telemedicine.

He also noted that it will be based on Wi-Fi 7 Extreme High Throughput (EHT) protocol, which will significantly improve the performance of wireless networks compared to current standards.

At the end, the researcher answered the questions of the seminar participants.

Rashid Alakbarov, executive director of the Institute, head of department, PhD in technical sciences, associate professor, noted the need to study international experience and prepare articles on the prospects and areas of application of Wi-Fi 7 technology.
