Wi-Fi 6. IEEE 802.11ax. Uses and news.Maria Cruz Alcocer
IEEE 802.11ax, also known as WiFi 6, is a type of WLAN in the IEEE 802.11 suite. This new standard will be essential for the development of digitalization processes, as well as the implementation of technologies such as the 5G or Internet of Things.
It is designed to operate in the already existing 2.4 GHz and 5 GHz spectra.
SCENARIOS OF USE WI-FI 6
802.11ax is designed to:
- High density public environments: airports, trains, auditoriums, shopping centers, stadiums …
- in companies for deployments of 5G, Internet of Things (IoT),
- in homes where there is intensive use of the internet, and
- in offices that use applications with a high bandwidth consumption (eg VoIP).
- 802.11ax is also designed so that we can surf and download data more quickly from our mobile devices.
What does the use of WI-FI 6 provide us?
- Network decongestion: Every time we have more devices connected to the internet and the routers must be able to support several connections at the same time. The wifi 6 is designed to offer more reach and coverage, so that the action of connecting in “dense environments” will improve the user experience.
- More speed: This standard allows to reach speeds of up to 11 Gbps in three devices or more at a time, with a maximum speed of 5 Gbps in a single device.
- Performance: Wifi 6 will mean lower battery costs, up to two thirds less than what current standards on mobile devices consume, through a feature called Target Wake Time (TWT), which allows devices to remain inactive until they are It is his turn to transmit data with the use of a programming scheme negotiated with the APs.
All this is possible because, as we have said before, IEEE 802.11ax, in addition to using MIMO and MU-MIMO (multiuser, multiple input, multiple output), introduces OFDMA (Multiple access by orthogonal frequency division). It improves the global spectral efficiency, and thanks to its 1024-QAM modulation the WIFI 6 bandwidth responds much better in high density information scenarios and quadruples the WIFI 5 possibilities providing a higher performance. Although the nominal data rate is only 37% higher than IEEE 802.11ac, it is expected to achieve a 4x increase in user performance due to more efficient spectrum utilization with lower power consumption.
From the point of view of security, WIFI 6 supports the WPA3 protocol that will make your wireless connection much safer.
Wi-Fi 6, companies can take advantage of important innovations.
Wi-Fi 6 will dramatically improve the wireless experience and allow new uses of wireless networks that were not possible until now.
With WIFI 6 it decreases latency and provides a much better experience in applications such as streaming, video calls, shared desktop tasks.
The orchestration of the management systems of these separate networks is our next frontier.
With so many changes in the way we connect, we are facing an exceptional opportunity to combine technological change with strategic planning, as we explore how new wireless capabilities will change the way our businesses operate.
