What is Wi-Fi 7 and when will it come out?

The majority of us don’t pay attention to what is happening with Wi-Fi Router Technology, as we are not familiar with it due to 3G, 4G, and 5G network technology. IEEE announced last year that Wi-Fi 6E or Wi-Fi 6 Extended with 6GHZ band was now available to the public. Though industries are not quite prepared for higher data rates and lower latency, the Wi-Fi world has already seen a new boom.

There are no major changes coming to WiFi as the wireless era will operate in the 2.4, 5 and 6GHZ frequency band like Wi-Fi 6E. The features of this technology appear to significantly improve the connection’s reliability and stability. Find out what you need to know about Wi-Fi 7.

What is Wi-Fi 7?

Wi-Fi 7 is what we expect to be the next generation WiFi standard. We currently know about WiFi-7 with its technical name IEEE 802.11be, which is the same as the WiFi 6E routers. It is also knoreferred to IEEE 802.11be — extremely high throughput (EHT).

As a result of the release of WiFi 7, several new technologies that were not available in previous versions are available, such as 320 MHz bandwidth, 4096-quadrature amplitude modulation (QAM), multi-resource unit (RU), multiple-link operation (MLO), and multi-access point (AP) coordination. With the development of these cutting-edge technologies, Wi-Fi 7 achieves a higher data transmission rate and a lower latency than Wi-Fi 6. According to current estimates, Wi-Fi 7 will support a maximum throughput of 30 Gbps, about three times what Wi-Fi 6 offers.

Spectrums of 2.4GHz and 5GHz are unlicensed bands that are congested and limited. The quality of service (QoS) is often too low when running emerging applications (such as VR/AR). A 30 Gbps maximum throughput can be achieved through Wi-Fi 7 using the 6 GHz frequency band and new bandwidth modes like contiguous 240 MHz, contiguous 320 MHz, contiguous 160+160 MHz, and non-contiguous 160+160 MHz.

A 1024-QAM modulation, which allows each modulation symbol to carry ten bits, is the highest modulation order supported by Wi-Fi 6. The 4096-QAM modulation method improves the rate by up to 12 bits per modulation symbol in Wi-Fi 7. The same coding used in Wi-Fi 7 and Wi-Fi 6 results in 4096-QAM achieving a 20% rate improvement.

There is only minimal coordination between 802.11 access points in the current convention system. The WLAN capabilities of Merchant, such as programable radio controls and smart roaming, are noteworthy. In addition to the channel’s commitment to utilize radio assets and adjust distribution, the stack between APs will be shifted in order to achieve the lucrative use of radio assets. The upcoming Wi-Fi 7 standard incorporates a variety of access points as well as time and repetition locations, as well as intercell interface coordination and intercell MIMO integration. Thus, the interruptions between the APs are limited and air interface assets are heavily utilized.

Why we need Wi-Fi 7?

WLAN technologies have made home and enterprise networks increasingly reliant on wireless connections. The demands on throughput and latency for emerging applications have increased in recent years. These applications include high-resolution videos (involving up to 20 Gbps transmission speed), virtual reality (VR)/augmented reality (AR), online gaming (requiring less than 5 ms latency), remote office, online video conferencing, and cloud computing. Despite its dedication to improving user experience in high-density scenarios, Wi-Fi 6 – the most recent Wi-Fi standard – cannot meet these high requirements.

Release time?

As of May 2019, the IEEE 802.11be Task Group (TGbe) has been formally established to advance 802.11be (Wi-Fi 7). Both Phase 1 and Release 2 of the standard are planned for completion in 2019. 802.11be Draft 1.0 is scheduled for release in 2021, and Version 1 should be available by the end of 2022. The second release of the software is expected to begin at the beginning of 2022 and to be released at the end of 2024.

Ultimately, Wi-Fi 7 can only begin when we see current standards adopted more widely. Due to the slow pace at which Wi-Fi 6E is being deployed, we may still be several years away from seeing the next generation in our homes.
