Wi-Fi standards and protocols have come a long way in recent years. Leaps in user experience, the capacity to handle far higher device density, and the growth of use-cases where Wi-Fi previously couldn’t compete. The first step was to update from Wi-Fi 5 to Wi-Fi 6. (802.11ax). The ability of Wi-Fi 6 to use OFDMA, the same technology on which 5G is built, makes substantial progress toward more deterministic scheduling by coordinating airtime among clients and minimising the collision domain.
Wi-Fi 6E will be used throughout the facility, allowing for increased productivity. We are now in the midst of yet another Wi-Fi evolution with Wi-Fi 6E. Wi-Fi 6E use the same protocols and standards as Wi-Fi 6, but adds 1200 MHz to the 6 GHz bandwidth to expand beyond the 2.4 and 5 GHz bands. As more regulators and countries see the social and economic ramifications of easy and low-cost wireless access, the 6 GHz spectrum is being opened up around the world. This bodes well for Wi-Fi 6E, as significant investments in new products accelerate global digitization, resulting in increased productivity, better learning opportunities, more inclusive experiences, and faster business.
A NEW CLEAN SPECTRUM
It is estimated that by 2023, more M2M/IoT devices will be connected to Wi-Fi than people. So far, the CAGR for wireless IoT device growth has surpassed 20%, and we are only getting started. This compared to a 10% increase for more typical user devices like smartphones, laptops, and tablets.
Fundamentally, this means that next-generation networks will face new hurdles in handling high density efficiently. The availability of a clear spectrum is important to Wi-efficiency. Fi’s You are less likely to have to compete with other users or networks when moving traffic because you have a clear spectrum.
Because of Wi-Fi 6E, wireless networks will be able to carry more traffic at faster rates and with lower latency. The 6 GHz spectrum is much cleaner, with enough of elbow room and channels to support the ever-increasing number of devices and things.
Wi-Fi 6E has the significant advantage of requiring a Wi-Fi 6 (or newer) stack, implying that Wi-Fi 5 or previous releases cannot be used at the new 6GHz frequency. This means that all 6GHz Wi-Fi devices may be scheduled efficiently. However, don’t exclude out the 2.4 and 5 GHz bands. Because each brand has its own set of advantages and weaknesses, we will continue to require and utilise the full unlicensed Wi-Fi spectrum.
WI-FI 6E ADDRESSES HIGHER DENSITIES RELIABLY
The majority of today’s consumers own numerous devices, including a laptop, tablet, phone, smart watch, and health device. Simultaneously, our environments are becoming smarter and more rich with technologies designed to boost our productivity. Add to that the fact that our workplaces are growing more dense, and new hybrid work models and open-office arrangements are gaining popularity. These areas allow for a more flexible workplace designed for improved collaboration while increasing dependency on the wireless network.
Furthermore, more services are migrating to the cloud in order to increase productivity. Due to the centralised nature of these cloud services, a new reliance on the network for high bandwidth and low latency has emerged. In the not-too-distant future, we’ll see even more integrated experiences through augmented, mixed, and virtual reality, requiring even more bandwidth and lower latency.
Another Wi-Fi 6E application case is industrial IoT, such as healthcare. Robots and self-driving cars, sensors, next-generation XR devices, cameras, humans, and objects are all vying for a piece of the spectrum in these environments. Collisions and less-than-ideal conditions are possible since these technologies typically require ultra-low latency (1–15ms), virtually no jitter, and extremely high dependability.
The concerns mentioned in the previous scenarios, as well as many more, are addressed and resolved by Wi-Fi 6E. With the 6 GHz spectrum, we get more bandwidth, lower latency, and, maybe most importantly, cleaner air.
AFC PROVIDES EXTRA POWER FOR WIDER USE CASES.
It is worth mentioning that the 6GHz band did not lack frequencies. The 6 GHz frequency has been used by incumbents for microwave and satellite communications for decades. The FCC must protect existing users while allowing Wi-Fi to’share’ the spectrum. Engineers set out to design an inside lighting system that would use less electricity and would not interact with existing outdoor systems. This is known as Indoor Low-Power (LPI).
The good news is that LPI is projected to work at the existing AP density, which eliminates the need to re-cable your building. There are, however, a number of applications that might benefit from higher, or “standard,” power. There is now a lot of work being done on a solution known as AFC (Automated Frequency Coordination). This is a centralised database of existing incumbent sites that is constantly updated as new towers or dishes are installed and contains spectrum usage information. To use ordinary electricity indoors or outdoors, the AP must first contact the AFC to determine whether power is available at the AP’s location.

The upgrade from Wi-Fi 5 to Wi-Fi 6 was large enough to pique most people’s interest. The transition from Wi-Fi 5 to Wi-Fi 6 was large enough to pique the interest of the majority of people. This protocol exceeds previous protocols by leaps and bounds in terms of stack capabilities. Wi-Fi 6E uses the same Wi-Fi 6 protocol set as Wi-Fi 6, but with more available spectrum. It allows Wi-Fi networks to accommodate higher densities with more channels, which results in fewer collisions and a better user experience. In addition, we strengthened security by implementing WPA3 standards.
