Wi-Fi 6 and Wi-Fi 6E: the keys to IoT

This expansion of IoT offers companies the opportunity to work smarter and more efficiently, while transforming industries such as manufacturing through robotization and machine learning. Globally, it helps spur innovation for “smart cities” and enables healthcare professionals to monitor and combat the healthcare crisis.

Connecting almost everything from appliances to traffic lights and beyond requires robust and reliable connectivity. Wi-Fi will play a key role for industrial IoT, providing high-performance, low-latency connectivity that can efficiently and reliably support a wide variety of use cases.

A global digital paradise

The IoT will become the cornerstone of the “smart cities” of the future, as research, planning and funding increase around the world. In smart cities, data-driven planning improves quality of life, from traffic monitoring to surveillance. The number of sectors that benefit from this digital revolution is very large, ranging from agriculture to construction and sustainable development.

The IoT also helps companies and employees embrace the flexibility of work greatly favored by the health crisis. Monitoring tools and the ability to connect from any location have contributed greatly to the success of remote work. Wi-Fi offers fast, reliable and secure connectivity that will allow you to take advantage of the full potential of IoT.

Wi-Fi 6 and Wi-Fi 6E: the recipe for success

IoT covers multiple use cases with different connectivity needs that require both high bandwidth for low power consumption and low latency. While in the past it was difficult to meet all of these requirements using just one technology, Wi-Fi 6 now makes it possible.

Wi-Fi 6 offers higher performance, lower latency and faster data speeds, which in addition to the deployment of 5G networks, allows connectivity indoors, in public places and in smart buildings, as well as in underserved areas, where 5G is a lot less efficient.

With features such as Orthogonal Frequency Division Multiple Access (OFDMA), Wi-Fi 6 can better meet the diverse needs of IoT devices.

Wi-Fi 6E extends these benefits to the 6 GHz frequency band, offering a significant increase in available bandwidth. Since all devices using the 6 GHz band are natively compatible with Wi-Fi 6, there is no need to allocate a budget to ensure compatibility. Wi-Fi 6E takes full advantage of the higher bandwidth, less congested frequency, and seven super-wide channels of the 6 GHz frequency band to deliver innovations like AR / VR, 8K streaming, and more.

Wi-Fi 6E also brings energy efficiency improvements such as Target Wake Time (TWT), suitable for highly congested IoT networks where many battery-powered devices and sensors are connected. The expansion of Wi-Fi into the 6 GHz frequency band will play a key role in supporting industrial IoT devices, with the addition of much-needed frequency bands for Wi-Fi uses.

However, not all countries take full advantage of this opportunity, which only arises when the 1200 MHz of the full unlicensed 6 GHz spectrum is available for Wi-Fi. If we are to meet the demands for connectivity, emanating from exponentially growing IoT devices, it is critical that regulators act.

Paving the way for a more secure and interoperable Internet of things

The rapid growth of IoT must be accompanied by more security efforts. New certification programs that support Wi-Fi 6 and Wi-Fi 6E standards will not only accelerate technology adoption, but will also ensure a strong level of WPA3 security and global interoperability so that IoT devices remain securely connected. .

In addition, the IEEE 802.11ah specification, which operates in a spectrum below one gigahertz, provides the low-power, longer-range connectivity needed for applications such as sensor networks and connected clothing. Its reach is greater than many other IoT technology options and offers a more robust connection in harsh environments where the ability to break through walls or other barriers are important factors to consider.

Overall, this will allow IoT players to bring secure and interoperable products to market to deliver the best experience for their customers.

The future

The IoT of the future is poised to transform the way society operates. In turn, the need for connectivity increases. Wi-Fi enhancements are expected to bring critical connectivity to this segment, but it is important that regulators recognize the limitations Wi-Fi currently faces in terms of IoT and release more frequencies so that Wi-Fi can continue to push IoT innovation. .
