Tuya Smart Releases the First IoT Application Terminal Wi-Fi 6 Module

“Subsequently, Electronic products such as “Wi-Fi 6 router” and “Wi-Fi 6 wireless network card” have sprung into the market like mushrooms after rain. “Higher throughput”, “stronger anti-interference”, “more secure”, these advantages occupy major news headlines for a while, and for ordinary consumers, owning a Wi-Fi 6 device is the most intuitive experience, but It’s just that the internet speed is getting faster.

“

For most people, the first time they heard about Wi-Fi 6 was probably 2019. That year, the flagship phones of major mobile phone brands invariably put out the same slogan “supporting the Wi-Fi 6 standard”.

Subsequently, electronic products such as “Wi-Fi 6 router” and “Wi-Fi 6 wireless network card” have sprung into the market like mushrooms after rain. “Higher throughput”, “stronger anti-interference”, “more secure”, these advantages occupy major news headlines for a while, and for ordinary consumers, owning a Wi-Fi 6 device is the most intuitive experience, but It’s just that the internet speed is getting faster.

However, if only a little faster, the new Wi-Fi 6 is just a daily update compared to its predecessors. It’s like the flagship phones that come out every year – each generation has improved, but the difference in use is not that big.

But what many people don’t know is that the changes brought about by Wi-Fi 6 are creating huge waves in the field of Internet of Things (IoT).

On February 5, 2021, Tuya Smart, an AI+IoT leader, released the world’s first Wi-Fi 6 module for IoT terminals – Tuya AXBU module. Different from IoT modules based on router chips, Tuya Smart AXBU modules are the first IoT Wi-Fi 6 modules that can be mass-produced. The birth of this module marks a qualitative leap in the connectivity performance of IoT devices.

It sounds a bit vague. In terms of application scenarios, what improvements can this new module bring to IoT devices?

Equipment capacity ‘super-doubling’

In actual use, the module based on the Wi-Fi 4 communication protocol can connect 20 IoT devices at the same time. It seems to be enough at this stage, but with the rapid development of IoT technology and the growth of market demand, the number of smart devices in the home will far exceed this number in the future, and public places such as hospitals, schools, office buildings, etc. Thousands of IoT terminal devices. In order to lay out this requirement in advance, the Tuya AXBU module has increased the number of devices connected at the same time by 8 times through the improvement of Wi-Fi 6 in terms of device capacity and throughput, achieving a 100ms response time, and a single router can stably connect more than 160 IoT devices equipment.

Technically, the AXBU module uses the OFDMA multi-user frequency division multiplexing mechanism to increase the total throughput in dense environments by 3 to 4 times. At the same time, the module also introduces BSS coloring technology to identify overlapping basic service sets (OBSS), reduce co-channel interference, and increase device capacity by 4 times in dense environments.

“Unhindered” data transfer

It has been more than 10 years since Wi-Fi 4 was born, and the anti-interference ability, security and transmission speed have been unable to meet the needs of the rapid development of communication technology. And the frequency band used by Wi-Fi 4 is already very crowded in densely populated areas, and Wi-Fi 5 is relatively weak in scenarios where multiple devices are connected at the same time. In Contrast, the maximum transmission rate of Wi-Fi 6 reaches 9.6Gbps, which is 3 times that of Wi-Fi 5. The coverage frequency band is 2.4/5GHz, and it completely covers low-speed and high-speed devices.

These advantages of Wi-Fi 6 can be fully utilized in the face of high-density, large-scale IoT smart scenarios. The data rate of Tuya AXBU module reaches 229.4 Mbps, which is 52% higher than that of Wi-Fi 4 module.

In addition to the transmission speed, Tuya AXBU module has also improved in terms of device communication distance and anti-interference. The indoor OFDM mode communication distance of the module is doubled compared to that of the Wi-Fi 4 module, the anti-multipath delay expansion capability is increased by four times, and the longest communication distance is more than 300 meters.

By improving the transmission speed and transmission distance, AXBU provides a strong guarantee for more advanced and complex IoT device communication. The advantages brought by lower latency and stronger anti-jamming capabilities will be directly reflected in high-density smart scenarios.

Equipment power consumption “falls off a cliff”

No matter how advanced IoT devices or how perfect smart solutions are, one topic cannot be avoided – cost. In the process of using IoT devices, the most direct cost is power consumption. In the face of a house full of tall Powered by Tuya products, in addition to sighing, consumers’ most direct question is: How much electricity does it cost?

Another core advantage of Wi-Fi 6 is ultra-low power consumption. In a multi-user scenario, the power consumption of the Tuya AXBU module is only one-third of that of the Wi-Fi 4 module. This is mainly due to the module’s TWT technology, which significantly reduces power consumption in actual usage scenarios by reducing wake-up time.

Specifically at the product level, the same smart door lock can double its battery life by reducing power consumption after using the Tuya AXBU module. The significant reduction in power consumption also saves consumers a lot of equipment maintenance costs.

As the first mass-produced IoT terminal Wi-Fi 6 module, Tuya AXBU module undoubtedly has high expectations. It is foreseeable that the changes brought by Wi-Fi 6 will not only be limited to the improvement of device network speed, but will also bring new opportunities to the entire IoT field. Based on the new industry standard brought by Wi-Fi 6 technology, it will bring a smoother user experience, more efficient work efficiency and stronger communication security.
