What is Wi-Fi 7?

Wi-Fi 7 is the next generation of Wi-Fi technology, following the Wi-Fi 6 (802.11ax). Designed to meet the growing demands for faster speeds and more robust connectivity. Wi-Fi 7 is built to handle a higher number of devices, provide faster data transfer rates, and lower latency. All within an increasingly interconnected world.

Key Improvements of Wi-Fi 7

1. Exceptional Data Transfer Speeds. One of Wi-Fi 7’s standout features is its ability to provide data transfer speeds far surpassing those of its predecessors. Wi-Fi 7 can reach speeds of up to 30 Gbps, much faster than the 9.6 Gbps offered by Wi-Fi 6. This allows for rapid large file downloads, lag-free online gaming, and seamless 8K streaming.
2. Reduced Latency. With a technology called Multi-Link Operation (MLO), Wi-Fi 7 drastically reduces latency by enabling devices to connect simultaneously across multiple channels. This feature is particularly beneficial for real-time applications like online gaming, video conferencing, and virtual reality, where low latency is crucial for an optimal user experience.
3. Optimized Channel Usage. Wi-Fi 7 can utilize wider channels, up to 320 MHz, compared to the 160 MHz supported by Wi-Fi 6. This expanded bandwidth ensures faster and more stable data transmission, especially in high-density environments like offices or stadiums, where many devices are connected at once.
4. Improved Support for Multiple Devices. As the number of connected devices continues to surge in homes and businesses, Wi-Fi 7 has been specifically designed to handle environments with high device density. The Orthogonal Frequency Division Multiplexing (OFDM) technology allows for better interference management and guarantees higher-quality connections, even with numerous devices connected at the same time.

Wi-Fi 7 in Everyday Life

Wi-Fi 7 is poised to transform many aspects of our daily digital lives. Here are a few concrete examples of improvements you can expect:

• Ultra-High Definition Streaming: Wi-Fi 7 will make 8K streaming services and virtual reality more accessible, without lag or quality degradation.
• Gaming and Real-Time Applications: Reduced latency and better channel management will provide a much smoother online gaming experience, crucial for both professional players and competitive gaming enthusiasts.
• Remote Work and Video Conferencing: Wi-Fi 7 will optimize connections during online meetings, offering superior stability and video quality, even in environments with high device density.

Wi-Fi 7 Deployment: Available in 2025

Wi-Fi 7 is starting to roll out in 2025. Several manufacturers have already announced devices compatible with this technology, and Wi-Fi 7 routers are available on the market. However, large-scale deployment will take some time as consumers and businesses adopt this new standard for both home and professional equipment. The infrastructure needed to fully support Wi-Fi 7 will continue to expand, and widespread adoption will likely occur in the coming years.

Wi-Fi 7 represents a major leap forward in wireless networks. With incredibly fast speeds, ultra-low latency, and enhanced support for multiple devices. This new standard will meet the growing connectivity needs in an ever-evolving digital world. While it is already accessible for some devices in 2025, mass adoption will take time. However, it is clear that this technology will dramatically transform how we live and work online.

An Innovative Design with Impressive Performance

Electric motors have long been integrated into the axles of cars. But the idea of a motor located directly within the wheel is a major advancement. Donut Lab unveiled its second generation of wheel-integrated electric motors, featuring a unique ring-shaped design. These motors boast exceptional characteristics, including a power output of 630 kW (845 horsepower) and an impressive torque of 4,300 Nm per unit. This configuration eliminates the need for a traditional transmission system, freeing up valuable space within the vehicle’s chassis. Thus, it opens up new possibilities in terms of design and performance.

Weight Reduction and Increased Range

One of the greatest advantages of this motor is its lightweight nature. Weighing only 40 kg per unit, it is about three times lighter than a traditional electric motor. This weight savings, combined with the removal of components such as the transmission, reduces the overall mass of the vehicle, thereby increasing its energy efficiency and range. However, the integration of the motor into the wheel results in an increase in unsprung mass, which could affect handling and ride comfort, especially during braking. Manufacturers will need to find solutions to compensate for this effect while maintaining the overall performance of the vehicle.

Democratizing Electric Vehicles: A Matter of Cost

The Donut motor stands out not only for its performance but also for its reduced manufacturing cost. Donut Lab claims that this motor is 50% cheaper to produce than conventional motors, thanks to the reduction of nearly 120 parts. This cost savings could lead to less expensive electric vehicles, making these technologies more accessible to a broader audience. This reduction in costs also comes with greater design flexibility. The space freed up by integrating the motors into the wheels could be used for larger batteries, spacious interiors, or innovative aerodynamic solutions.

Outlook and Challenges for the Automotive Industry

While the concept of wheel-integrated electric motors is promising, several technical challenges remain. One of the main obstacles is the increase in unsprung mass, which can impact ride comfort and vehicle dynamics. Solutions, such as the adoption of adaptive suspensions, are being considered to mitigate these effects.

Manufacturers like Kia-Hyundai are also exploring wheel motors that incorporate suspensions. This shows that the automotive industry is increasingly interested in this technology. Nonetheless, Donut Lab has yet to announce a commercialization date or any clients that have adopted this innovation. This leaves an uncertain future for this technology.

The Donut motor from Donut Lab represents a significant advancement in the automotive industry. Offering exceptional performance, reduced manufacturing costs, and greater design flexibility. If this technology becomes mainstream, it could transform the electric vehicle industry. Making these vehicles more affordable while improving their efficiency. However, technical challenges remain, and it will take time for this innovation to be fully embraced by manufacturers to measure its impact on the market.
