Wireless technology has seen significant advancements with WiFi 6, with its faster speeds, lower latency rates, and ability to accommodate an ever-increasing number of connected devices. Its successor, WiFi 7, is shaping up to become even better and could revolutionize how we access the web in future generations.
What Is WiFi 7 (802.11be)?
WiFi 7, officially known as 802.11be, is the seventh generation of wireless networking technology and builds upon its predecessor – WiFi 6 (802.11ax). WiFi 7 builds upon these foundations by offering new advances that aim to increase network performance for high-demand environments dramatically – faster data transfer speeds, increased efficiency in congested networks and enhanced user experiences across devices are just some of the goals it will support.
WiFi 7 will become widely available over time, ushering in more innovative homes, high-quality video streaming, immersive virtual reality experiences and further expansion of the Internet of Things (IoT).
Key Features of WiFi 7
1.Faster Speeds of up to 46 Gbps
One of the key advancements of WiFi 7 is its remarkable speeds – WiFi 6 offers maximum speeds up to 9.6 Gbps, while WiFi 7’s theoretical maximum of 46 Gbps is made possible by employing various new technologies like:
Wider Channels (320 MHz): WiFi 7 expands available bandwidth with wider 320 MHz-wide channels than the 160 MHz channels used by WiFi 6. This wider bandwidth enables more data to be transmitted simultaneously, significantly speeding up speeds.
1024-QAM (Quadrature Amplitude Modulation): WiFi 7 will utilize 1024-QAM technology, which enables more bits to be encoded per symbol and thus increase data throughput.
Though real-world speeds may differ, WiFi 7 will significantly boost activities that require fast internet, such as 4K/8K streaming, large file transfers and online gaming.
3.Multi-Link Operation (MLO)
WiFi 7 unveils its revolutionary Multi-Link Operation (MLO), allowing devices to simultaneously connect to three frequency bands – 2.4GHz, 5GHz and 6GHz). This breakthrough feature facilitates the following:
Use of multiple bands: By taking advantage of numerous bands, devices can combine data from various channels for faster speeds and enhanced performance.
Improved reliability: If one frequency band experiences interference or congestion, devices can automatically switch to another one to maintain stable connections.
Improved user experience: MLO provides greater flexibility for environments with heavy wireless traffic, such as offices or public spaces, by providing more reliable connections that experience fewer drops and slower speeds – even when connecting multiple devices simultaneously.
4.Increased Efficiency with OFDMA and MU-MIMO
WiFi 7 takes the efficiency features introduced with WiFi 6 to an entirely new level: OFDMA and MU-MIMO capabilities offer significant gains for improved efficiency.
OFDMA (Orthogonal Frequency Division Multiple Access): WiFi 7 enhances this technology to maximize the use of available spectrum space more effectively. OFDMA allows multiple devices to share the same channel without interfering with each other, increasing efficiency by sharing less bandwidth at once.
MU-MIMO (Multi-User, Multiple Input and Multiple Output): Multi-User Multiple Input and Multiple Output) enables a router to communicate simultaneously with multiple devices; WiFi 7 extends this technology further for improved performance in environments with high device density.
These technologies can help reduce congestion on wireless networks and improve performance, particularly in environments with many connected devices, such as smart homes, offices, or public spaces.

Increased Utilization of 6 GHz Band
WiFi 6 introduced the 6 GHz band, while WiFi 7 will improve upon it by using this high-frequency spectrum more. With less congestion than its counterparts (2.4 and 5 GHz bands), devices that use this frequency should experience faster speeds with reduced interference.
WiFi 7 will use the 6 GHz spectrum more effectively, making it suitable for demanding applications such as HD video streaming, cloud gaming, and enterprise networks.
How WiFi 7 Will Affect Different Sectors In terms of Smart Homes and IoT devices,
WiFi 7 provides the bandwidth and reliability necessary for an expanding number of connected devices in homes and businesses alike. Devices such as thermostats, security cameras, and voice assistants will enjoy enhanced connectivity and speed with greater speeds provided by this enhanced WiFi.
Gaming: WiFi 7’s low latency and faster speeds will profoundly impact online gaming, particularly cloud services like those provided by PlayStar and Battle.net. Gamers will experience seamless streaming even for high-performance titles that necessitate low-latency internet connections.
Healthcare: WiFi 7’s reliable connectivity and low latency can enhance telemedicine and remote monitoring systems, enabling real-time interaction between physicians and patients and seamless transfer of large files or images.
Video Streaming: With 4K and 8K content increasingly becoming mainstream, WiFi 7 enables users to stream ultra-HD videos without buffering or quality loss, even when multiple devices access it simultaneously.
WiFi 7 Is Coming… Although WiFi 7 has yet to be officially released, its official launch is anticipated sometime between 2024 and 2025. As with previous generations of WiFi technology, its adoption will depend on compatible hardware like routers, smartphones, laptops, and other devices.
Manufacturers are already developing devices compatible with WiFi 7. Once it is adopted as the standard, we can expect a seamless transition into faster and more reliable wireless connectivity.
Conclusion
WiFi 7 promises to be the next revolutionary breakthrough in wireless technology, offering faster speeds, lower latency times, increased efficiency, and the capability to handle more devices than its predecessor. Its speed and reliability will allow us to stream 8K videos, game online, or run smart homes—something its predecessor was incapable of.
As we look toward the future of connectivity, one thing is sure: WiFi 7 will play an essential role in keeping us all connected in ways previously thought unimaginable.
