The new Wi-Fi 8 standard focuses on improving data transfer efficiency rather than increasing maximum speed. Key improvements include coordinated spatial utilization and dynamic subchannel management.
Evolution of Wi-Fi standards
Key characteristics of Wi-Fi 8
MediaTek has revealed information about the upcoming Wi-Fi 8 (IEEE 802.11bn Ultra High Reliability) standard. It is noteworthy that the new standard, which will replace the not yet approved Wi-Fi 7, will retain the main technical parameters of its predecessor. Final specification is expected by September 2028.
Technical Specifications
According to MediaTek, Wi-Fi 8 will retain a maximum physical layer speed of 23 Gbps (2880 Mbps x8). The standard will operate in four bands (2, 4, 5 and 6 GHz), using 4096 QAM modulation with a bandwidth of 320 MHz.
Innovative Technologies
A key innovation will be improved Coordinated Spatial Reuse (Co-SR) technology. Unlike the previous version in Wi-Fi 6, the new implementation will allow access points to coordinate output power more efficiently, increasing overall throughput by 15-25%.
Dynamic sub-channel management
DSO (Dynamic Sub-Channel Operation) technology optimizes the distribution of resources between devices with different capabilities. The system will dynamically allocate additional subchannels to more powerful devices while simultaneously downloading files.
Release timeline
Despite the long development process (about six years), manufacturers are striving to accelerate the introduction of new technologies. The first devices supporting Wi-Fi 8 are expected in early 2028.

Finally, manufacturers have stopped chasing speed and started real optimization! 🔥 Coordinated Spatial Reuse looks promising, especially for large rooms with multiple access points.
Sophie
It will be interesting to see how Co-SR will work in practice. I have three access points at home, and sometimes I have problems moving between them. 📱
Heinrich
I agree with Lorenzo! Stability is more important now than record numbers. Especially given the increase in the number of IoT devices in homes.
Viktor
They're inventing a bicycle again. Wi-Fi 6 has just started working properly, and they are already announcing Wi-Fi 8. Why does an ordinary person need such speeds? Another marketing ploy! 😤
Isabella
Sophie, I have a similar situation! I hope that Dynamic Sub-Channel Operation will really improve the experience across devices. Especially with old gadgets 💫
Lorenzo
Viktor, it's not about speed, it's about efficiency. Imagine how this will improve your smart home and streaming experience! 🏠
Heinrich
Isabella is right about DSO - it will solve the problem of compatibility between different generations of devices. MediaTek came up with a good idea! ⚡
Sophie
I can already imagine how this will simplify the work of office networks. I hope all manufacturers will have time to prepare by 2028 🌟
