Wi-Fi 8 will not increase speeds. He will focus on something much more important
Although the Wi-Fi 7 standard has not yet become a permanent fixture in our devices, manufacturers are already preparing Wi-Fi 8. This time, the changes will not focus on increasing the transfer speed.

Subsequent versions of the Wi-Fi standard have accustomed us to the fact that they gradually increase the maximum transfers that can be achieved. However, with Wi-Fi 8 it will be different. The speed will not increase, but the reliability of the connection will improve.
Wi-Fi 8 is coming. What will change?
Information about Wi-Fi 8 appeared in MediaTek documents. At first glance, it may seem that the new standard does not differ much from Wi-Fi 7. It will use the same 2, 4, 5 and 6 GHz bands, the same modulation (4096 QAM), eight spatial streams, MU -MIMO, multiple OFDMA and maximum channel bandwidth of 320MHz.
So what will change? From the MediaTek document we learn that in the case of Wi-Fi 8, the focus was on improving performance. One of the new products will be Co-SR, i.e. Coordinated Spatial Reuse. The feature allows access points to dynamically adjust and coordinate power levels based on the distance between devices and other access points to maintain appropriate signal strength. According to MediaTek, this improves performance by 15-25 percent.
Another novelty is Co-BF, i.e. Coordinated Beamforming. This technology allows the system to avoid sending signals to areas and devices that do not need it, reducing interference and concentrating the signal towards active devices. This, in turn, is expected to improve efficiency by up to 20-50%. in networks with many devices.
On the other hand DSO (Dynamic Sub-Channel Operation) allows the network to assign subchannels based on device requirements and capabilities, which in some situations improves throughput by up to 80 percent. However, it will still be some time before we see Wi-Fi 8 devices in our homes. The standard is not expected to be ready until 2028.
