Introducing and supplying new technologies to the market is one issue and expanding its use is another issue. Wi-Fi 7 is the latest standard for wireless connectivity in the home and work environment that was introduced recently.
Although Wi-Fi 7 has been officially announced, it is not yet available in its final form, and some of its specifications are still in draft standards form. Of course, once this technology is perfected, there probably won’t be much difference between this version and the final versions. Meanwhile, MediaTek introduced the world’s first processor with support for the mentioned technology, and it is now available through the Dimensity 9200.
Wi-Fi 7: A big improvement over Wi-Fi 6E
As mentioned, Wi-Fi 7 is currently in the draft stage and therefore not yet mature, but the final version, which is said to arrive in March 2024, is not expected to be much different from the current version. However, MediaTek has started supporting this technology and it is possible that other products with this technology will be launched soon.
Wi-Fi 7, also known as 802.11be, has the potential to change the way home wireless connections work. This technology promises to quadruple current Wi-Fi 6E speeds and expand signal coverage areas.
written by GizchinaWi-Fi 7 will fully use the 6 GHz spectrum; As we have already seen with the upgrade from Wi-Fi 6 to Wi-Fi 6E, the width of each channel will also increase. According to the current Wi-Fi 7 specifications, these channels range from 160 to 320 MHz and may not change much after the official release. In addition, the MIMO Wi-Fi speed will be twice as high and offer a total of 16 data streams.
Wi-Fi 7 uses channels with twice the width, three simultaneous frequencies and twice MIMO to achieve speeds of 48 Gbps.
What’s new in Wi-Fi 7?
With Wi-Fi 7, the signal modulation will also change and we will have QAM-4096 and OFDMA. Intel has already announced that Wi-Fi 7 will be able to transfer 48 gigabits per second. For comparison, USB 4 offers a speed equivalent to 40 Gbps and reaches a maximum speed of less than 8 Gbps via cable.
The Wi-Fi 7 standard that some people and companies are using now calls its incredibly high speed Multi-Link Operation or MLO. This system allows the simultaneous use of 2.4 GHz, 5 GHz and 6 GHz channels through a kind of channel aggregation, and its speed will be up to four times the speed of today’s Wi-Fi 6E. In fact, it seems that this technology will be available earlier than 2024.
More bandwidth, more speed, less latency
Wi-Fi 7 is dependent on the spectrum currently used by Wi-Fi 6E and includes 7.125 GHz, or the entire 6 GHz band. In addition, improvements have been made in the bandwidth of this technology.
Network responsiveness will be one of the factors that will increase with Wi-Fi 7, as this channel aggregation ensures that latency rates are reduced by allowing data packets to be transmitted simultaneously on multiple channels. Once again, we point out that all Wi-Fi 7 capabilities will be available in 2024.
