What to expect from Wi-Fi 7?
Among the main features of Wi-Fi 7, we can expect features and improvements in:
- such as improvements in access speed;
- transmission capacity.
In this way, 802.11be technology promises advances in several fields, such as: 8k video streaming, IoT connectivity and AR/VR games.
Another important point is that, despite not yet having an exact release date, the new Wi-Fi standard will be made available to the public sometime in 2024. It is even possible to find some devices compatible with this technology, and the list promises to increase over the next year.
Regarding technical specifications, you can expect the following from Wi-Fi 7:
- Maximum data transfer speed: up to 46 Gb/s;
- Channel width: up to 320 MHz per channel
- Operating frequency: 2.4 GHz, 5 GHz and 6 GHz;
- Modulation: 4096QAM;
- MIMO: 16×16 MU-MIMO for download and upload;
- Security protocol: WPA3;
- Frequencies used: 2.4 GHz, 5 GHz and 6 GHz.

What are the benefits of Wi-Fi 7?
For those who are already looking at the new wireless connection technology, below we demonstrate the main benefits brought by this evolution. Look:
1. Connection speed
One of the main features of Wi-Fi 7 is that it has a maximum rated speed of 46 Gb/s. For comparison purposes, this value is up to four times higher in a direct comparison with that seen in Wi-Fi 6/6E.
Another important feature of Wi-Fi 7 is its bandwidth, with up to 320 MHz of spectrum per channel used. Previously, the values were 160 MHz on Wi-Fi 6/6E and 80 MHz on Wi-Fi 5.
3. Multi-Link Operation
A detail that will be very popular with some people looking at 802.11be technology is the fact that it uses Multi-Link Operation (MLO) technology. Thanks to it, devices can connect to the router using more than one frequency simultaneously with more speed and stability, as well as lower latency.
For those who always pay attention to security issues whenever a new technology is launched or announced, you can rest assured: Wi-Fi 7 allows WPA3 standard encryption. In Wi-Fi 5 and earlier, the default was WPA2.
Check the comparison between connections
For those who like to analyze some more technical aspects of connections, we will show in the table below the differences between Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E and Wi-Fi 7. Check it out below:
Connection type – WiFi 5 | Wi-Fi 6 | Wi-Fi 6E | WiFi 7
Release year – 2013 | 2019 | 2021 | 2024 (expectation)
IEEE Standard – 802.11ac | 802.11ax | 802.11ax | 802.11be
Max data rate – 3.5 Gbps = 9.6 Gbps = 9.6 Gbps = 46 Gbps
Bands – 5GHz | 2.4 GHz and 5 GHz | 2.4 GHz, 5 GH and 6 GHz | 2.4GHz, 5GHz, 6GHz
Channel Size – 20, 40, 80, 80+80, 160 MHz | 20, 40, 80, 80+80, 160 MHz | 20, 40, 80, 80+80, 160 MHz | Up to 320MHz
Modulation – 256-QAM OFDM | 1024-QAM OFDMA | 1024-QAM sOFDMA | 4096-QAM OFDMA (with extensions)
MIMO – 4×4 MIMO DL MIMO | 8×8 UL/DL MU-MIMO | 8×8 UL/DL MU-MIMO | 16×16 UL/DL MU-MIMO
UK – / = RU = RU = Multi-RUs
MAC – / = / = / = MLO

What are the applications for Wi-Fi 7?
After observing all the characteristics of the Wi-Fi 7 connection, we will highlight some possible uses for this new technology.
- Video streaming: with the connection speed brought by Wi-Fi 7, it will be possible to stream 8K videos without problems;
- Virtual or augmented reality: the use of MLO technology will help reduce latency, especially when used in AR and VR applications;
- File transmission: with a nominal speed of up to 46 Gb/s, file transmission will be even faster if you decide to use the wireless network for this task;
- Online games: yet another front that will benefit greatly from the arrival of Wi-Fi 7, as the technology allows for a lower ping and also a better response time in your games;
- Commercial use: Finally, Wi-Fi 7 will also be a great ally on some commercial fronts, as it has characteristics capable of serving applications associated with IoT and even remote surgeries.
What do I need to use Wi-Fi 7?
Finally, a question that some may have is what is needed to use Wi-Fi 7. If you are interested, the technology requires the use of a router that is capable of supporting this new standard.
It is worth mentioning, however, that There are still few routers available on the market that are capable of supporting this technologybut this scenario should change from 2024. Another important point is that your device, be it a notebook or smartphone, also needs to be compatible with Wi-Fi 7.
