The evolution of the WiFi connection has been by leaps and bounds. However, this technology still has a long way to go. If right now we can enjoy almost 10 Gbps speed through a wireless network, the truth is that WiFi 7 will be even faster.
Not only do you have to consider speed, but this connection will change everything. For this reason, we are going to review the 7 innovations that the WiFi 7 network represents for the future. And it is that, in a matter of months, this new standard will be present with all the lay in the device market.
All the changes that WiFi 7 brings
Many will wonder if it is really worth continuing to evolve WiFi networks, and the answer is yes. More than anything, because we need a series of improvements, especially in speed. This is because we will be consuming more and more bandwidth. In any case, let’s see the 7 innovations of WiFi 7 :
- PHY EHT
One of the first points in which this standard will innovate will be when it launches a new plot. Specifically, the PHY EHT will give us compatibility for tomorrow with changes that are going to occur in the frame formats and transmission opportunity. And not only this, but it will be easier to support multiple PHY frame formats within a single WiFi network.
- MLO
Thanks to Multi-linl Operation, also known as MLO, devices are capable of transmitting or receiving/sending information through different channels simultaneously. In this way, one of the first changes is that latency and congestion are reduced .
- Double the bandwidth
Another important detail is that it doubles the bandwidth. With WiFi 7 there will be a maximum channel width of up to 320 MHz , taking into account that with WiFi in the 6 GHz band, a maximum of 160 MHz is achieved, it doubles.
- Multi-AP
Another important innovation brought by this new standard is Multi-Access Point Coordination , or Multi-AP. Basically, thanks to the coordination between the neighboring access points, a significant improvement in the use of resources, spectrum, performance, latency and reliability will be achieved.
- More MU-MIMO antennas and improved OFDMA
With WiFi 7, the number of MU-MIMO antennas will be up to 16, while OFDMA (Frequency Division Multiple Access) will be better. First of all, by having a signal with less noise, we will be able to modulate to 4096-QAM. So, in this case, we will get the speed increase that we will see later. In addition, the best of OFDMA will increase the efficiency of the spectrum and the latency of the wireless connection can be reduced .
- Multi-RU
The limitation of sending or receiving data from an assigned resource unit that exists with WiFi 6 will not be in this new standard. With WiFi 7 we will have Multi-Ru , that is, multiple resource units (RU) can be assigned to a single user and achieve a significant improvement when sending data.
- Speed
By having a higher bandwidth, the speeds that this wireless connection will be able to offer us will no longer be almost 10 Gbps, but will be up to 46 Gbps speed . Of course, using a 320 MHz channel on 6 GHz or a 160 MHz channel on 5 GHz with 4096-QAM and 16 spatial streams.
