The WiFi 6 is increasingly present in the industry, since all practically all the new devices of the last year already incorporate this connectivity.
The next step is going to be the WiFi 6E, compatible with the 6 GHz band to offer even more speed, but the industry is already working on WiFi 7, the next evolution of the standard.
The name of WiFi 7 is not final yet, as the standard is still being designed under the name 802.11be Extremely High Throughput (EHT). However, it is most likely that this is the final name of a standard that is expected to reach 30 Gbps speed, in addition to using the 2.4 GHz, 5 GHz and 6 GHz bands. The most conservative estimates speak of that the speed is going to be doubled with respect to WiFi 6.
WiFi 7 will allow you to connect to several routers at the same time
To achieve these speeds, the new WiFi standard will be able to use several access points at the same time. With this, you can, for example, connect to two Internet connections with two different WiFi access points, such as two routers within the same home to achieve even higher speed without having to change the name of the WiFi network.
The technology that will allow this is CMU-MIMO, where the C is for "Coordinated". Instead of 8 data channels that WiFi 6 allows, we can have up to 16 different data channels, which can come from several access points at the same time. This is ideal for connecting in public areas, such as accessing Wi-Fi at the airport.
Thus, although the standard is not expected to be finalized until at least spring 2024, manufacturers Qualcomm, Broadcom and MediaTek are already developing chips with this connectivity. In the words of Qualcomm, the company states that it will take at least 2 or 3 more years to reach the market, so it will coincide with the final approval of the standard.
Bandwidth needs continue to advance by leaps and bounds, and WiFi standards have to implement solutions to allow it. Among the improvements that have been included in recent years, we find QAM, which has allowed the data to be better compressed to take advantage of each sending of information between the access point and the devices.
320 MHz blocks and speed up to 30 Gbps
In addition, the number of channels and frequency blocks has been increasing, with blocks of up to 160 MHz. The last big step will be the use of 6 GHz to enjoy new blocks of up to 320 MHz, as well as being able to use all frequencies. at the same time to add spectrum. Spectrum efficiency will also be higher thanks to the use of 4096QAM, compared to 1024QAM used as modulation in WiFi 6 today.
