What is WiFi 7? Certified mobile phones and why you should not worry

It happens with all mobile connectivity systems, both with 5G (or its successors) and with WiFi 7: as soon as they come out we are bombarded with their advantages and what we miss if we are not connected to this new standard. Without critical thinking involved and without seriously thinking about the advantages and capabilities of the new system. Therefore… What is Wifi 7 and why you shouldn’t worry so much?

Last week, during CES, the WiFi Alliance announced that it had begun certifying WiFi 7 devices. It should be noted that Not having this certification does not mean that a device will not workonly that its properties have been confirmed and that it is compatible with other WiFi devices.

WiFi 7 connectivity, as its name suggests, is only useful for those moments in which we connect to a WiFi network: if we are connected to an antenna from our operator, it does not matter if we have WiFi 5, 6 or 132. Therefore therefore, his Use is limited to these specific circumstances and times.

In the seventh evolution, several connectivity aspects have been improved. For example, the use of channels is expanded and we go from the 11 channels supported by the 20 megahertz (MHz) band or the 45 5 GHz channels to the 320 MHz channel width of WiFi 7, this figure indicates the width of the channel and it is like a river: the bigger it is, the more information it can transmit.

To this WiFi 7 adds Multilink Operation (MLO). Basically, this allows several band frequencies to be combined depending on the use we give it. At home, when we are connected to our router, it serves as a link to mobile phones, tablets, smart home devices, etc. The new standard evaluates the connectivity needs of each device and not only gives priority to the most “needy” ones, it also allows combine different bandwidths on the same device to reduce latency, for example, if we are using a video game with virtual reality.

Therefore, it is true that WiFi 7 offers numerous improvements, but only in certain very precise environments and we don’t have to worry if our devices are not yet certified for it. In fact, very few have already been certified. For example, the Dimensity 9200 or the Snapdragon 8 Gen 3 microchips are already prepared. Like the Oppo Find The same will happen with most smart devices introduced this year.

The same goes for laptops that will have certified microchips. Something that does make sense, considering that 99% of the time we use them with a WiFi network. Therefore, if you have a mobile phone that is not yet certified for WiFi 7, the reality is that, For now, you don’t miss anything: Don’t go running out and buy the latest model.
