Will super-speed WiFi launch in 2023?

WiFi 7 is developed based on IEEE 802.11be standard, operating on 320 Hz frequency channel instead of 160 Hz like WiFi 6/6E. It also supports Multi-Link Operation (MLO) technology, flexibly using all available bands and channels to speed up connections or avoid bands with high interference.

In contrast, previous generations of WiFi could only connect to devices through a single band. Users often have to connect low-bandwidth devices such as e-readers, smart thermostats through the 2.4 GHz frequency band and switch to 5 GHz when using laptops and smart TV boxes.

With MLO, WiFi 7 can scan for the best band for data transmission and intelligently switch between different bands. This helps to take advantage of multiple bands at the same time, reducing network latency because channels are not busy or congested, and data can be transmitted on demand without waiting.

And yet, WiFi 7 also has Quadrature Amplitude Modulation (QAM) technology, which transmits and receives data using radio frequency waves, helping to increase the amount of data transmitted in the network.

With the most advanced technologies, the 7th generation WiFi standard is considered a strong upgrade compared to the previous generation. The theoretical maximum data rate is close to 30 GB/s, twice as fast as WiFi 6E and three times faster than WiFi 6.

WiFi 7 will help reduce latency and instability of the network. As a result, next-generation connectivity promises to pave the way for smart home technologies such as 8K video playback, virtual reality equipment for the metaverse – which requires broadband.

To take advantage of the new features and improved performance on WiFi 7, users need to upgrade the device. That means, you need to buy a new router along with a new smartphone, laptop, TV … at a cost of up to thousands of dollars.

Forbes magazine said that at the present time, users should not spend money to buy a new WiFi 7 router because of the expensive price. Besides, users will hardly notice the change between WiFi 7 and WiFi 6 with the need to use laptops, smartphones, and tablets normally.
