Wireless connection technology is evolving at lightning speed. Only a few years ago Wi-Fi 6 started arriving in our homes, a few months later Wi-Fi 6E did, a few weeks ago we learned of its evolution called Wi-Fi 6 Version 2 and today we already have more information about its successor, which will be Wi-Fi 7.
Although some preliminary details on what this standard would entail were already published last September 2021, it is now that MediaTek has carried out the first live tests of the capabilities of a technology that intends to assume, once and for all, replacing the physical home network cables, or so the theory goes.
Faster, more efficient and with less latency
Wi-Fi 7 matches the technical version name 802.11be and promises to be much faster than its predecessors with lower latency. In theory, it could reach 48 Gbps, about four times faster than the almost 10 Gbps you can get today via Wi-Fi 6.
However, the implementation presented by MediaTek achieved speeds 2.4 times faster than Wi-Fi 6, or approximately 24 Gbps in a wireless interface capable of simultaneously using frequency bands in 2.4 GHz, 5 GHz and 6 GHz using the same number. antennas like its predecessors.
To do this, it uses technologies such as Multi-Link Operation (MLO), an aggregation that allows different channels to be used to transmit the same packets and guarantees low latency by using multiple bands at the same time and choosing the one which is the best option. in each case.
There are also improvements in signal modulation with Wi-Fi 7, supporting a maximum of 4096-QAM, also using OFDMA (orthogonal frequency division multiple access) and with maximum channel bandwidth which doubles that offered by Wi-Fi 6 ranging from 160 MHz to 320 MHz.
And why so much speed at home? Well, from MediaTek they hope that Wi-Fi 7 will become the basis for new 4K and 8K video streaming applications that are yet to come, for games with lower latency and above all to open the door in the future virtual reality and augmented reality.
As for the arrival date of the first products such as routers, network cards, mobile phones, etc., according to MediaTek, they expect the rollout to begin in 2023.
