Many individuals use at home a Internet box. These enclosures all-in-one indeed allows to replace the combo “Modem Router Classic” usually necessary to access the Internet while facilitating the maximum possible use for the user…
But in US prémâchant the work to make the Wi-Fi connection always more simple and intuitive, the manufacturers of box would not be in the process of sacrificing safety and performance on behalf of the simplicity of use?
I speak to you today of the Beamforming technology, that are often found on the latest models of Wi-Fi routers but on no box ISP for the moment…
How It Works The Wi-Fi?
We all use daily, and yet only little people are really interested in the way of Wi-Fi networks.
I propose to you to discover in a few words the broad lines of the history of the Wi-Fi technology and especially its antennas because that is what is going to be of interest to us by the Suite!
Created in 1997, the first standard Wi-Fi allows a computer to communicate with another remote station wireless.
From 1997 to 2014, Wi-Fi standards evolve, allowing a flow more top and a range of signal always longer.
In 2006 appear the first antennas mu-MIMO with the 802.11n standard. These antennas ” Multi-Users Multi-outputs Multi-inputs” allows the router to forward data to several users simultaneously. Up to now the routers could not only communicate with a device connected to the time, making wait the other the time to finish the communication with the precedent.
This is the revolution of 2006 of which it will be discussed in this article, because it is this innovation which has helped to give birth to the technology” beam-forming”.
What is the beamforming?
The “Beamforming” or “beam forming” in French is a technology that allows you to use the Wi-Fi Antennas ” Mu-MiMB” (Multi-Users, Multiple-Inputs, Multiple-Outputs) to concentrate the broadcast waves in the direction of the connected device…
To make more simple, these antennas are capable of giving a “direction” to the signal and thanks to the latest Wi-Fi standards, it is possible for the router to detect where is physically located a device connected to the network.
With these two crucial information, it becomes very simple for the router to identify the user and to orient the signal of all antennas at the same time toward the latter for booster the Wi-Fi signal. With all the antennas headed in the same direction, the Wi-Fi signal is much more stable (less of packets lost during the emission) and it goes further (scope of the Wi-Fi signal greatly improved).
