Beamforming can make your wireless network perform better. After reading this article you will be able to decide whether you should enable or disable the beamforming options on your router. You will also be able to learn how and when to use it. This article is written in very simple words and no technical terms have been used in it. The main objective of writing this article is to make the concept of Beamforming as simple as possible.
Here understanding the science behind the router’s signal broadcaster technology is very important. Signals are sent in different directions. Needless to say that some of the signals wasted because they are sent in a direction where there is no device. Moving the antennas can solve the problem to some extent. You will notice the improvement in the performance of data sent and received by just changing the antennas. But what if you are told that software inside the router can tell you the directions of the data sent and received. In the light of this information, you will know where to move the antenna to get the best results.
Beamforming helps improve data transmission a lot. Don’t be surprised if you see don’t notice any performance boost in short range situations. It is because the signal is strong, to begin with. Short range is not ideal because of signals bouncing off objects or some other kind of physical interference.
Beamforming was initially implemented for wireless N networks. In was introduced as optional and was never enforced. The very first version of beamforming is known as Universal Beamforming or implicit Beamforming. One thing you should keep in mind is that it is a router based function. The router reads the direction of the data and then makes adjustments to its internal antenna accordingly.
Explicit Beamforming, on the other hand, requires the router and your device’s wireless adapter to come to a mutual understanding of the channel and direction of the transmission. You can say that in explicit beamforming both router and device’s wireless adapter know which direction they need to send data to. So signals are sent in one particular direction in the form of “beam”.
Beamforming On or Off?
As stated earlier, Short range is not ideal for Beamforming because of signals bouncing off objects or some other kind of physical interference. You should go for it if you have medium or big sized house. Once you have enabled beamforming, you will notice significant signal strength and there will be no more dead zones. If you reside in a small apartment, you may not get the desired results. You better test and experiment first before you decide to go for it.
Enable/Disable Explicit Beamforming
You should only consider enabling Beamforming if your device and router support 802.11AC. Don’t forget that some N devices support Explicit Beamforming but they have compatibility issues. Turn on the device to see whether you go for it or not.
You should go for Explicit Beamforming if you have AC devices. You better not consider this option for the B and G wireless devices if you have any. If you have AC device but having issues, you should disable this option.
Enable/Disable Implicit Beamforming
Implicity Beamforming is enabled where Explicit Beamforming is not applicable. You can test and experiment this option to see if it helps with your mid range signal performance.
You better keep this option disabled if you can use Explicit Beamforming. Explicit beamforming is recommended simply because of its better performance. Those who run AC and other wireless level technologies are recommended to separate the devices onto different frequencies.
