If you have never heard of this term, we are here to help you out. Beamforming is a technology that focuses mainly on wireless signals that are pointed towards a specific receiving device.
This is in comparison to other signals that spread in all directions and are usually broadcast using an antenna. The result of this specific device targeting is that it makes it faster, stronger, and much more reliable compared to the common Wi-Fi systems.
Although the concept behind beamforming has been around for a long time, it is in recent years, that it has been introduced in order to improve on what the normal Wi-Fi systems have to offer. In today’s world, it is a crucial technology for the 5G network. Read on to learn more about it.
How Does Beamforming Create Wireless Connections?
In the normal systems, a single antenna is usually used to broadcast a wireless signal that in turn radiates in many directions – unless you have blocked it by use of an object. This is the nature of how electromagnetic waves usually work.
Now, if you want to focus the signal to just one direction, then you shall be required to form a targeted beam of electromagnetic energy. This technique requires you to have multiple antennas in close proximity. All of them should broadcast the same signal at different times.
The overlapping waves produce interference in some areas, which is constructive interference, and this will make the signal very strong. If executed in the right way, beamforming can focus your signal to where you want it to be.
Benefits of Beamforming
When you focus the Wi-Fi signal to just one specific direction, you allow the signal to be of high quality to the receiver. This in practice means that the information you shall be transferring shall have very few errors, and you will not need to boost the broadcast power.
This is actually the holy grail of having a wireless network. The goal of most of the techniques actually improves wireless transmissions.
Additionally, because you are not broadcasting the signal in many directions, beamforming reduces the interference that most people experience especially when looking for a signal.
Limitations of Beamforming
The limitations of this technique includes the computing devices it requires. In most scenarios, the time and power resources you need, while beamforming will end up negating all of the advantages we have outlined above.
However, there have been some continuing improvements in the PCs, and efficiency of power that is making beamforming more affordable for building a consumer network.
This technology first appeared in routers in 2008, which was when the router 802.11n Wi-Fi Standard was introduced. This is the first router version that supported multiple inputs and multiple output technology, and beamforming needs this in order to send multiple signals that are overlapping.
This equipment however did not take off, because the spec did not lay out how beamforming would be implemented. A few sellers put out the implementations required to purchase the matching routers and the wireless cards they would need to work.
Today, you are likely to encounter beamforming while using local Wi-Fi networks. But, the current rollout of the 5G network is likely to change things.
5G uses high radio frequencies that are between 30 and 300 GHz. This can transmit data very fast, but it is more prone to interference and also encounters difficulties when passing through physical objects.
There is a whole host of technologies that are required to overcome these problems and this includes massive MIMO, Smaller cells, and beamforming. If 5G is going to take off, then vendors shall be counting on beamforming to make things easier.
With the current changes in technology, it’s always good to keep yourself informed of the latest techniques. Beamforming is one that will make data transmission much faster, and eliminate the many interferences you experience while online.
