Lately, the advances that have been generated in the field of telecommunications are quite remarkable. Since, progressively, they show new technologies in order to provide higher performance, better bandwidth, transmission speedetc.
In the home environment, the most widely used local network transmission technology, is the Wi-Fi. Mainly, for the comfort it offers compared to the use of the Ethernet cable. However, on many occasions it can cause problems due to interference or lack of coverage. But although the ethernet it can be more reliable, its installation is much more tedious.
Given this, the need for users to search for other connection alternatives to solve these faults. Thus, currently, one of the most interesting is the Internet connection through the electrical network. via a PLC and since it is a somewhat unknown solution, in this post we will tell you the most important thing about it.
What is the PLC and how does this type of Internet connections work?
The PLC or “Power Line Communications” refers to a type of Internet connection that basically encompasses different technologies that allow data transmissions to be sent via power line. In this way, making use of this new technological concept, it is possible to make use of the domestic electrical installation as a telecommunication infrastructure.
Therefore, it will not be necessary to depend on the instability shown by the WiFi service to which you are affiliated and you will not have to carry out an Ethernet cable installation that is truly expensive, both at home and business level.
However, it is valuable to clarify that the performance of the connection by PLC It will depend on the quality of the electrical signal you have at home.. Therefore, under normal conditions, it will be able to offer optimum performance.
However, in reference to the operation of the PLC as an Internet connection, this is an aspect that is developed as it is installed. Well, the provider is the one who will promote the characteristics and general functions that it may have. Either, depending on the control requirements, monitoring, registration and all the most important aspects when the project is in development.
However, it is worth noting that a PLC is a kind of computer that must have with certain components that we will detail throughout the post and once these are connected correctly, you have to do a programming prior to the function that is going to be executed. For which it is necessary use specific software.
In such a way that it is capable of automating electromechanical sequences and executing an action depending on the signal it receives from another process, basically.
Is the PLC really a reliable alternative to ADSL or FTTH?
Taking into account that ADSL or the symmetrical digital subscriber line changed everything in terms of Internet connections, mainly due to its easy installation and easy deployment by using the same infrastructure as the telephone line.
Like, fiber optic direct to the home or FTTH that offers connections much higher, thus optimizing the experience in the networks; You will wonder if PCL is a reliable solution for these types of networks.
Well, it should be noted that not a truly comprehensive alternative given the performance that both ADSL and FTTH have shown over the years. Because, despite the fact that it is a technology designed to simplify Internet connections, It can also present different problems.
Among these drawbacks, we highlight that there is the possibility of overcome the steps from high voltage to medium and low voltage, since the electrical supply must be used. In addition to this, it can also cause certain interferences and this makes it an unhelpful method compared to the recognized types of connections named in this section.
Keeping in mind that, in general, the PLC is simply profitable to bring the Internet to rural areas and thus, it is considered ideal for small population centers.
What are the necessary components to create a “Power Line Communications” network?
First of all, if we refer to the internal components of a PLC, are different from those required to create an Internet network of this type. Well, beyond the PLC device, it requires others to establish communication correctly. However, it is worth noting What is the internal architecture of a PLC.
Next, we detail its parts:
The central processing unit or CPU
refers to the block in charge of verifying the status of the tickets. So that, with this consultation, it can extract from the memory of the program all the steps to carry out to elaborate, in a correct way, the output signals.
an internal memory
It is a memory that is responsible for maintaining the data that arise and are managed during the intermediate processes. Which are translated and cannot be seen reflected in the output.
input and output interfaces
They are those that deal with establishing communication between the PLC device and the plant or processes from which it can receive information and, at the same time, send the output signals in an optimal way.
On the other hand, to achieve install a PLC network in the homesimply two elements are required and these are indicated below:
an adapter
Basically, it is the device that connects to the electrical signal where the router is also connected that provides the Internet throughout the house.
a repeater
In second place, a repeater is required that plugs right into the socket from where you want to have an Internet connection.
It should be noted that, commonly, these two pieces necessary to establish the Internet connection with a PLC are sold in a ready pack and are distributed by various brands. So that, you will not have to buy the adapter and repeater separately.
Steps to install a Power Line network in your home and amplify your Internet connection using the electrical network
To proceed with the installation of a PLC, you must have the aforementioned devices. Which can be the most basic on the market to be able to have an Internet connection truly stable and in many cases, fast.
Thus, it is necessary to highlight that PLCs are adapters that are connected to a socket and only in this way, can send the internet signal to another adapter that is in another outlet in the home. Therefore, the two devices to be used must have an Ethernet port so that you can connect the router on one side and the computer on the other.
However, since the PLC device has to be connected to a socket, it is mandatory; some manufacturers make sure to provide such a device with an additional socket so as not to occupy another one. Apart from it, there are also some of these devices that create a WiFi hotspot and thanks to this, it is not necessary to link it by cable.
Now, here are the steps to follow to have an Internet connection through the electrical network through a PLC:
Initially, connect the router to the input PLC
To start installing a PLC at home, first of all, you must connect the device to any socket in the place you want. This being the point of entry that will facilitate the transfer of the Internet through the electrical network.
Regarding the main recommendations to do this, we emphasize that it is extremely important connect the PLC device directly to the socket and not to a power strip have other electrical appliances connected. Since, if you do the opposite, it is very likely that the Internet connection will be of poor quality and totally unstable.
Proceed to connect the router to the PLC
After having the device in question connected to the outlet that you have preferred to use, it is necessary that connect the router to the PLC via an Ethernet cable. These are usually included in the PLC kit box that is purchased from manufacturers.
However, it is recommended use a high-speed gigabit cableso that the connection appears completely stable and always emits absolutely fast operation.
In case the PLC has a WiFi connection point, it is not required to use an Ethernet cable. Well, you just have to link both devices with the password that the home WiFi has.
Now, bind your device to the output PLC
After concretizing the above, it is necessary to connect it to the output device. In view of the fact that there is already an Internet connection in the electrical current of the house, but there is no receiving device connected to it.
So, to do this, you must take any device that you want to connect to the network (the computer, for example) and go to the room to which you need move internet signal. Like, for example, the room.
Once you are at the site, take the other PLC device (i.e. the output one) and proceed to connect it to a socket again. At this point, it is also advisable to do it directly to the plug and not use a power strip.
Finally, repeat the process you did with the router. But, in this case, you have to link your computer or any device to the PLC using an Ethernet cable and this should be enough to have an Internet connection in seconds.
Next, a brief diagram in which you can see how to connect to the Internet with a Power Line Communications:
Is there any use in having more than one PLC kit installed and will this improve your connection?
There is a big question regarding installing more than one PLC kit in the home. Since users do not know if this could optimize the Internet connection or, on the contrary, generate interference that causes lower network performance.
In this sense, it is worth noting that the most common PLC connection only makes use of two such devices (as we indicate in the step by step), that is, the input and the output (or main and secondary). Nevertheless, there is the possibility of placing all the PLC you wantin order to cover all the places where you prefer to have an Internet connection.
But, when adding another PLC device to this connection, it is important to take into account a relevant aspect regarding the make and model of the computer. In view of the fact that, although different brands and speeds can be used, it is best to use the same models and manufacturers to prevent performance and timing issues.
All this means that having more than one PLC kit installed in the home can be supported for generate more coverage Y does not cause interference on site. Taking into account that, generally, these interferences occur when you use electrical appliances with powerful motors and for this, it is advisable to place the PLC in a connector further away from these devices.
