Install a PLC Network to have Internet  Step by Step Guide ▷ 2020

Lately, the advances that have been generated in the field of telecommunications are absolutely remarkable. Since, progressively, they show new technologies in order to provide higher performance, better bandwidth, transmission speed, etc.

In the home environment, the most widely used local network transmission technology, is the WiFi. Mainly, for the comfort it offers compared to the use of the Ethernet cable. However, in many cases it can be inconvenient 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 arises for users to search other connection alternatives to solve these faults. Thus, currently, one of the most interesting is the Internet connection through the electrical network through a PLC And since it is a somewhat unknown solution, in this post we will indicate the most important of it.

What is the PLC and how does this type of Internet connection work?

What is the PLC

The PLC or “Power Line Communications”Refers to a type of Internet connection that basically encompasses different technologies that allow sending data transmissions through 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 telecommunications 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.

However, it is worth clarifying that the performance of the connection by PLC It will depend on the quality of the electrical signal you have at home. So, under normal conditions, it will be able to offer optimal performance.

Now, in reference to the operation of the PLC as an Internet connection, this is an aspect that develops as it is established. Well, the provider is the one who will promote the general characteristics and functions that it may have. Either, depending on the control requirements, monitoring, registration and all the aspects of greater importance when the project is in development.

However, it is appropriate to emphasize 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 to be executed. For which, it is necessary use specific software.

In such a way that, it is capable of automating electromechanical successions 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?

Is the PLC really a reliable alternative to ADSL or FTTH

Taking into account that the ADSL or the symmetric digital subscriber line changed everything in terms of Internet connections, mainly due to its easy installation and simple 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 wonder if the PCL is a reliable solution to these types of networks.

Well, it should be noted that not a truly comprehensive alternative to 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 voltageas the power 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 mentioned in this section.

Bearing 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 network of “Power Line Communications”?

First of all, if we mean 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 bearing in mind 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 inputs. So that, with this query, you can extract from the program memory all the steps to be carried out to correctly produce 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.

The input and output interfaces

They are responsible for establishing communication between the PLC device and the plant or the processes from which it can receive information and at the same time send the output signals optimally.

On the other hand, to achieve install a PLC network at home, simply 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

Secondly, a repeater is required that plugs precisely into the socket from where you want to have an Internet connection.

 What are the necessary components to create a network of "Power Line Communications"

It should be noted that, commonly, these two pieces necessary to establish an Internet connection with a PLC, are sold in a ready-made pack and are distributed by several brands. So that, you should not 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

install a Power Line network in your home

To proceed with the installation of a PLC, you must have the aforementioned devices. Which may be the most basic on the market to be able to have an Internet connection truly stable and in many cases, fast.

Thus, it should be noted that PLCs are adapters that connect to a socket and only in that 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, as the PLC device has to be connected to a socket, obligatorily; some manufacturers make sure to supply such a device with an additional plug so as not to occupy another one. Apart from it, there are also some of these devices creating a WiFi hotspot and thanks to this, it is not necessary to link it by cable.

Now, then, we indicate the steps to follow to have an Internet connection through the power grid through a PLC:

Initially connect the router to the input PLC

To start installing a PLC in the home, first of all, you must connect the device to any outlet in the place you want. This being, the entry point that It will facilitate the transfer of the Internet through the electrical network.

Regarding the main recommendations to do this, we highlight that it is extremely important connect the PLC device directly to the socket and not to a power strip that has other electrical appliances connected. Since, if you do the opposite, it is very likely that the Internet connection is of poor quality and totally unstable.

Proceed to connect the router to the PLC

After having the device in question connected to the outlet 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 box of the PLC kit that you buy from the manufacturers.

However, it is recommended use a high-speed Gigabit cable, so that the connection appears completely stable and always emits an absolutely fast operation.

In case the PLC has a WiFi connection point, it is not required to use an Ethernet cable. Well, you will simply have to link both devices with the password that the house WiFi has.

Now, bind your device to the output PLC

After specifying the above, you need to connect it to the output device. Since there is already an Internet connection in the electrical current of the house, but no receiving device is connected to it.

So, to do this, you must take whatever device 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 living room.

Once you are on site, grab the other PLC device (i.e. the output device) 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 to 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 making use of 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:

Does having more than one PLC kit installed do any good and will this improve your connection?

There is a big question mark 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 a lower network performance.

In this sense, it is appropriate to highlight that the most common PLC connection only makes use of two such devices (as we indicated in the step by step), that is, the input and output (or main and secondary). But nevertheless, there is the possibility of placing all the PLCs you want, in order to cover all the sites where you prefer to have an Internet connection.

But, when adding another PLC device to this connection, it is important to take into account one important aspect regarding the make and model of the equipment. Given that, although different brands and speeds can be used, the most appropriate thing is 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 greater coverage Y does not produce 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 appliances.
