We can say that PLCs are very useful devices to be able to surf the Internet and improve coverage. They are a good option to end a dead zone, where the signal does not arrive or arrives so weak that we practically cannot surf the net. However, not all models are the same and you may need a specific option. Can we use the PLCs both by Wi-Fi and by cable? We talk about it in this article.
Wireless and wired connection for PLC
PLC devices are generally composed of two devices. Each of them will be connected in a different place in the home and always connected to an electrical outlet. In addition, one of them, the one that receives the signal, will also connect to the router. In this way the connection will travel through the power line.
Now, can we connect devices to the PLC that we put in another place only by cable or is it also possible by Wi-Fi? Here you must bear in mind that not all are the same and you will find models that only work wirelessly, only by Ethernet cable or, in the most optimal case, both by Wi-Fi and by cable.
Therefore, we can say that you can connect wirelessly and by cable through the PLCs. Of course, you must make sure that you have purchased a compatible model , which allows connection by both Wi-Fi and Ethernet. There are some devices, such as a mobile phone, that will only be able to connect wirelessly. Others, on the other hand, will also be able to access via Ethernet and it will even be a better option, such as a computer or a television.
When to connect PLCs by cable and when by Wi-Fi? This question will depend on each case. In general terms, we can say that the ideal, whenever possible, is to connect your devices through an Ethernet cable. In this way you will have greater stability and also speed. You’re less likely to have problems than if you’re connected via Wi-Fi, as wireless can have more interference and issues.
Choose the PLC well
Something very important is to correctly choose the PLC devices that you are going to use. Not all of them will have the same characteristics, since there are very different models. You will find notable differences in terms of speed, coverage or the possibility or not of using Gigabit Ethernet cables and not being limited only to Fast Ethernet.
Ideally, you should buy a model that has dual-band Wi-Fi , to be able to use both 5 GHz and 2.4 GHz, as well as have compatibility with Gigabit Ethernet and be able to reach up to 1000 Gbps per cable and not be limited to 100 Mbps. In this way you will be able to make the most of the Internet rate you have contracted and you will be able to connect devices without problems to the PLCs.
In short, as you can see, PLC devices can work both by Wi-Fi and by cable. You’ll find models that work wireless only, wired only, or both. The ideal is to choose the PLC well and thus avoid problems, since the objective is to achieve maximum speed and signal quality.
