What sidelines do cell phones have and what is their real function? – Teach me science

Have you ever wondered why there are lines on the sides of cell phones? Contrary to what one might think, it has nothing to do with the aesthetics of the device, so let's see what this curiosity is.

Mobile devices are a tool in our daily lives, something that, even if we resist it, is an essential part of communication between you and your loved ones, friends, or colleagues at work or school.

Since these small devices began to exist, they have not stopped making modifications and updates that provide us with more benefits as days go by.

Mobile phones have changed internally and externally, and improvements have been observed in both aspects; HD camera, more storage capacity, mobile data, touch screens, vivid colors, goodbye keyboard! Unimaginable designs, details we didn't know had a specific function like lines.

We will focus on these last details specifically on this occasion. Have you noticed the lines on the sides of some mobile phones? It's not just a look, it has a function for our device, so find out what it is.

These lines are generally placed at the top and bottom of our devices, just above where the volume up or down buttons are, and at the bottom where the SIM compartment is.

First off, the sidelines are meant to provide greater coverage, i.e. get better range from Wi-Fi and Bluetooth (if used), as well as other data networks.

Sharing the Internet on another mobile phone will also benefit from the simple fact that your mobile device has these sidelines.

Do you remember that when you first had cell phones, calls were difficult to hear or there were times when you heard a strange noise? Well, guess what, calls will be heard much better than previous cell phones or any other current cell phone that does not have this “design”, because it also does a better signal job and without interference.

Apparently they have the great “additional advantage” of giving our devices a more beautiful and sophisticated view.

Now you know that this is why you have lines on the sides of your cell phone, and it's not just for aesthetics.

It is worth noting that not all mobile phones today contain these lines, but only the newer and higher-end models.

If you know someone who has the same doubt about these strange rays, tell them what you just learned today, we are sure you will remove a huge unanswered doubt from them.

And last but not least, the use of both these mobile devices and any other devices; Laptop, computer, tablet etc. should be used with utmost responsibility.
