Why is there no Internet connection in Metro Tunnels?

Of course, we use the internet in many ways, from answering our e-mails to video chatting. to strong networks we need.

While being underground is the biggest reason why this problem cannot be overcome, what prevents the internet from being strengthened in the underground world as well? What are the challenges?

Depth and infrastructure are among the primary challenges.

The fact that the metro tunnels are meters underground prevents us from accessing the internet. This depth makes it difficult for radio waves to reach the tunnels from the surface. concrete and metal Radio waves, which have difficulty passing through dense materials such as, cannot pass through twisting tunnels and corners.

Both engineering and money are required.

Although it is easy to install Wi-Fi in stations costly A business. Internet can be provided by placing signal-providing antennas on station ceilings or in spaces, but this is not as simple as it seems.

Cabling is expensive and it is necessary to intervene in the station infrastructure to ensure that this process is reliable and uninterrupted. For this too careful engineering condition comes before us.

Fine workmanship is required.

Leaky feeder coaxial cable In other words, thanks to the cables passing through the pipe placed in the tunnel, the signal can pass through the tunnel without the need for an antenna, but due to conditions such as high temperature and wetness underground, the cables must be specially designed.

Although it is said that the cables should not be on the floor but should be placed on the wall, the size and weight of the cables careful installation It is necessary to provide. Details such as special machines and fine workmanship come into play.

There are risky work areas.

There are rarely safe areas for cable installation. Let’s say it is installed, as it is difficult to power these cables in case of any malfunction It may be necessary to wait for a long time. Considering that some metro lines operate almost continuously, the metro line will either be stopped to fix the malfunction, which means chaos or there will be no internet access for a long time.

There is no such thing as impossible. There are tunnels with internet access around the world.

Of course, it is not impossible to not have internet in metro tunnels. Although these procedures are quite expensive, there are countries that do this. For example in moscow Wi-Fi repeaters are located on trains, not tunnels. The signal comes through outside antennas.

In Turkey Metro Istanbul can be given as an example in this regard. It appears as one of the tunnels providing internet access.

Of course, it is possible to overcome this problem with technical and innovative solutions. By following the developments in this field in Turkey and around the world, experiencing a more comfortable and connected metro journey is no longer a distant prospect. not a dream.
