1) Distance from a cell
Each mobile phone communicates using radio waves that pass through the atmospheric space and become increasingly weaker.
This means that if your mobile phone is located very far from a cell, then the signal will be weak or even absent.
This situation is unlikely to occur in the city, but it is very frequent in the mountains or in uninhabited areas, where the cells are far from each other and can happen to be in an isolated area.
A mobile phone can theoretically reach a tower that is up to 70 kilometres away, even if because of the way mobile phones work, the actual limit is reduced to 30 kilometres, even in perfect conditions without obstacles and interference.
Basically, if you are distant from the cell, the only way to get your mobile phone to get a signal is to move towards it.
In the city, on the other hand, distance is a negligible factor, because the cells are so many and arranged in almost every corner of the street, so if the mobile phone doesn’t take well there is some other reason.
(2) Precautions and obstacles to signal (territory morphology)
Radio waves travel in a straight line from the cell phone to the cell tower, if there is any major impediment such as a hill or mountain range, radio waves will not be able to reach the tower.
For the same reason as before, in the city the presence of hills and unevenness of the ground should not give any problem.
The problem of obstacles in the city is represented by houses and palaces, since concrete, steel and most building materials are excellent at blocking cellular signals.
This is why in garages, cellars and basements there is often no mobile phone signal.
If it does not take home, your mobile phone should return online and find signal by going near a window or balcony.
3) Differences between operators
The cells in one area can serve a telephone operator instead of another, so it may be that in a given point take the Telecom instead of Wind or Vodafone instead of Tre.
It may therefore happen, always in more isolated areas, that only one operator is present, while the others do not have any signal due to the total absence of turrets.
We have already talked about this situation in the article on how to verify the mobile phone coverage in Italy of Telecom, Tre, Wind and Vodafone
Radio waves pass through the atmosphere and everything it is composed of, including rain, dust and ionized particles.
The signal can therefore be disturbed during a thunderstorm and will be stronger and more stable when the sky is clear, without rain and fog.
Even the cell towers, a bit like wifi routers, are designed to handle a number of contemporary connections.
While in richer or more populous areas, where there are many cells, this may not be a problem, different is the discourse in less populous rural areas.
The blockage of the cell is also the reason why in some tourist areas such as holiday villages at the seaside there may be problems with the cellular network, in particular for data connection to the internet (for example in Puglia this summer I found this problem).
In fact, it may be that the cells are few and not able to satisfy the seasonal users who come to populate a certain area only a few months of the year.
Other cases of clogging occur when, for example, you try to send New Year’s Day wishes at midnight or when you try to send an SMS or phone call or connect to the internet at the stadium or concert, where many people try to use your phone simultaneously.
6) Our speed of movement
It is normal if, travelling by car or train, the signal goes and comes.
Constant changes in position can have an effect on signal quality and the faster you go, the more unstable the cellular signal becomes.
7) Miscellaneous interferences.
Mobile phone radio waves can be disturbed if there are large, remotely controlled machines in the vicinity, such as cranes.
If the Crane’s large metal arm is moved to block electromagnetic waves, it can create a small shadow cone by attenuating nearby signals.
The radio frequencies of the Crane, which are very powerful, can then disturb the radio signals.
8) Problems of the phone to stabilize the connection to a cell.
Signal problems can also be caused by the phone itself, which instead of remaining connected to the nearest cell, takes the radio waves from a more distant cell, causing the reception notches to collapse suddenly.
In these cases, if you’re talking about Android smartphones, there are apps that can help you to optimize the reception of your mobile phone signal.
The cellular signal is a very complex thing to explain, especially if you start talking about radio frequencies that we deliberately ignored here.
There are many small factors that interfere with the cell phone signal and that can This is why one corner of your home might be a dead end point, but another one has a great signal.
Can you increase the reception of your mobile phone signal at home or in a specific environment?
If the signal is present, it is stable, but weak, then you can buy a cell phone repeater to increase reception.
